Genome-wide identification and expression analysis of the MBD gene family in Broomcorn millet (Panicum miliaceum) and its response to abiotic stress.

ABSTRACT:

Background

The MBD gene family participates in key biological processes such as plant growth and development, hormonal signaling transduction, and stress response through epigenetic regulatory mechanisms. Broomcorn millet, an important drought-tolerant, barren-tolerant, and photoperiod-sensitive miscellaneous grain in northern China, the characteristics and functions of its MBD genes remain unclear.

Results

In this study, 11 members of the MBD gene family were identified. Collinearity analysis revealed that the PmMBD gene family primarily expanded through fragment duplication, with some members showing collinearity to genes in rice, wheat, and maize. The promoter regions of PmMBDs contain various cis-regulatory elements associated with developmental regulation, hormone respo
