植物正链RNA病毒外壳蛋白的非结构功能研究进展

uring the infection of plant viruses, their coat proteins (CPs) mainly package viral genomic RNAs and protect them away from degradation. In addition, amounting experimental evidences demonstrate that CPs also serve as multifunctional proteins involved in most stages of the viral infection cycles through specific interactions with viral and/or host factors. This review focuses on the non-structural functions of the CPs in the viral transmission, replication, translation, interaction with host factors, etc. In addition, the CPs' functions are regulated by post-translational modifications, such as phosphorylation and ubiquitination, which also affects viral infection cycles. In the end, the research perspectives and potential applications about CPs' non-structural functions are discussed.
