摘要: Soybean mosaic virus (SMV), a member of the Potyvirus genus, is one of the most prevalent and devastating viral pathogens in soybean-growing regions worldwide. It is generally accepted that symptom development of a viral plant disease results from molecular interactions between the virus and its host plant. P3 protein is the most variable polyprotein in potyviruses, which potentially plays an important role in the process of the evolution of virus type specialization. However, P3 not only plays a major role in virus replication and movement, but it is also responsible for symptom development in SMV-infected plants. This study provides evidence that actin-depolymerizing factor 2 (designated as ADF2) of soybean interacts with SMV P3 via a two-hybrid yeast system by screening a soybean cDNA library. Bimolecular fluorescence complementation assay further confirmed the interaction, which occurred in both the cytomembrane and cytoskeleton of Nicotiana benthamiana cells. The results support the hypothesis that SMV P3 might have a role in virus movement within cells.
