After having established genetic transformation system with tomato cotyledons as explant and determined the transformable of preculture time,incubation time and co-culture time,we set up the system of high frequency transformation of tomato cotyledons.Then hBMP-3m gene was transferred into tomato via Agrobacterium-mQdiated transformation,and the resistant plants to Hyg were obtained.
