The expression profiles of transcripts from leaves of different Phaseolus species under drought stress were compared in order to ascertain whether changes in their expression in Phaseolus spp. are part of a general or a species specific response to drought. Relative gene expression analysis using quantitative PCR were carried out in P. coccineus, P. lunatus and P. acutifolius for 13 transcripts previously identified as up- or down-regulated in leaves of P. vulgaris. The mode of expression was found consistent within Phaseolus spp., despite the fact that the four species differ in their responses to drought at the physiological and morphological levels. The results suggest that this is a common feature of the response of Phaseolus spp.
