- 摘要:
- 以苜蓿品种“金皇后”为试材、以苜蓿子叶节为受体,通过农杆菌介导的转化方法,研究了抑菌浓度、子叶节生理期、侵染时间、共培养时间等因素对苜蓿子叶节遗传转化的影响,进而探索最佳转化条件,为建立高效的苜蓿子叶节遗传转化体系奠定基础。结果表明:用活化的OD600为0.6左右的农杆菌菌液进行浸染时,最佳受体材料为生长9日龄的子叶节,最佳浸染时间为20 min,共培养时间为3d,头孢霉素的抑菌浓度为500 mg/L。
- Abstract:
- Taking Medicago sativa ‘Jin Queen’ as material,taking cotyledonary nodes of alfalfa as transformation receptors,the effects of transformation of alfalfa cotyledonary node of factors,the cotyledon sections physiological period,infection time,the co-culture time on transformation frequency via Agrobacterium mediated transformation method were investigated.The object was to optimize transformation procedure,and lay a foundation for establishing the efficient alfalfa cotyledon node genetic transformation system.The results showed that infection with Agrobacterium (OD600=0.6),the optimal receptor material was 9-day-old cotyledon node,infection time 20 min,co-culture time 3d.The inhibitory concentration of cefotaxime was 500 mg/L.
