GbSOBIR1 confers Verticillium wilt resistance by phosphorylating the transcriptional factor GbbHLH171 in Gossypium barbadense.

ABSTRACT: Receptor-like kinases (RLKs) are important components of plant innate immunity. Although recent studies have revealed that the RLK suppressor of BIR1-1 (SOBIR1) can interact with multiple receptor-like proteins and is required for resistance against fungal pathogens, how the signal is transduced and triggers immune responses remains enigmatic. In this study, we identified a defence-related RLK from Gossypium barbadense (designated GbSOBIR1) and investigated its functional mechanism. Expression of the GbSOBIR1 gene is ubiquitous in cotton plants and is induced by Verticillium dahliae inoculation. Knock-down of GbSOBIR1 by virus-induced gene silencing resulted in attenuated resistance of cotton plants to V. dahliae, while heterologous overexpression of GbSOBIR1 in Arabidopsis improves resist
