摘要：

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