Genome-wide characterization and expression analysis of GRAS gene family in pepper (Capsicum annuum L.).

ABSTRACT: 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
