摘要
Dear Editor,A variant with single substitution in the LRR-only protein CsLRR1,which regulates cucumber resistance to powdery mildew through a salicylic-acid-mediated pathway,provides a major source of resistance for cucumber breeding.Cucumber powdery mildew(PM),mainly caused by the biotrophic pathogen Podosphaera xanthii(synonym Podosphaera fusca),poses a serious threat to cucumber crops globally,leading to substantial reductions in fruit yield and quality(Martinez-Cruz et al.,2017).
