| Tolerance to drought in plants is not a simple trait, but a complex of mechanisms working in combination to avoid or to resist water deficit. Genotypes that differ in tolerance to water deficit may show qualitative and quantitative differences in gene expression when submitted to drought periods. Four cotton (Gossypium hirsutum L.) genotypes (Siokra L-23, Stoneville 506, CS 50 and T-1521) with contrasting responses to water deficit stress were studied using the Differential Display (DD) technique to identify and isolate genes which may differ among them. Fifty-two cDNA fragments differentially expressed during water deficit were isolated, cloned and sequenced. Search of gene bank databases showed that two cDNA clones, A12B15-6 and A12B13-1, have high... |
