Background Understanding the evolutionary genetics of modern crop phenotypes has a
dual relevance to evolutionary biology and crop improvement. Modern upland cotton …

Background SNPs are the most abundant polymorphism type, and have been explored in
many crop genomic studies, including rice and maize. SNP discovery in allotetraploid cotton …

Upland cotton is a model for polyploid crop domestication and transgenic improvement.
Here we sequenced the allotetraploid Gossypium hirsutum L. acc. TM-1 genome by …

Polyploidy is an evolutionary innovation for many animals and all flowering plants, but its
impact on selection and domestication remains elusive. Here we analyze genome evolution …

The mapping of functional genes plays an important role in studies of genome structure,
function, and evolution, as well as allowing gene cloning and marker-assisted selection to …

Of the many processes that generate gene duplications, polyploidy is unique in that entire
genomes are duplicated. This process has been important in the evolution of many …

Background Cotton germplasm resources contain beneficial alleles that can be exploited to
develop germplasm adapted to emerging environmental and climate conditions. Accessions …

Recent work has demonstrated that allopolyploid speciation in plants may be associated
with non-Mendelian genomic changes in the early generations following polyploid …

Cotton is an important crop that has made significant gains in production over the last
century. Emerging pests such as the reniform nematode have threatened cotton production …

The relatives of the cottons form the first subject of discussion in this small volume based on
lectures delivered in 1954 at the North Carolina State College. Descriptions are given of the …
