Genome-wide characterization of ALDH Superfamily in Brassica rapa and enhancement of stress tolerance in heterologous hosts by BrALDH7B2 expression.

ABSTRACT: Aldehyde dehydrogenase (ALDH) carries out oxidation of toxic aldehydes using NAD⁺/NADP⁺ as cofactors. In the present study, we performed a genome-wide identification and expression analysis of genes in the ALDH gene family in Brassica rapa. A total of 23 ALDH genes in the superfamily have been identified according to the classification of ALDH Gene Nomenclature Committee (AGNC). They were distributed unevenly across all 10 chromosomes. All the 23 Brassica rapa ALDH (BrALDH) genes exhibited varied expression patterns during treatments with abiotic stress inducers and hormonal treatments. The relative expression profiles of ALDH genes in B. rapa showed that they are predominantly expressed in leaves and stem suggesting their function in the vegetative tissues. BrALDH7B2
