Abstract: The recombinant plasmid vector p139035S-KGF1 was constructed and transfected into safflower by Agrobacterium tumefaciens transfection. The period of infection to rooting was 14 weeks, and transformation efficiency was about 0.1%. Adventitious shoots were generated after cotyledons were cultured in selecting media containing hygromycin for 4–5 weeks. Rooted safflower was obtained in 4–8 weeks. KGF-1 was transformed into safflower chromosomes and expressed successfully, as determined by PCR, Southern blot, RT-PCR and Western blot analysis, which established the basis for the production of KGF-1.
