摘要：Aldehyde dehydrogenase (ALDH) superfamily, comprising enzymes dependent on NAD+ or NADP+, plays an important role in controlling plant growth and development, as well as in responsing to phytohormone and environmental stress. These enzymes possess the ability to prevent toxic effects of aldehydes by converting them into their corresponding carboxylic acids. However, the potential function of ALDH genes in moso bamboo (Phyllostachys edulis) remains largely unknown. In this study, the ALDH gene superfamily in moso bamboo was analyzed through genome-wide screening, the evolutionary relationship of expansion genes was conducted. Tissue-specific expression patterns of ALDH genes were observed in 26 different tissues. Plant hormone and environmental stress responsive cis-elements were identified in the promoter of ALDH genes, which were supported by public databases data on the expression patterns under various abiotic stresses and hormone treatments. ALDH activity was increased in moso bamboo seedlings exposed to drought, compared to control condition. Furthermore, PeALDH2B2 was found to physically interact with PeGPB1 in response to drought. Overall, the study provides a comprehensive analysis of the ALDH family in moso bamboo and contributes to our understanding of the function of ALDH genes in growth, development, and adaptation to drought stresses.
