摘要: 以郑58玉米自交系的种子作为试验材料,将玉米种子消毒,发芽后按长度分别将大、小2种玉米芽的生长点进行农杆菌转化,经过共培养后,通过对转化后的再发芽情况和转化芽的绿色荧光蛋白检测,分析玉米芽的大小对转化的影响。结果表明,玉米种子芽长度在0.3~0.5 cm时用于农杆菌转化,有利于农杆菌对玉米芽生长点的侵染转化和转化后芽的再生。

Abstract: The seeds of Zheng 58 maize inbred lines were used as experimental materials. After the corn seeds were sterilized and germinated, the growth points of big and small maize buds were transformed with Agrobacterium. After co-cultivation, the germination was carried out after transformation. By the situation and the results of green fluorescent protein detection of transformed buds, the effect of the size of maize buds on transformation was analyzed, and the size of maize buds suitable for Agrobacterium transformation was determined. The results showed that the maize seed buds were used for Agrobacterium transformation when they were 0.3~0.5 cm in length, which was beneficial to Agrobacterium tumefaciens infection and transformation of maize buds and post-transformation bud regeneration.

Key words: maize, bud length, Agrobacterium, transgenic
