By deep-sequencing many accessions of cotton, we have revealed detailed genetic information and phylogeographic patterns demonstrating the diversity in the cotton genome. We have re-sequenced more than 600 accessions, including 431 accessions of G. hirsutum, 165 accessions of G. barbadense, and other species. We detected the variation among these accessions and identified genetic variation between cultivars and wild species, also between the different species. This wealth of sequence information will allows us to identify which specific gene or genome region have been selected during domestication of cotton. Understanding the location of these loci will allow us to further improve the cotton genome for agricultural improvement.
