Based on the panel data from 55 cities in the Yellow River Basin from 2012 to 2021, the coupling coordination degree model, exploratory spatio-temporal data analysis (ESTDA) method, and obstacle degree model were used to reveal the spatio-temporal evolution patterns of the coordinated development between new quality productivity and rural revitalization in the Yellow River Basin. The results showed that, ① in terms of timing changes, from 2012 to 2021, the average coupling coordination degree index between new quality productivity and rural revitalization in the study area ranged from 0.4 to 0.6, indicating a moderate coordination level, with a yearly increasing trend. In terms of spatial distribution, the coupling coordination level increased from the upstream to the midstream and downstream areas of the basin. Most cities showed a yearly increase in the coupling coordination level, but significant differences existed among cities. ②Spatio-temporal dynamic analysis indicated that the spatial pattern of the coupling coordination degree between new quality productivity and rural revitalization in the Yellow River Basin remained relatively stable during the study period. However, the integration of spatial pattern evolution was weak, and the synergistic development effect among regions was not obvious. The spatio-temporal transition matrix indicated that the spatio-temporal mobility probability of the coupling coordination degree was low during the study period, with inertia in the coordinated development levels, resulting in a relatively fixed local collaboration pattern among cities in the short term. ③Obstacle factor analysis revealed that during the study period, technological innovation capability, rural economic income, and rural greening issues gradually became factors restricting the development of the two subsystems of new quality productivity and rural revitalization in the Yellow River Basin. Therefore, measures needed to be taken to address regional development shortcomings to achieve coordinated and sustainable development of new quality productivity and rural revitalization in the Yellow River Basin.

Taking the new quality productivity and the development of agricultural and rural modernization as the research theme, the theoretical logic of the new quality productivity enabling agricultural and rural modernization development was expounded. Based on the relevant data of various provinces, the entropy method and the multivariate weighted comprehensive evaluation method were used to measure the national new quality productivity index and the national agricultural and rural modernization development index from 2010 to 2022, and then the internal influence mechanism and action mechanism of new quality productivity on the development of agricultural and rural modernization were empirically tested with the help of the threshold effect model. The results showed that new quality productivity could empower the endogenous driving force necessary for the development of agricultural and rural modernization. When the government management efficiency was taken as the threshold variable, there was a double threshold effect, but when the threshold was crossed, the promotion effect of the development of new quality productivity on the development of agricultural and rural modernization presented the basic characteristics of "diminishing marginal effect". When the level of marketization was taken as the threshold variable, there was a single threshold effect, and when it was in the low-intensity marketization, the new quality productivity inhibited the development of agricultural and rural modernization, but when the threshold was crossed, the promotion effect of the new quality productivity on the development of agricultural and rural modernization would show the basic characteristics of "increasing marginal effect", that was, with the improvement of the level of marketization, the positive effect of the new quality productivity would be enhanced.

Flavonoid 3′-hydroxylase (F3′H) is a key enzyme in the biosynthetic pathway of anthocyanins and proanthocyanidins in plant flavonoids, playing a crucial role in modifying flower and fruit colors, as well as enhancing stress resistance and pest resistance in plants. Barley （Hordeum vulgare L.） is rich in flavonoids and possesses health-promoting properties, and research on the F3′H gene in barley is significant for the development of medicinal and edible barley varieties rich in flavonoids. This review briefly introduced the discovery history of F3′H and its role in the biosynthetic pathway of anthocyanins and proanthocyanidins. At the genetic level, the F3′H gene had been cloned from various plants. Some studies have analyzed the formation and evolutionary history of this gene, while others have revealed the transcription factors associated with F3′H and its expression patterns in different tissues and under various environmental stress conditions. In some plants, the expression of the F3′H gene could enhance resistance of plants to stress and some pests and diseases. In barley, most of the structural genes involved in the flavonoid biosynthetic pathway have been cloned, with F3′H being one of the later genes to be cloned. Currently, multiple variants of this gene have been cloned and studied from several barley varieties, and these studies are of great significance for the future breeding of barley varieties rich in flavonoids.

