[摘要]：Aldehyde dehydrogenases (ALDHs) are members of NAD(P)(+)-dependent protein superfamily that catalyze the oxidation of a wide range of endogenous and exogenous highly reactive aliphatic and aromatic aldehyde molecules to their corresponding non toxic carboxylic adds. Research evidence has shown that ALDHs represent a promising class of genes to improve growth development, seed storage and environmental stress adaptation in higher plants. The recently completed genome sequences of several plant species have resulted in the identification of a large number of ALDH genes, most of which still need to be functionally characterized. In this paper, we identify members of the ALDH gene superfamily in soybean genome, and provide a unified nomenclature for the entire soybean ALDH gene families. The soybean genome contains 18 unique ALDH sequences encoding members of five ALDH families involved in a wide range of metabolic and molecular detoxification pathways. In addition, we describe the biochemical requirements and cellular metabolic pathways of selected members of ALDHs in soybean responses to environmental stress conditions.
