Global Landscapes of the Na⁺/H⁺ Antiporter (NHX) Family Members Uncover their Potential Roles in Regulating the Rapeseed Resistance to Salt Stress.

ABSTRACT: Soil salinity is a main abiotic stress in agriculture worldwide. The Na⁺/H⁺ antiporters (NHXs) play pivotal roles in intracellular Na⁺ excretion and vacuolar Na⁺ compartmentalization, which are important for plant salt stress resistance (SSR). However, few systematic analyses of NHXs has been reported in allotetraploid rapeseed so far. Here, a total of 18 full-length NHX homologs, representing seven subgroups (NHX1-NHX8 without NHX5), were identified in the rapeseed genome (A_nA_nC_nC_n). Number variations of BnaNHXs might indicate their significantly differential roles in the regulation of rapeseed SSR. BnaNHXs were phylogenetically divided into three evolutionary clades, and the members in the same subgro