To investigate the effects of river crab stocking density on soil and rice （Oryza sativa L.） growth in low-lying saline soil in Ningxia, the experiment was conducted with no crab stocking as the control, and low density (300 kg/hm²), medium density (450 kg/hm²) and high density (600 kg/hm²) crab treatments were set up to measure the relevant indexes of rice and rhizosphere soil at the tillering, spiking and milky maturity stages of the rice, so as to explore the growth status of rice under different crab stocking density in low-lying saline-alkaline land. The results showed that the low-density crabs stocking treatment could promote the increase of rice plant height and tiller number. From spiking to milky maturity stages of the rice, the medium-density crabs stocking treatment could reduce soil pH by 4.09%, which was significantly different from that of the low-density and high-density crabs stocking treatments (P<0.05), and it could reduce soil conductivity very significantly compared with that of the control group (P<0.01). The rice yield under the high density crabs stocking treatment increased by 14.60% and 5.69% compared with that under the low and medium density crabs stocking treatments, respectively, and the number of filled grains per panicle under this treatment was the highest, which was significantly different from that under the low and medium-density crabs stocking treatments (P<0.05). The rice yield and the number of filled grains per panicle were significantly positively correlated with the percentage of root activity in total absorption, respectively, and soil pH was significantly negatively correlated with soil ammonium nitrogen, available potassium and available phosphorus content（P<0.05 or P<0.01）. The study showed that the medium-density stocking of river crabs could reduce soil pH, and the high-density stocking of river crabs could increase the percentage of root activity in total absorption and filled grains per panicle rice, and promote the increase of yield.

To determine the control effect of bio-organic fertilizer added with biocontrol agent on soil-borne diseases of flue-cured tobacco, two treatments of commercial organic fertilizer (T1, CK) and bio-organic fertilizer (commercial organic fertilizer,Trichoderma harzianum agent and Bacillus amyloliquefaciens agent was mixed at a mass ratio of 6∶1∶1, T2) were set up. A field experiment was conducted to study the effects of organic fertilizer added with biocontrol agents on the incidence, disease index of bacterial wilt, black shank and root knot nematodiasis at 30,50 and 70 days after transplanting, as well as the yield and output value of flue-cured tobacco. The results showed that, after 30, 50 and 70 days of transplanting, compared with CK, the control effect of T2 on bacterial wilt was 47.0%,66.6% and 73.7%, the control effect on black shank was 38.8%,34.6% and 11.7%, and the control effects on root-knot nematodiasis were 60.0%,38.1% and 22.2%, respectively, indicating that the control effects of bio-organic fertilizer treatment on flue-cured tobacco bacterial wilt were stable and increased with the growth stage,while the control effects on black shank disease and root-knot nematodiasis were limited and the best effect was at the seedling stage. Compared with CK, the yield and output value of T2 increased by 10.6% and 10.2%, respectively, and the proportion of superior tobacco increased by 12 percentage points. The commercial organic fertilizer combined with Trichoderma harziensis and Bacillus amyloliquefaciens could significantly reduce the occurrence of tobacco bacterial wilt, have certain control effects on tobacco black shank disease and root knot nematodiasis, and improve the yield and output value of tobacco leaves after curing and the proportion of high-grade tobacco, which could be further promoted and applied in the tobacco-growing area of southwestern Guizhou Province.

