Genome-wide identification and analysis of SmRR gene family in eggplant (Solanum melongena L.) and their response to abiotic stress and auxin.

ABSTRACT:

Background

Response regulator proteins (RRs) are integral components of two-component regulatory systems and play critical roles in cytokinin signaling, regulation of plant growth and development, and responses to biotic and abiotic stresses. While numerous RR families have been identified, comprehensive characterization and functional studies of RR genes in eggplant have not been reported.

Results

In this study, we conducted a genome-wide identification and analysis of RR genes in eggplant. Through Blastp and HMM methods, a total of 32 RRs were identified. Phylogenetic analysis classified all RRs into three categories: type-A, type-B RRs, and PRRs (Pseudo-RRs), while no type-C genes were detected. Gene structure and motif analysis demonstrated similarities within each type.
