摘要：The pH7GWIWG2 (II) expression vectors of capsid protein gene sequences constructed in our lab contain Lily symptomless virus (LSV) and Lily mottle virus (LMoV). Lilium orientalus 'Sorbonne' and Lilium longiflorum,'White Heavenan' are the receptor, using Agrobacterium-mediated transformation to lily. The results show that: 'Sorbonne' and 'White Heaven' were infected with Agrobacterium bacteria (OD600 = 0.8) 15 min, fostered dark for 4 d, respectively adapter red off bacteria with cefotaxime (300 mg/L) train the filter to the selection medium containing 23.0 mg/L and 25.0 mg/L hygromycin to obtain transgenic lily. RT-PCR assay prove that the two encoding viral capsid protein gene have expressed in the lily genome, ELISA and Western blot show that the transformation of lily significantly enhance the resistance to LSV and LMoV.
