Cotton has been collected in Brazil for decades for its conservation, evaluation, and the use of its genetic resources. Gossypium mustelinum is an allotetraploid cotton species that only occurs in Brazil, and little is known about its genetic potential for improvement. However, the species is threatened by habitat fragmentation and interspecific hybridization with exotic species of cotton. In this study, we investigated the rate of natural hybridization in two populations of G. mustelinum in Bahia, Brazil, with G. hirsutum and G.

Construction and characterization of a bacterial artificial chromosome library for the allotetraploid Gossypium tomentosum

F. Liu, Wang, Y. H., Gao, H. Y., Wang, C. Y., Zhou, Z. L., Cai, X. Y., Wang, X. X., Zhang, Z. S., and Wang, K. B., Construction and characterization of a bacterial artificial chromosome library for the allotetraploid Gossypium tomentosum, vol. 14, pp. 16975-16980, 2015.

Gossypium tomentosum is a wild allotetraploid species with the (AD)5 genome. It is characterized by many useful traits including finer fiber fineness, drought tolerance, and Fusarium and Verticillium resistance. We constructed the first bacterial artificial chromosome library for Gossypium tomentosum. With high quality and broad coverage, this library includes 200,832 clones, with an average insert size of about 122 kb and fewer than 3% empty clones.
