摘要: 为了探究源于华山新麦草和簇毛麦的果聚糖合成酶基因6-SFT改良小麦(Triticum aestivum L.)抗非生物胁迫的可行性,以bar为筛选标记基因,通过基因枪介导法将Ph-6-SFTDv-6-SFT基因导入普通小麦(科农199)幼胚愈伤组织中,用除草剂草丁膦作为筛选剂筛选得到抗性植株,并对其进行PCR及GUS组织化学染色鉴定。结果显示,通过PPT筛选体系分别得到146株和187株抗性植株,其中PCR阳性植株分别为4株和6株,GUS组织化学染色阳性植株均为1株,转化率分别为0.24%和0.19%。结果表明,Ph-6-SFTDv-6-SFT基因已分别整合到小麦基因组中,获得了无抗生素标记基因的转基因小麦。

Abstract: To investigate the feasibility of fructan synthase gene 6-SFT derived from Psathyrostachys huashanica and Haynaldia villosa to improve the resistance of wheat (Triticum aestivum L.) to abiotic stress, the Ph-6-SFT or Dv-6-SFT gene was introduced into the young embryonic healing tissue of the common wheat family Kenong 199 by gene gun-mediated method using bar as a screening marker gene, and resistant plants were obtained by using the herbicide glufosinate as a screening agent and identified by PCR and GUS histochemical staining. The results showed that 146 and 187 resistant plants were obtained by the PPT screening system, of which 4 and 6 were PCR positive and 1 was GUS histochemically stained, respectively, and the transformation rates were 0.24% and 0.19%, respectively. The results showed that Ph-6-SFT and Dv-6-SFT genes had been integrated into the wheat genome, respectively, and transgenic wheat without antibiotic marker genes was obtained.

Key words: Triticum aestivum L., co-transformation, Ph-6-SFT gene, Dv-6-SFT gene, bar gene, expression cassettes
