Technical Abstract: Improved drought tolerance of crop plants is vital to the sustainability of agriculture. The principal aim of this collaborative project was to discover drought-stress response genes in cotton. We have identified a collection of putative drought-stress responsive candidate genes by in silico screening of 3593 ESTs generated from a drought-stressed and irrigated cotton boll libraries. A subset of these candidate stress response genes were evaluated for genome specificity and mapped onto the cotton genetic map. Several candidate genes colocalized with phenotypes (QTLs) known to be responsible for variation in drought-stress response. Merging gene expression data, genetic mapping information, and physiological data is a significant step towards understanding the genetics controlling the physiological responses that affect production and quality under adverse conditions.
