Abstract: In this study,the MYB transcription factor GmPHR1 was transformed into three soybean genotypes?by Agrobacterium-mediated different explants. The results showed that the shoot tip transformation system was with?the highest shoot induction,shoot regeneration,transformation ratios and little genotype dependence. But it was the?least sensitive to antibiotics,so there were some escapes in this system. The transformation system with embryonic tip?was higher in shoot induction,shoot regeneration and transformation ratios. In addition,it was more sensitive than?others to antibiotics,so embryonic tip transformation was a more ideal soybean genetic transformation system. The?cotyledonary node transformation and the hypocotyl transformation systems were lower in shoot induction,shoot regeneration and transformation ratios and significant differences among genotypes existed. By using the above transformation systems T1transgenic lines of the three soybeans were obtained.

Key words: Soybean, Agrobacterium-mediated transformation, Explant types, Transgene
