Technique flow and Key Operation Points of Agrobacterium-mediated Genetic Transformation of Soybean Cotyledonary Node
摘要
Abstract
The low soybean genetic transformation frequency was one of the difficult problems that needed be resolved in soybean transgenie breeding. In this study, the soybean cotyledonary node was used as explants, and the technique flow and key operation points of Agrobacterium-mediated transformation method, including Agrobacterium preparation, explant and aseptic seedling preparation, infection and co-cultivation, adventitious bud induction, shoot elongation, regeneration of transgenie plantlets, plant habituation, obtaining of antibiotic resistant detection of transgenic plants, was systematically investigated.Therefore, a stable and efficient genetic transformation system using soybean cotyledonary nodes as explants was established.Using this transformation system, A1 gene isolated from Glycine soja was transformed into four soybean cultivars, including Suinong28, Hefeng55, Hefeng50 and Dongnong50. And several important factors affecting the transformation efficiency were also discussed in the explant.关键词