In order to explore the adaptation mechanism of Haloxylon ammodendron seedling growth to the dynamic changes of ecological factors in its habitat, the relationship between growth indexes of Haloxylon ammodendron seedling and the soil moisture content and electrical conductivity in the root zone of Gurbantunggut Desert of Xinjiang was studied and analyzed. The results showed that the soil moisture content of seedlings root zone in the habitat area in late July was the lowest and the difference of soil moisture content in different habitat areas was also the smallest. The soil moisture content ranged from 0 to 3.75 %, and increased gradually with the increase of soil depth. The maximum soil electrical conductivity in habitat K (Karamay research area) and Q (Qitai County desert research area) appeared at 0~40 cm and 80~100 cm respectively, with values of 1 103.03 μS/cm and 244.23 μS/cm. The soil electrical conductivity in habitat area K was higher than that in habitat area Q. Among the growth indexes of Haloxylon ammodendron seedings, except for the ground diameter of seedlings, the plant height, crown width and shoot length were generally in the form of habitat area Q greater than habitat area K. Soil moisture content at seedling growth stage was positively correlated with plant height, crown area, tip length and ground diameter, and was significantly correlated with crown area(P<0.05). The correlation coefficients between soil moisture content and seedling crown area were 0.987 and 0.974 in habitat area K and habitat area Q, respectively. The correlation between soil electrical conductivity and seedling growth indexes was different in different habitat areas. The soil electrical conductivity of habitat area K and habitat area Q had the strongest correlation with seedling shoot length and crown area, and the correlation coefficients were 0.927 and 0.932, respectively (P<0.05). The soil moisture and electrical conductivity of root zone in habit area K and habit area Q were beneficial to the growth of Haloxylon ammodendron seedlings, but the soil in habit area Q was more suitable for the growth of Haloxylon ammodendron.

The temporal and spatial distribution characteristics of geological disasters in the middle and upper reaches of Hanjiang River Basin were studied, and the hidden trouble points of geological disasters, slope, elevation, precipitation and human activity indicators were selected to evaluate the susceptibility zoning. The results showed that the development type of geological disasters in the middle and upper reaches of Hanjiang River Basin was mainly landslide, accounting for 77.85%, and the development of land subsidence was the least, accounting for only 0.06%. From 2000 to 2021, the interannual changes of the total number of geological disasters and the number of various types of geological disasters were not large, and the overall trend was a fluctuating downward trend. The development of geological disasters in the middle and upper reaches of Hanjiang River Basin was mainly concentrated in the northern and southern mountains and river valleys in Shaanxi Province, and it was closely related to natural conditions such as the landform. The susceptibility of geological disasters was divided into four levels. The non-susceptible zone accounted for the largest proportion of the total area at 42.36%, followed by the low-susceptibility zone at 25.64%, the moderate-susceptibility zone at 25.08%, and the high-susceptibility zone at 6.92%. In general, the probability of geological disasters in the middle and upper reaches of Hanjiang River basin was low.

Based on the land use data of Taiyuan City, Shanxi Province from 2000 to 2020, the Fragstats software was used to calculate the landscape pattern index and analyze the change of landscape pattern. The “pressure-state-response” (PSR) model and entropy weight method were used to evaluate the ecosystem health status of Taiyuan City. The results showed that cultivated land, grassland and forest land were the dominant landscape types in Taiyuan City, and their areas accounted for a large proportion. The construction land area expanded year by year, and the increase was large. The area of water and other land types was small, and the connectivity was poor. The overall landscape showed a trend of homogeneity and diversification, and the fragmentation of the landscape was deepened. The overall ecosystem health of Taiyuan City showed the distribution pattern of good in the north and south region, and bad in the central region. The comprehensive index of ecosystem health in Taiyuan City showed a downward trend from 2000 to 2015, and reached the lowest value in 2015. The comprehensive index of ecosystem health increased from 2015 to 2020. The indicators of urbanization, population density and human disturbance were significantly correlated with ecosystem health in Taiyuan City（P<0.01）.

