Abstract excerpt

Duplicate loci offer a very powerful system for understanding the complicated genome structure and adaptive evolution of a gene family. In this study, the genetic variation at paralogs AtHVA22d and AtHVA22e, members of an ABA- and stress-inducible gene family, is examined in the selfing Arabidopsis thaliana. Population genetic analysis indicates contrasting levels of nucleotide diversity at overall exon sequence...
