Genome-wide identification, characterization, and expression analysis of the DMP gene family in Chinese cabbage (Brassica rapa ssp. pekinensis).

ABSTRACT:

Background

The DMPs (DOMAIN OF UNKNOWN FUNCTION 679 membrane proteins) constitute a plant-specific protein family that plays essential roles in reproductive development, senescence, and diverse physiological processes. Despite their importance, limited information is available on DMP genes in Chinese cabbage (Brassica rapa). To address this, we conducted a genome-wide identification and characterization of the DMP gene family in Chinese cabbage, followed by analyses of their structural features, evolutionary relationships, and expression patterns.

Results

A total of 16 BrDMP genes were identified, unevenly distributed across 10 chromosomes. Most BrDMP genes contained a single exon without introns. Evolutionary analyses revealed 3 tandem and 6 segmental duplication events, wh
