Nicotianan benthamiana is a close relative of Nicotiana Tabacum. It’s widely used in studies of “Plant-Pathogen interactions”. Leaf-disk plant transformation method is widely used in plant molecular biology. In this research, we compared different parameters of different steps of Nicotiana benthamiana leaf-disk transformation procedure. We found co-cultivation at 18℃, balances the transformation frequency and late on selection better than the commonly used 25℃. Upon this pre-condition, we optimized parameters of the other steps of leaf-disk transformation of Nicotianan benthamiana. In the meanwhile, the research optimized the concentration of AgNO₃ and Phytagel of regeneration medium, in the context of bud’s induction. The research found that adding 4.3 mg/L AgNO₃and 8.8 g/L phytagel in the medium, gives the highest buds induction rate.