The field experiments were conducted by using 6 pairs of rapeseed combinations with resistance and corresponding non-resistant isogenic lines to investigate the differences in disease resistance, agronomic traits and yield when resistance loci CRa/CRb and PbBa8.1 were introgressed into different varieties (materials). The results showed that the incidence rate of all non-disease resistant materials in 6 pairs of rapeseed combinations was more than 97.8%, and the disease index was over 95.6. The incidence and disease index of the materials introgressed with the CRa/CRb resistance locus were higher, the incidence was 96.7%, 86.0% and 82.2%, respectively, and the disease index was 85.9, 67.7 and 36.0, respectively, but both were lower than those of the corresponding non-resistant isogenic materials; the materials introgressed with the PbBa8.1 resistance locus exhibited better resistance to clubroot, the incidence was 10.6%, 1.8% and 5.8%, respectively, and the disease index was 8.0, 1.5 and 4.7, respectively. The agronomic traits of rapeseed introgressed with the CRa/CRb resistance locus, such as plant height, effective branch location, effective number of pods per plant and number of kernels per pod, were lower than those of rapeseed introgressed with the PbBa8.1 resistance locus, which ultimately affected the yield.

In order to improve the utilization efficiency of tobacco(Nicotiana tobacum L.) waste, the control effects of two kinds of tobacco waste and quicklime with different compounding ratios on Pomacea canaliculata were studied. Tobacco leaf and peduncle were used alone and mixed with quicklime in different proportions (mass ratios of 4∶1, 2∶1, 1∶1, 1∶2, 1∶4, total mass concentration of 0.2 g/L), to explore their effects on survival, behavior, feeding and growth of Pomacea canaliculata. The results showed that the combination of tobacco waste and quicklime had strong toxic effects on Pomacea canaliculata and constrained the feeding and growth of surviving individuals, and the overall trend was that the higher the percentage of quicklime content, the more obvious the inhibition effect on Pomacea canaliculata. In terms of the survival, behavior, feeding and growth of Pomacea canaliculata, the control effects of tobacco leaf on the snails were stronger than that of tobacco peduncle whether used alone or in combination with quicklime, that and more than 95% of the snails died within 14 d. The composite treatment of tobacco leaves and quicklime made it difficult for the snails to eat, and the snails avoided the damage of the two by closing the operculum. Moreover, with the increase of quicklime content and treatment time, the proportion of the snails with closed operculum was growing, even up to 100%. The food intake of Pomacea canaliculata decreased significantly under the single use of tobacco and quicklime and their mixture, meanwhile, the weight growth rate, feeding rate and specific growth rate were significantly inhibited except under the single use of tobacco peduncle. The combination of tobacco waste and quicklime showed controlling effects on Pomacea canaliculata, and the addition of quicklime could improve the utilization efficiency of tobacco waste.

To investigate the impact of exogenous betaine on the physiological characteristics of Bougainvillea spectabilis under NaCl stress and to determine its optimal alleviating concentration, two-year-old potted Bougainvillea spectabilis ‘Crimsonlake’ were used as experimental materials, after simulating salt stress with a 200 mmol/L NaCl solution, exogenous glycine betaine was applied at concentrations of 50, 100, and 150 mmol/L(T1, T2, T3), with water maintenance after NaCl stress (CK) serving as the control group. The effects of different treatments on leaf relative conductivity, malondialdehyde (MDA), proline, and the activities of superoxide dismutase (SOD), peroxidase (POD), and catalase (CAT) were determined, and the alleviating capacity of betaine at different concentrations against NaCl stress was comprehensively evaluated. The results showed that the application of exogenous glycine betaine after NaCl stress significantly reduced leaf relative conductivity and MDA content, while obviously increasing proline and the activities of POD, SOD, and CAT, indicating that exogenous glycine betaine could effectively alleviate the damage of NaCl stress to Bougainvillea spectabilis ‘Crimsonlake’. Principal component analysis and fuzzy function analysis revealed that the application of 100 mmol/L exogenous glycine betaine was the most effective in alleviating the stress of NaCl on Bougainvillea spectabilis ‘Crimsonlake’.

