Further Information

Gossypium as a model for polyploidy, evolutionary genomics and development. There are a number of characteristics that render cotton an excellent model for the proposed studies. These include: (1) the nature of the trait of most interest (fiber), which is single-celled, morphologically diverse among species and genotypes, but developmentally less challenging to study than other plant traits; (2) parallel domestication of two allopolyploids, G. hirsutum and G. barbadense; (3) a well-understood evolutionary history, providing a grounded understanding of antecedent and descendant conditions in a temporal context; (4) the existence of natural and cultivated polyploids that are sufficiently old for adaptive evolution to have taken place, as well as living models of the diploid progenitors; (5) an extensive set of genomic tools and resources to facilitate sophisticated experiments (many developed under prior NSF support), including extensive genetic maps, ESTs, BAC resources and microarrays; and (6) a US Department of Energy Joint Genome Institute "Community Sequencing Program" (led by Paterson), nearing completion, to provide 500 Mb (0.6x) genome sequence for G. raimondii (D genome). The cotton research community has recently converged on a sequencing strategy. Thus, these are exciting times to be involved in cotton research.
