Over-expression of different aldehyde dehydrogenase genes in Arabidopsis thaliana confers tolerance to abiotic stress and protects plants against lipid peroxidation and oxidative stress.

Aldehyde dehydrogenases (ALDHs) play a major role in the detoxification processes of aldehydes generated in plants when exposed to abiotic stress. In previous studies, we have shown that the Arabidopsis thaliana ALDH3I1 gene is transcriptionally activated by abiotic stress, and over-expression of the ALDH3I1 gene confers stress tolerance in transgenic plants. The A.

Identification of a dehydration and ABA-responsive promoter regulon and isolation of corresponding DNA binding proteins for the group 4 LEA gene CpC2 from C. plantagineum.

The resurrection plant Craterostigma plantagineum (Scrophulariaceae) is used as a model system to investigate the molecular and biochemical basis of desiccation tolerance. Genes which contribute to desiccation tolerance are expressed during dehydration of this plant. One of the dehydration-induced genes is CpC2, a group 4 LEA gene.