To explore the leaf functional traits and environmental adaptability of garden greening trees in Xiamen City, 10 kinds of garden trees were selected for study, and their leaf functional traits, ecological stoichiometric characteristics and physiological indicators were determined respectively. The results showed that there were significant differences in leaf shape index (LI), specific leaf area (SLA), leaf dry matter content (LDMC) and leaf water content (LWC), malondialdehyde (MDA) content, free proline (Pro) content, catalase (CAT) activity, leaf carbon content per unit mass(LCC), leaf nitrogen content per unit mass(LNC), carbon to nitrogen ratio (C∶N) among 10 species of garden trees. Correlation analysis showed that LI was extremely significantly positively correlated with LWC, extremely significantly negatively correlated with LDMC, and negatively significantly correlated with LNC; SLA was extremely significantly positively correlated with LWC, LNC and C∶N; MDA was extremely significantly negatively correlated with LWC and C∶N; LCC was extremely significantly positively correlated with C∶N and extremely significantly negatively correlated with LNC; CAT was negatively significantly correlated with Pro. Principal component analysis and membership function analysis showed that Delonix regia, Alstonia scholaris and Ficus microcarpa among 10 common garden trees showed better adaptability to Xiamen City under the same environment. Leaf strategy analysis showed that Delonix regia, Alstonia scholaris and Ficus microcarpa belonged to the “slow investment-return” growth strategy (i.e. higher SLA and LDMC and lower LNC), which were more suitable for using as the main tree species in urban landscape planning of Xiamen City.

The purpose of the study is to explore the impact of crop tree release on the spatial structure of Pinus massoniana and broadleaf forests after the removal of pine wilt disease-infected trees, with the objective of optimizing forest structure, promoting forest growth, and enhancing broadleaf transformation to improve ecological functions. Eight 20 m × 20 m standard plots were set up, four-neighbor tree spatial structure units were used to calculate the uniform angle index, the mingling degree, layering index, openness, and Hegyi competition index, and the spatial structure before and after simulating crop tree release was compared. The results showed that after crop tree release, the average mingling degree of the eight plots increased from 0.604 to 0.668; changes in the uniform angle index of most plots indicated that tree distribution tended to be random; the average openness increased from 0.299 to 0.361, improving light conditions and growth space; the average layering index increased from 0.576 to 0.608, and the complexity of the vertical structure of trees in six plots increased; the average Hegyi competition index decreased from 0.875 to 0.751, relieving competition pressure among trees. Crop tree release strategies could significantly optimize the spatial structure of P. massoniana and broadleaf trees mixed forests, reduce competition pressure among trees, promote mingling degree and structural complexity, enhance species diversity, productivity, and stability of forests, and facilitate broadleaf transformation, thereby improving ecological functions.

The purpose of this study was to explore the potential constituents responsible for α-glucosidase inhibitory activity of medicine food homologous herbs Eugenia caryophyllata and Cinnamomum cassia. The α-glucosidase inhibitory effect of crude extracts from Eugenia caryophyllata and Cinnamomum cassia were preliminary determined by in vitro enzyme activity experiment. The corresponding bioactive constituents were determined by the combined use of high-resolution inhibition profiling and ultra-high performance liquid chromatography-quadrupole time-of-flight mass spectrometry (UPLC-QTOF-MS/MS). The results showed that, crude methanol extracts of Eugenia caryophyllata and Cinnamomum cassia displayed considerable inhibition towards α-glucosidase with IC₅₀values of (50.0±0.08) μg/mL and (2.19±0.17) μg/mL, respectively, more active than the positive control acarbose [IC₅₀=(264.37±2.73) μg/mL]. The high-resolution inhibition profiles pointed out that polyphenols were correlated with α-glucosidase inhibitory activity. In addition, flavonoids from Eugenia caryophyllata, cinnamic acid and 2′-methoxy cinnamaldehyde from Cinnamomum cassia were considered as the possible inhibitors by the careful analysis of UPLC-QTOF-MS/MS data. The results supported further research with the aim of developing Eugenia caryophyllata and Cinnamomum cassia into functional food for prevention and management of T2D and T2D-related complications.

