Genome-Wide Characterization and Expression Profiling of GeBP Gene Family in Brassica rapa

The GeBP gene family, known for its GLABROUS1 enhancer-binding proteins, represents a standard transcription factor characterized by an unconventional leucine- zipper motif. The constituents of this family possess a core DNA-affinity domain. This protein is crucial for controlling plant growth and development. GeBP genes have been analyzed and defined only in some Gramineae crops, Arabidopsis, rice and soybean. However, a comprehensive examination of the role of the GeBP genes in Brassica rapa has yet to be conducted. This study used genome-wide characterization to identify twenty BrGeBP genes and accessible RNA sequencing data to evaluate each gene's expression. Based on phylogenetic research, we grouped 114 GeBP proteins from five different plant species into six groups. Generally, groupings of BrGeBP genes with comparable motifs and exon-intron distribution were conserved. The twenty BrGeBP genes were found on six of the ten B. rapa chromosomes, and one paralog showed segmental duplication. The varied protein motifs and gene structures showed that the GeBP genes had various roles in plants. The functions of BrGeBP genes are numerous and include expressions responsive to specific tissues, stress, and hormones according to cis-elements analysis. Furthermore, expression analysis using RNA sequencing revealed that the genes BrGeBP3, BrGeBP9, and BrGeBP20 showed substantially increased expression in different organs. These findings will aid in elucidating the possible roles and traits of BrGeBP genes in the B. rapa biological cycle and related species.
