Genome-Wide Identification of the Gossypium hirsutum NHX Genes Reveals that the Endosomal-Type GhNHX4A is Critical for the Salt Tolerance of Cotton.

ABSTRACT: Soil salinization, which is primarily due to excessive Na⁺ levels, is a major abiotic stress adversely affecting plant growth and development. The Na⁺/H⁺ antiporter (NHX) is a transmembrane protein mediating the transport of Na⁺ or K⁺ and H⁺ across the membrane to modulate the ionic balance of plants in response to salt stress. Research regarding NHXs has mainly focused on the vacuolar-type NHX family members. However, the biological functions of the endosomal-type NHXs remain relatively uncharacterized. In this study, 22 NHX family members were identified in Gossypium hirsutum. A phylogenetic analysis divided the GhNHX genes into two categories, with 18 and 4 in the vacuolar and endosomal groups, respectively.
