Tomato chlorosis virus p22 interacts with NbBAG5 to inhibit autophagy and regulate virus infection.

ABSTRACT: Tomato chlorosis virus (ToCV) is a member of the genus Crinivirus in the family Closteroviridae. It has a wide host range and wide distribution, causing serious harm to the vegetable industry. The autophagy pathway plays an important role in plant resistance to virus infection. Viruses and plant hosts coevolve in defence and antidefence processes around autophagy. In this study, the interaction between ToCV p22 and Nicotiana benthamiana B-cell lymphoma2-associated athanogenes5 Nicotiana benthamiana (NbBAG5) was examined. Through overexpression and down-regulation of NbBAG5, results showed that NbBAG5 could negatively regulate ToCV infection. NbBAG5 was found to be localized in mitochondria and can change the original localization of ToCV p22, which is colocalized in mitochondria. NbBAG5 in
