Genome-wide analysis of the pleiotropic drug resistance (PDR) gene family and putative PDR specific miRNAs: deciphering their functions in development processes and varied stresses in Triticum aestivum L.

ABSTRACT:

Background

The pleiotropic drug resistance (PDR) transporter stands out as one of the largest subfamilies within ABC transporters. These transporters play crucial roles in a multitude of biological processes, including detoxification, phytohormone transportation, stomatal movement, the translocation of various secondary metabolites, tolerance to heavy metal and adaptation to the diverse stress conditions. However, the structural and functional characterization of PDR gene family members in wheat has yet to be fully elucidated.

Results

In this investigation, we identified 66 TaPDR genes in the genome of wheat. The subsequent phylogenetic tree revealed that the genes clustered into four subfamilies. Chromosomal mapping unveiled the dispersal of 66 TaPDR genes across 17 wheat c
