The sucrose nonfermenting 1-related protein kinase (SnRK) plays an important role in responding to abiotic stresses by phosphorylating the target protein to regulate various signaling pathways. However, little is known about the characteristics, evolutionary history, and expression patterns of theSnRKfamily in black raspberry (Rubus occidentalisL.) or other Rosaceae family species. In this study, a total of 209SnRKgenes were identified in 7 Rosaceae species and divided into 3 subfamilies (SnRK1,SnRK2,andSnRK3) based on phylogenetic analysis and specific motifs. Whole-genome duplication (WGD) and dispersed duplication (DSD) were considered to be major contributions to theSnRKfamily expansion. Purifying selection was the primary driving force in theSnRKfamily evolution. The spatial expression indicated that theRoSnRKgenes may play important roles in different tissues. In addition, the expression models of 5RoSnRK2genes in response to abiotic stresses were detected by qRT-PCR. The proteins encoded byRoSnRK2genes localize to the cytoplasm and nucleus in order to perform their respective functions. Taken together, this study provided an analysis of theSnRKgene family expansion and evolution, and contributed to the current knowledge of the function of 5RoSnRK2genes, which in turn expanded understanding of the molecular mechanisms of black raspberry responses to abiotic stress.
