This paper is about flax (L. usitatissimum) genetic transformation by Agrobacterium tumefaciens mediated NP-1 gene. The transgenic plants express NP-1 gene steadily and be proved resistance to Fusarium Wilt.Research approach is to use 7309 variety as material, to base on tissue culture and Agrobacterium tumefaciens mediated, to build genetics transformation system, and we successfully gain transgenic ilax plants. We inoculate pathogen with flax plants through draw line and spray methods, to measure the abil...
