Introduced infected by the turnip mosaic virus. there are many useful objective genes can be used in vegetable genetic transformation, but the research work of chinese cabbage genetic transformation is little. the reaserch on transforming chinese cabbage using agrobacterium - med ated method has n ' t been report at home and abroad. ln the test, tumv - cp gene was transferred into chinese cabbage ( brassica campestris l. ssp. pekinensis ) via agrobacterium - mediated method. a high effective regeneration and genetic transformatin system has been established, the detection by the method of molecular biology, has proved that the regenerative plants are transgenic plants and the target genes have been expressed transgenic plants partly. meanwhile transgenic progenies were traced and investigated so that heredity, stability and expression of target gene were researched. the virus resistant, stable plants were expected to obt ain so that theoretical base can be established for chinese cabbage breeding by gene engineering
利用農桿菌介導法轉化大白菜抗病基因的研究工作在國內外未見報道。本課試驗採用農桿菌介導法將tumv - cp基因導入大白菜中，建立了高效的大白菜離體再生、遺傳轉化體系，並對轉基因植株進行分子生物學檢測，證實得到的再生植株為轉基因植株，目的基因已在部分植株上表達。同時，對轉基因植株的後代進行檢測，分析該基因所控制性狀的遺傳穩定性以及基因表達情況，為大白菜基因工程抗病育種提供理論依據。
