Abstract
The availability of a large number of molecular markers is a prerequisite, especially in cotton, for identifying a sufficient number of informative markers for mapping and genetic analysis. Despite the global importance of the cotton crop, few informative microsatellite markers are available, primarily because of the cost associated with their development. This report describes an improved and cost-effective strategy for developing microsatellite markers. Genomic DNA was randomly sheared with nitrogen gas to obtain unbiased representation of the genome, and the fragments containing microsatellites were captured by using biotinylated oligos and streptavidin-based recovery. Six libraries enriched for 14 microsatellite motifs were constructed and screened. Nearly 4900 simple sequence repeat (SSR)-containing sequences were identified, leading to the development of more than 1200 markers in a small amount of time.
