[Biolictic transformation of soybean by new selective marker gene resistant to dinitroanilines].

Biolistic transformation of soybean by construction carrying a mutant alpha-tubulin gene as selective marker gene conferring resistance to dinitroaniline herbicides, and by additional construction pAHTUBI carrying a full-length barley beta-tubulin gene for correct co-expression of exogeneous tubulin in cells of transgenic soybean lines has been realized. It was established that 10 microM trifluralin is the most optimal selective concentration to pick up transformed soybean lines. Transgenic nature of offained regenerants was confirmed by Southern blotting hybridization using specific probe to selective alpha-tubulin gene.
