Contribution of a WRKY Transcription Factor, ShWRKY81, to Powdery Mildew Resistance in Wild Tomato.

ABSTRACT: Tomato powdery mildew, caused by Oidium neolycopersici, is a destructive fungal disease that damages almost all of the aerial parts of tomato, causing devastating losses in tomato production worldwide. WRKY transcription factors are key regulators of plant immunity, but the roles of ShWRKYs in wild tomato Solanum habrochaites LA1777 against O. neolycopersici still remain to be uncovered. Here, we show that ShWRKY81 is an important WRKY transcription factor from wild tomato Solanum habrochaites LA1777, contributing to plant resistance against O. neolycopersici. ShWRKY81 was isolated and identified to positively modulate tomato resistance against On-Lz. The transient overexpression of the ShWRKY81-GFP (green fluorescent protein)
