Genome-Wide Identification and Expression Analysis of SNARE Genes in

SNAREs (soluble -ethylmaleimide-sensitive factor attachment protein receptors) are central components that drive membrane fusion events during exocytosis and endocytosis and play important roles in different biological processes of plants. In this study, we identified 237 genes encoding SNARE family proteins in in silico at the whole-genome level. Phylogenetic analysis showed that BnaSNAREs could be classified into five groups (Q (a-, b-, c-, bc-) and R) like other plant SNAREs and clustered into twenty-five subclades. The gene structure and protein domain of each subclade were found to be highly conserved. In many subclades, are significantly expanded compared with the orthologous genes in . genes are expressed differentially in the leaves and roots of . RNA-seq data and RT-qPCR proved that some of the are involved in the plant response to infection as well as treatments with toxin oxalic acid (OA) (a virulence factor often secreted by ) or abscisic acid (ABA), methyl jasmonate (MeJA), and salicylic acid (SA), which individually promote resistance to . Moreover, the interacted proteins of BnaSNAREs contain some defense response-related proteins, which increases the evidence that BnaSNAREs are involved in plant immunity. We also found the co-expression of BnaSYP121/2s, BnaSNAPs, and BnaVAMP722/3s in due to infection as well as the probable interaction among them.
