Genome-wide identification and drought-responsive root expression profiling of the <i>VQ</i> gene family in proso millet (<i>Panicum miliaceum</i> L.).

ABSTRACT:

Background

Proso millet (Panicum miliaceum L.) is a drought-tolerant cereal crop cultivated in arid and semi-arid regions. VQ proteins, a class of plant-specific proteins characterized by a conserved VQ motif (FxxxVQxxTG), are known to play critical roles in plant responses to abiotic stress. To elucidate the genetic basis of drought tolerance in proso millet, a genome-wide identification and characterization of the VQ gene family was undertaken.

Methods

This study involved the identification of all VQ family members from the proso millet genome, followed by comprehensive analyses including chromosomal localization, phylogenetic relationships, gene structure, conserved motifs, collinearity, and promoter cis-acting elements. Expression profiling wa
