Sequencing and comparative analyses of polyploid cotton genomes

Cotton not only provides the largest renewal source of textile fiber, but also is a model for studying fiber cell differentiation, cellulose biosynthesis, as well as polyploidy and its impact on genome evolution and crop domestication. In this report, we will update the progress of collective efforts on generating reference-grade sequences of the tetraploid cotton genomes and analyzing the structure and function of these genomes using multi-dimensional and integrated approaches.
