| Abstract: | The research on the genetic stability of transgenic plants is necessary,which is important for further use the transgenic plants.The transgenic chi+rip fungal-resistant soybean(G0431,G0433) and their successive generations T2,T3 and T4 were studied in present paper.The two anti-fungal genes were stably co-intergrated in genome and transmitted over successive generations monitored by PCR,Southern Blot analysis and Real-Time PCR.The results of Real-time RT-PCR,Western Blot and the resistance to P.megasperma identified that no significant difference in the progenies of transformed plants till T4,indicating the resistance to P.megasperma was stably inherited over successive generations.The transgenic chi+rip fungal-resistant soybean would be valuable to develop new transgenic soybean varieties with high efficiency against fungal. |