In order to understand the genetic evolution direction and pathogenicity of Avian leukosis virus (ALV) isolated from Jianghan chickens, pathological dissection, virus isolation and identification on Jianghan chicken suspected of ALV infection in Wuhan, Hubei were conducted. The isolated viral strains underwent genetic evolution analysis of the env gene and pathogenicity evaluation. The post-mortem results revealed splenomegaly in diseased chickens, with visible tumors on the liver surface. Following inoculation of homogeneous tissue onto DF-1 cells, ELISA and IFA assays showed positive P27 antigen findings. Subsequent PCR subtype identification only amplified specific bands for the J subgroup, indicating the successful isolation of an ALV-J strain named HB18449. Genetic evolution analysis of the isolated strain’s env gene demonstrated the closest genetic relationship to the Shandong commercial egg chicken strain SD13QJ03 and clustered with most local chicken isolates in the same major branch as the UK prototype strain HPRS103. Furthermore, pathogenicity experiments revealed that infection with HB18449 inhibited chick growth, impaired immune organ development, induced viremia, decreased the CD4⁺/CD8⁺ T lymphocyte ratio in blood, and reduced humoral immune response levels.

To improve the utilization rate of theaflavins, the reverse-solvent method was used to prepare whey protein-theaflavins(WP/TF) nanoparticles. The embedding rate and stability constant were used as indexes. The optimal preparation process was determined by single factor and orthogonal tests, and the performance of particle size, Zeta potential, gastrointestinal simulated digestion and storage stability were studied. The results showed that the optimum preparation process for whey protein-theaflavins nanoparticles was the WP/TF mass ratio of 10∶1, hydration temperature of 55 ℃, and hydration time of 1.5 h. The resulting nanoembedding rate was 85.89%, particle size was (557.05±32.55) nm, Zeta potential was (-58.83±3.05) mV, and the resolubility and water solubility were good. Under simulated gastrointestinal digestion, the TF release rate of nanoparticles was significantly reduced, and it had a good slow release effect. After 30 days of storage at 4 ℃ and 25 ℃, the inclusion rate decreased, but the inclusion rate remained above 70% at 4 ℃. Therefore, whey protein-theaflavins nanoparticles exhibited good stability and slow release performance and could improve the utilization rate of theaflavins, which was highly important for the development and utilization of theaflavins.

：The effects of different indoor starvation and purification times (0, 1, 2, 3, 4, 5 d) on the quality parameters such as basic nutritional composition, water holding capacity, texture, and histological characteristics of Siniperca chuatsi were studied. The results showed that with the increase of starvation time, the fat content began to decrease significantly from the second day, significantly lower than the control group before starvation. The protein content of the muscles of Siniperca chuatsi on the second day of starvation was significantly higher than that before starvation. The muscle pH of Siniperca chuatsi first significantly increased and then began to decrease, reaching its highest value on the second day of temporary starvation. Short-term temporary starvation had an impact on the water holding capacity of fish meat, the storage loss rate was the lowest on the second day of temporary starvation, and it started to recover from the third day. The storage loss rate of Siniperca chuatsi meat in 24 h and 72 h on the fourth and fifth days was higher than that before starvation. After temporary starvation, the muscle hardness and chewiness of Siniperca chuatsi first increased, and decreased significantly on the fourth and fifth days. The recovery of Siniperca chuatsi muscle showed little variation in the first three days, and the recovery of fish meat increased on the fourth and fifth days. Compared with before temporary starvation, the muscle fiber diameter of Siniperca chuatsi decreased first and then increased after temporary starvation. On the second day of temporary starvation, the muscle fiber diameter was the smallest and the muscle fiber density was the highest, significantly higher than that before temporary starvation. Temporary starvation could improve the microstructure, meat quality, and the body color of Siniperca chuatsi, and increase its brightness and whiteness. The experimental results indicated that short-term temporary starvation could improve the muscle quality of Siniperca chuatsi to a certain extent. Considering the comprehensive quality effect and production economic benefits, the suitable indoor temporary starvation purification treatment time for Siniperca chuatsi under the experimental conditions was 2 days.

