A preliminary analysis of genome structure and composition in Gossypium hirsutum.

ABSTRACT:

Background

Upland cotton has the highest yield, and accounts for > 95% of world cotton production. Decoding upland cotton genomes will undoubtedly provide the ultimate reference and resource for structural, functional, and evolutionary studies of the species. Here, we employed GeneTrek and BAC tagging information approaches to predict the general composition and structure of the allotetraploid cotton genome.

Results

142 BAC sequences from Gossypium hirsutum cv. Maxxa were downloaded http://www.ncbi.nlm.nih.gov and confirmed. These BAC sequence analysis revealed that the tetraploid cotton genome contains over 70,000 candidate genes with duplicated gene copies in homoeologous A- and D-subgenome regions. Gene distribution is uneven, with gene-rich and gene-free regions of the g
