Genome-wide identification and expression analysis of the NHX gene family under salt stress in wheat (Triticum aestivum L).

ABSTRACT: Salt stress affects plant growth and development, resulting in the loss of crop yield across the world, and sodium-proton antiporters (NHXs) are one of the genes known to promote salt tolerance in transgenic plants. In this study, we conducted a comprehensive genome-wide analysis and expression profile of NHX genes in wheat under salinity stress. We identified 30 TaNHX genes in wheat based on the Na⁺/H⁺ exchanger domain, with all genes containing an amiloride motif except one, a known for inhibiting Na⁺ ions in plants. Phylogenetic analysis classified these genes into three classes with subfamilies: 12 were localized in vacuoles, while 18 were in the endoplasmic reticulum and plasma membrane. Promoter analysis revealed stress-related cis
