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

This study provides the first comprehensive characterization of the DMP gene family in Chinese cabbage. Our findings not only advance understanding of BrDMP gene functions but also identify BrDMP9A and BrDMP9B as strong candidates for developing DMP-based haploid inducer lines, offering direct applications for accelerating doubled-haploid breeding in Brassica crops.
