Abstract excerpt

Two allelic Arabidopsis mutants, leaf wilting 2-1 and leaf wilting 2-2 (lew2-1 and lew2-2 ), were isolated in a screen for plants with altered drought stress responses. The mutants were more tolerant to drought stress as well as to NaCl, mannitol and other osmotic stresses. lew2 mutant plants accumulated more abscisic acid (ABA), proline and soluble sugars than the wild type. The expression of a stress-inducible...
