Abstract:

Apple stem pitting virus(ASPV)is a latent virus on apple and pear trees worldwide. Nicotiana occidentalis is an important herbaceous host plant for it. In this study,ASPV coat protein(CP)was used as bait to screen a cDNA library of N. occidentalis. Thirty proteins that interact with ASPV CP were obtained by yeast two-hybrid co-transformation and NCBI BLAST. This study could be useful for understanding the molecular mechanism of ASPV infection in N. occidentalis and the function of CP in the process of virus infection.

Key words: yeast two-hybrid, coat protein, apple stem pitting virus, protein interaction
