Genome-wide identification and expression analysis of the GARP superfamily in response to abiotic stresses in alfalfa (Medicago sativa L.).

ABSTRACT:

Background

Alfalfa (Medicago sativa L.), a vital forage legume, faces significant productivity limitations from abiotic stresses. The GARP superfamily, characterized by a conserved B-motif domain, is crucial for regulating plant growth, development, and stress reponses. Despite extensive studies in model plants, the systematic characterization of GARP genes in alfalfa remains unexplored.

Results

In this study, a total of 51 GARP genes (referred to as MsGARPs) were identified from the alfalfa reference genome (Zhongmu No. 1) and renamed on the basis of their chromosomal distribution (MsARR-B1 to MsARR-B20 and MsGLK1 to MsGLK31). These MsGARP proteins were phylogenetically classified into 5 subfamilies, ARR-B, GLK, NIGT1/HRS1/HHO, PHR1/PHL1 and KAN.​ Gene structure and conserv
