Distinct patterns of natural selection in Na⁺/H⁺ antiporter genes in Populus euphratica and Populus pruinosa.

ABSTRACT: Salt tolerance genes constitute an important class of loci in plant genomes. Little is known about the extent to which natural selection in saline environments has acted upon these loci, and what types of nucleotide diversity such selection has given rise to. Here, we surveyed genetic diversity in three types of Na⁺/H⁺ antiporter gene (SOS, NhaD, and NHX, belonging to the cation/proton antiporter 1 family), which have well-characterized essential roles in plant salt tolerance. Ten Na⁺/H⁺ antiporter genes and 16 neutral loci randomly selected as controls were sequenced from 17 accessions of two closely related members of the genus Populus, Populus euphratica and Populus pruinosa, section Turanga<
