Towards Sequencing Cotton (Gossypium) Genomes. Plant Physiology. 145:1303-1310.
Interpretive Summary: Advances in technologies resulting from sequencing all the genes comprising the human genome have led to strategies for sequencing plant genomes. Advances in human health care have resulted directly from human genome sequencing efforts and the expectation is that this technology will have a similar impact on crop improvement. Genome sequencing generates a database listing the sequence of nucleotides (components of DNA) present in genes, identification of regions between genes, and the arrangement of genes within a chromosome. The first examples of plants whose genomes were sequenced, Arabidopsis and rice, were quickly followed by other model plants such as the moss Physcomitrella, crop plants such as Medicago, and trees such as Populus. As genomes become larger and more complex, however, there are many technical problems associated with assembling short fragments into a comprehensive genome database. Cotton, a member of the genus Gossypium, represents a special challenge for genome sequencing since each cell contains genes from two genomes that combined to form the fiber-bearing plant grown for its textile fiber. In this manuscript, an international consortium of scientists from 28 different research laboratories has developed a plan that addresses the advantages and complexities of cotton genome sequencing.
Technical Abstract: Despite rapidly decreasing costs and innovative technologies, sequencing of angiosperm genomes is not yet undertaken lightly. Generating larger amounts of sequence data more quickly does not address the difficulties of sequencing and assembling complex genomes de novo. The cotton genomes represent a challenging case. To this end, a coalition of cotton genome scientists has developed a strategy for sequencing the cotton genomes, which will vastly expand opportunities for cotton research and improvement worldwide.
