The rangeland shrub Atriplex canescens (saltbush) is extremely drought-tolerant and is capable of growing at water potentials below {minus}40 bar. To discover the molecular basis of this tolerance, the authors have isolated a number of cDNA clones of drought-stress induced genes. Analysis of the nucleotide sequence and expression of these genes in different tissues and in response to different stresses reveals the diversity of the stress response. Members of a drought-induced, multi-gene family, have been sequenced. Although 95% homologous, non-conservative substitutions result in proteins of different tertiary structure. Additionally, the genes are expressed through a number of mature forms of mRNA which may arise by alternative RNA processing.