To investigate the thermal stability of cinnamon volatile oil, the oil was extracted using steam distillation. The chemical composition of the oil before and after heating was analyzed by gas chromatography-mass spectrometry (GC-MS), and the optimal heating temperature and duration were screened. Five antioxidants,namely carvacrol, butylated hydroxytoluene (BHT), propyl gallate (PG), octyl gallate, and thymol,were selected to evaluate their effects on maintaining the thermal stability of the oil. The results showed that 64 components of cinnamon volatile oil were identified by referencing the Mainlib standard mass spectrometry database combined with manual interpretation. The optimal heating conditions were determined as 100 ℃ for 8 h. Significant differences were observed between the heated cinnamon volatile oil without antioxidant intervention (experimental control) and that treated with antioxidants, indicating that antioxidants could maintain the thermal stability of the oil to varying degrees. Thymol exhibited the strongest inhibitory effect on the thermal decomposition of trans-cinnamaldehyde, followed by PG.

In response to the common problems of high breakage rate and flattened appearance in the mechanized shaping of Enshi Yulu tea, this study focused on the commonly used shaping equipment 60K-S fine rolling machine for Enshi Yulu tea mechanized production. Three different types of washboards were designed, optimized, and tested in production. The results showed that the third washboard had the best shaping effect, with a tooth height of 7 mm, a rounded tooth corner of 2.0 mm, and a rounded tooth groove corner of 3 mm. The triangular teeth in the middle of the washboard were changed to round straight strips.The changes in the structure of the washboard had a significant impact on shape and fragmentation, but had a relatively small impact on clarity and color. Reducing the height of the washboard teeth, increasing the rounded corners of the rubbing teeth, and adding rounded tooth grooves had a significant impact on the crushing of tea leaves, resulting in more uniform tea leaves and less breakage.

The potato (Solanum tuberosum) was used as the research object. The cDNA sequence of the Rieske FeS gene of the potato was cloned by RT-PCR technology, and bioinformatics analysis was performed on the gene. The expression of the Rieske FeS gene under simulated drought stress (0, 12, 24 h) was detected by fluorescence quantitative PCR. The results showed that the full-length cDNA sequence of the potato Rieske FeS gene was 693 bp, containing one open reading frame and encoding 230 amino acids. The molecular weight of the potato Rieske FeS protein was 24.27 ku, with a theoretical isoelectric point of 8.20;the Rieske FeS protein contained the CytB6-F_Fe-S domain (59~97 aa), transmembrane region (72~94 aa), and Rieske domain (113~203 aa);the secondary structure of potato Rieske FeS protein had the highest proportion of irregular curls, followed by β-sheets, and the lowest proportion was α - helices. The phylogenetic tree analysis showed that the potato Rieske FeS protein was most closely related to the tobacco Rieske FeS protein. The qPCR results showed that the Rieske FeS gene of the potato was expressed in all tested tissues, with the highest relative expression level of Rieske FeS gene in leaves, followed by stems and roots, and the lowest relative expression level in tubers. After PEG drought stress, the relative expression level of Rieske FeS gene in leaves showed a decreasing trend followed by an increasing trend, and the relative expression level at 12 hours was significantly lower than that at 0 hours (control group). The relative expression level of Rieske FeS gene in stem segments was significantly upregulated after 12 hours of simulated drought treatment; the relative expression level of Rieske FeS gene was significantly upregulated in tubers under simulated drought stress for 24 hours; there was no significant difference in the relative expression levels of Rieske FeS gene among the drought treatments in the roots. The potato Rieske FeS gene was closely related to drought stress.

