The GRAS protein family encodes a family of plant-specific transcription factors that have diverse and significant functions in regulating plant development and anthocyanin biosynthesis. Our study represents the comprehensive identification and comparison of GRAS protein family genes in the Rosaceae. Here, 535  GRAS  genes were screened from eight Rosaceae species. Phylogenetic analysis revealed that whole-genome duplication (WGD) events and dispersed duplication events were the major mechanisms promoting the expansion of the GRAS protein family in these Rosaceae species. Furthermore, selection pressure caused by different duplication events indicates that  GRAS  genes were mainly under purifying selection during the evolution process, suggesting that strong functional restriction affected the evolution of  GRAS  genes. Analysis of gene expression patterns and qRT-PCR assays showed that  GRAS  genes were widely participating in the development of pear and that expression could be tissue-specific. In particular, further analysis indicated that  Pbr010864.1  and  Pbr024549.1  might be two important candidate genes during anthocyanin biosynthesis in pear. Our study is the first to perform a comprehensive analysis of the  GRAS  genes in pear and other Rosaceae species. These results presented here provide profitable information for understanding the process of the  GRAS  genes evolution and the possible improvement of pear fruit quality.
