Genome-wide identification and expression pattern analysis under drought stress of PHD family genes in alfalfa (Medicago sativa).

ABSTRACT:

Background

Alfalfa (Medicago sativa) is a perennial high-quality legume forage widely cultivated worldwide, but drought stress severely restrict its growth and development. Plant homeodomain finger (PHD) family genes are a type of zinc finger transcription factors widely distributed in eukaryotes. They act as histone code identifier to regulate the expression of downstream genes and play important biological roles in plant growth, development, and stress response. However, information about the PHD family genes in alfalfa remains limited at present.

Results

We identified 56 MsPHD genes containing 67 PHD domains in the alfalfa, and these genes were unevenly distributed on 8 chromosomes of alfalfa. There are 9 pairs of gene fragment duplicates in the MsPHD family. The 56 MsPHD
