A transgenic wheat with a stilbene synthase gene resistant to powdery mildew obtained by biolistic method

Stilbene, a kind of phytoalexin, plays an important role in resistance to f ungal and bacterial infection in plants. It strongly inhibits the growth of fungi and sprout of spore. Stilbene synthase gene (Vst1) obtained from gra pevine has been transferred into common spring wheat Jinghong 5 by using th e biolistic transformation method. Five transgenic plants (T-0) were obtain ed from the bombarded 2014 immature embryos. One immune plantlet and 3 plan tlets with mid-resistance to powdery mildew were identified from the transg enic plants of T-3 generation which came from 2 T-0 transgenic plants.
