GATA8-Mediated Antiviral Defence Is Countered by Tomato Chlorosis Virus-Encoded Pathogenicity Protein p27.

ABSTRACT: Tomato chlorosis virus (ToCV), a phloem-restricted RNA virus within the genus Crinivirus of the family Closteroviridae, exhibits a broad host range and severely impacts the yield and quality of multiple crops. Viral infection directly alters endogenous phytohormone levels, which are intricately associated with viral mobility, replication, symptom development and defence mechanisms. Previous studies have demonstrated that GATA transcription factors regulate several hormone signalling pathways in plants. In this study, we explored the interaction between ToCV p27 and SlGATA8/NbGATA11. Results indicated that ToCV p27 interacts with an 18-amino-acid at the C-terminus of SlGATA8 and NbGATA11 proteins. Silencing and overexpressing of SlGATA8 revealed its positive role in regulating tomato defenc
