Studies on transformation of indica rice with bt - toxin gene mediated by agrobacterium tumefaciens precultured immature embryo and callus derived from young panicle, immature embryo and mature embryo were used as acceptor for genetic transformation mediated by agrobacterium tumefaciens, the transformation rate of the above acceptor was investigated respectively. the results showed that immature embryo after precultured for 4 ~ 6d was the best. in respect to the concentration of agrobacterium tumefaciens when calli were cotransformated in medium yeb, to agrobacterium tumefaciens eha 105, od value of 0. 8 was the best

In this study, we constructed two plant expression vector with rip gene from barley and linked to two promoters which have high promoting efficiency in monocotyledonous plants, respectively, and then transferred to rice mediated by agrobacterium tumefaciens. the main factors of affecting transformation were investigated and established its regeneration and transformation systems. pcr analysis showed primarily that rip gene had already integrated into rice
