Abstract

Background: Aldehyde dehydrogenase (ALDH) genes constitute an important family of supergenes that play key roles in synthesizing various biomolecules and maintaining cellular homeostasis by catalyzing the oxidation of aldehyde products. With climate change increasing the exposure of plants to abiotic stresses such as salt and drought, ALDH genes have been identified as important contributors to stress tolerance. In particular, they help to reduce stress-induced lipid peroxidation. Objectives: This study aims to identify and characterize members of the ALDH supergene family in Phaseolus vulgaris through a genome-wide bioinformatic analysis and investigate their role in response to abiotic stressors such as drought and salt stress. Methods: Genome-wide identification of 26 ALDH genes in P. vulgaris was performed using bioinformatics tools. The identified ALDH proteins were analyzed for molecular weight, amino acid number, and exon number. Phylogenetic analysis was performed to classify P. vulgaris, Arabidopsis thaliana, and Glycine max ALDH proteins into different groups. Strong links between these genes and functions related to growth, development, stress responses, and hormone signaling were identified by cis-element analysis in promoter regions. In silico expression, analysis was performed to assess gene expression levels in different plant tissues. Results: RT-qPCR results showed that the expression of ALDH genes was significantly altered under drought and salt stress in beans. This study provides a comprehensive characterization of the ALDH supergene family in P. vulgaris, highlighting their potential role in abiotic stress tolerance. Conclusion: These findings provide a basis for future research on the functional roles of ALDH genes in enhancing plant resistance to environmental stressors.