Using provincial panel data from 2009 to 2023 as a sample, the heterogeneity of the impact of financial subsidies and farmers’ income on agricultural insurance across different regions was studied based on the characteristics of agricultural production. A "horizontal + vertical" reverse approach was employed to analyze the impact of farmers’ income on agricultural insurance. The study found that, on a national level, financial subsidies and farmers’ income had a significant positive impact on agricultural insurance, with the influence of financial subsidies being greater than that of farmers’ income. Regionally, farmers’ income had a significant positive impact on agricultural insurance density across all regions, while financial subsidies generally had a positive impact, except in the western region where it was negative. The coefficient of per capita agricultural insurance payment, per capita agricultural output value and rural compulsory education proportion had all been positive, but the influence intensity had varied with different regions. The per capita agricultural loan and the degree of disaster had different impacts on agricultural insurance density in different regions. The coefficient of per capita agricultural loan in Northeast China had been positive, while that in other regions had been negative. The degree of disaster had been positive except for the central region, where the coefficient had been negative. Based on these findings, the study suggested implementing differentiated financial subsidies, optimizing the insurance environment, expanding the coverage of agricultural insurance to safeguard farmers’ income, and increasing farmers’ education and training to improve their overall quality.

Based on panel data from 30 provinces(municipalities and autonomous regions) in China from 2010 to 2019, the mediation effect model was used to empirically analyze the impact of digital economy on carbon emissions. The results showed that there was a significant negative correlation between the development of digital economy and carbon emission intensity. The digital economy could reduce carbon emission intensity through rationalization of industrial structure. The impact of the digital economy on carbon emission intensity was more significant in the eastern region and coastal areas, and the inhibitory effect on regions with higher carbon emission intensity was more obvious. It was proposed that the government and relevant departments should accelerate the construction of the digital economy, promote the equalization of the industrial structure, implement heterogeneity strategies, coordinate regional development, and promote synergy between economic development and environmental governance.

Taking Licheng County, Changzhi City, Shanxi Province as an example, this study proposed influencing factors of cultivated land abandonment from four aspects: natural conditions, economy, population, and production, based on literature review, field surveys, and expert interviews. The DEMATEL-MICMAC-ISM model was employed to analyze the correlations, importance, hierarchical structure, and driving force-dependency relationships of these factors. The results showed that the 15 influencing factors of cultivated land abandonment were divided into 3 clusters across 6 levels: Direct factors (L1), intermediate factors (L2, L3, L4, L5), and deep factors (L6). Using the MICMAC model, the dependency and driving force values of each factor were calculated, and the driving factors were categorized into four types: linked factors, independent factors, autonomous factors, and dependent factors. Key factors influencing cultivated land abandonment included terrain slope, elevation, background value, expenditure on agriculture, forestry, and water affairs, total agricultural machinery power, location conditions, tillage convenience, and distance to water sources.

The relationship between Shandong Province and RCEP agricultural products export trade from 2007 to 2021 was analyzed by selecting the data of Shandong Province and RCEP agricultural products export trade, and the empirical analysis was carried out by using the expansion trade gravity model. The results showed that the economic size (GDP), population size and opening-up level of RCEP member countries promoted the export of agricultural products in Shandong Province, while the relative distance between RCEP member countries and Shandong Province, the proportion of agricultural employment, whether they were developed economies and whether there were common economic and trade organizations had inhibitory effects on the export of agricultural products in Shandong Province; the average trade potential of Shandong Province’s agricultural products to RCEP countries showed pioneering trade, while the trade potential coefficient of Cambodia, Laos, Thailand and Vietnam had decreased significantly, and had been transformed from potential re-shaping to great potential. Japan, South Korea, Australia, Brunei, Malaysia, the Philippines, Singapore and other countries showed pioneering potential. Myanmar showed potential for re-shaping. Based on this, the following suggestions were put forward: Pay full attention to the signing of the RCEP agreement and stabilize the export growth rate; focus on optimizing the export structure of agricultural products, and strengthen the characteristic and advantageous industries; fully tap the potential of export trade and open up export market space; do a good job in connecting and providing services to RCEP.
