Selective histories of poplar protease inhibitors: elevated polymorphism, purifying selection, and positive selection driving divergence of recent duplicates.

Abstract excerpt

To further our understanding of plant defense evolution and the consistency of selection at the nucleotide level we analysed polymorphism data from five protease inhibitor (PI) genes in Populus balsamifera. We compared diversity at the five PI genes to diversity at nondefense loci in both range-wide samples as well as in two subpopulations, one from the northern edge of the species range and one from the southern...
