Citation: Yu, J., Kohel, R.J. 2001. Cotton genome research in the United States. In: Jenkins, J.N., Saha, S., editors. Genetic Improvement of Cotton: Emerging Technologies. Enfield, NH: Science Publishers, Inc. p. 103-121.

Interpretive Summary: Contemporary genomic technologies are of great interest to plant geneticists to analyze the structure, function, and evolution of DNA to gain knowledge and resources for genetic improvement of crop plants. Cotton is the world's leading fiber crop and the second most important oilseed crop. This book chapter reviews and discusses the composition of cotton genomes in the genus Gossypium L., the status of genomic research and applications in the United States, and future perspectives in this area. In general, cotton genomic research is behind those of other major crops such as maize, soybean, and wheat because of shortage of essential public infrastructure and tools. However, several U.S. locations and groups have been conducting research on cotton genomics including the development of DNA markers for genetic mapping, genomic localization of major genes and quantitative trait loci (QTLs) of economic or agronomic importance, establishment of cotton genome databases. The genomic resources and information have been applied to germplasm characterization, marker-assisted breeding, and map-based gene cloning. Future efforts in cotton genome research include the development of more portable DNA markers, integrative physical and genetic mapping, functional and comparative analysis of the cotton genome, and bridging cotton with other model plants.
