Plant-specific GRAS transcription factors regulate various biological processes in plant growth, development and stress responses. However, this important gene family was not fully characterized in pepper ( Capsicum annuum  L.), an economically important vegetable crop. Here, a total of 50 CaGRAS members were identified in pepper genome and renamed by their respective chromosomal distribution. Genomic organization revealed that most  CaGRAS  genes (84%) have no intron. Phylogenetic analysis divided pepper CaGRAS members into 10 subfamilies, with each having distinct conserved domains and functions. For the expansion of the  GRAS  genes in pepper, segmental duplication contributed more than tandem duplication did. Gene expression analysis in various tissues demonstrated that most of  CaGRAS  genes exhibited a tissue- and development stage-specific expression pattern, uncovering their potential functions in pepper growth and development. Moreover, 21  CaGRAS  genes were differentially expressed under cold, drought, salt and gibberellin acid (GA) treatments, indicating that they may implicated in plant response to abiotic stress. Notably, GA responsive  cis -elements were detected in the promoter regions of the majority of  CaGRAS  genes, suggesting that CaGRAS may involve in signal cross-talking. The first comprehensive analysis of GRAS gene family in pepper genome by this study provide insights into understanding the GRAS-mediated regulation network, benefiting the genetic improvements in pepper and some other relative plants.
