Genome-wide identification of pyrabactin resistance 1-like (PYL) gene family under phytohormones and drought stresses in alfalfa (Medicago sativa).

ABSTRACT:

Background

The Pyrabactin resistance 1-like proteins (PYR/PYL/RCAR) protein plays a critical regulatory role in the ABA signal transduction pathway as a direct receptor of abscisic acid (ABA). Although PYL genes have been identified in a variety of plants, the evolution and structural characteristics of these genes in alfalfa (Medicago sativa) are largely unknown. Therefore, a comprehensive bioinformatics analysis of the PYL gene family was performed in this research.

Results

The results indicated that 41 MsPYL genes were unevenly distributed across 24 chromosomes. According to gene structure, conservative features, and phylogenetic relationships, MsPYL proteins can be divided into 6 groups, all of which have PYR/PYL/RCAR domains, and MsPYL proteins are relatively small (mol
