The Transcription Factor OsWRKY30 Regulates Rice Resistance to Southern Rice Black Streaked Dwarf Virus Disease.

ABSTRACT: WRKY transcription factors are important plant regulators that participate in diverse biotic and abiotic stress responses. However, their roles in resistance to Southern rice black-streaked dwarf virus (SRBSDV) remain unknown. Previous work demonstrated that the histone deacetylase gene OsHDA706 (LOC_Os06g37420) enhances SRBSDV resistance by promoting jasmonic acid (JA) biosynthesis. In this study, we first confirmed that the rice line GR216 exhibits strong resistance to SRBSDV through artificial inoculation. Knockout of OsHDA706 in GR216 led to typical SRBSDV symptoms, including dwarfing, dark-green wrinkled leaves, and inverted fibrous roots, confirming its role in antiviral defense. Using the RiceTFtarget database and yeast one-hybrid experiments, we identified OsWRKY30 (LOC_Os08g38990)
