Duplicate Gene Revolution, Homoeologous Recombination, and Transcriptome Characterization in Allopolyploid Cotton

Abstract

Background: Modern allotetraploid cotton contains an “A” and “D” genome from an ancestral polyploidy event that occurred approximately 1–2 million years ago. Diploid Aand D-genome species can be compared to the Aand D-genomes found within these allotetraploids to make evolutionary inferences about polyploidy. In this paper we present a comprehensive EST… (More)
