Abstract
Expression of many genes is induced during dehydration in vegetative tissues of the desiccation tolerant resurrection plantCraterostigma plantagineum. The most abundant group of desiccation-related gene products belong to the LEA (= Late Embryogenesis Abundant) proteins. Here we describe structures and expression patterns of members of group 3 and group 4Lea genes fromC. plantagineum. The most intriguing observation is the strong conservation of repeat motifs inLea genes found across divers plant species includingC. plantagineum and non-desiccation tolerant plants. This conservation of structural elements leads to speculations about evolution of desiccation tolerance in the resurrection plant.
