Cysteine-rich receptor-like kinases (CRKs) are ubiquitous plant receptor-like kinases, which play a significant role in plant disease resistance. Gray mold is an economically important disease of grapes caused by Botrytis cinerea. However, CRK genes and their function in gray mold disease resistance in grapes have not been elucidated. This study aimed to identify and characterize CRKs in grapes and determine their role in gray mold resistance. Four CRKs were identified in Vitis amurensis and named VaCRK1–VaCRK4 according to their genomic distribution. The four VaCRKs were ectopically expressed in Arabidopsis thaliana to study their function in defense response against B. cinerea. Heterologous expression of VaCRK2 in A. thaliana conferred resistance to B. cinerea. VaCRK2 expression in gray mold-resistant grape cultivar increased significantly after B. cinerea inoculation and methyl jasmonate treatment. Furthermore, the expression of jasmonic acid (JA) signaling pathway-related genes in VaCRK2 overexpression lines of A. thaliana was significantly increased after B. cinerea inoculation, leading to the upregulation of pathogenesis-related (PR) genes and reactive oxygen species (ROS) accumulation. Overall, these results suggest that VaCRK2 confers resistance to B. cinerea by activating PR gene expression and oxidative burst through the JA signaling pathway.

Abstract Background The WRKYs are a major family of plant transcription factors that play roles in the responses to biotic and abiotic stresses; however, a comprehensive study of the WRKY family in roses (Rosa sp.) has not previously been performed. Results In the present study, we performed a genome-wide analysis of the WRKY genes in the rose (Rosa chinensis), including their phylogenetic relationships, gene structure, chromosomal locations, and collinearity. Using a phylogenetic analysis, we divided the 56 RcWRKY genes into three subgroups. The RcWRKYs were unevenly distributed across all seven rose chromosomes, and a study of their collinearity suggested that genome duplication may have played a major role in RcWRKY gene duplication. A Ka/Ks analysis indicated that they mainly underwent purifying selection. Botrytis cinerea infection induced the expression of 19 RcWRKYs, most of which had undergone gene duplication during evolution. These RcWRKYs may regulate rose resistance against B. cinerea. Based on our phylogenetic and expression analyses, RcWRKY41 was identified as a candidate regulatory gene in the response to B. cinerea infection, which was confirmed using virus-induced gene silencing. Conclusions This study provides useful information to facilitate the further study of the function of the rose WRKY gene family.
