High Temperature Promoted the Accumulation of Citrus Yellow Mosaic Virus in Citrus sinensis via Weakening the Immune Function of the CsWRKY76-CsPR4A Modules.

ABSTRACT: Rising global temperatures exacerbate the severity of crop diseases, threatening global agricultural production. Citrus yellow mosaic virus (CYMV) is one of the pathogens that seriously threaten citrus production, the world's largest fruit industry. However, the molecular mechanisms underlying CYMV-citrus interactions at high temperatures remain poorly understood. Over a 1-year observation period, this study found elevated temperatures increased CYMV accumulation in Madam Vinous sweet orange. Controlled experiments comparing 25°C and 37°C conditions further validated this phenomenon, with significantly higher viral titres observed under high-temperature treatments (37°C). Subsequent transcriptomic analysis revealed that the transcription factor CsWRKY76 and the pathogenesis-related gene Cs
