Genome-Wide Characterization of the ADK Gene Family and Analysis of Expression Patterns Under Abiotic Stress in Beans

In plants, Adenylate Kinase (ADK) genes are essential genetic components that regulate critical processes such as growth, development and response to abiotic and biotic stress factors. In this study, genome-wide identification, bioinformatic analyses and expression profiles of ADK genes in Phaseolus vulgaris leaf tissue under drought and salt stress were investigated. As a result of the study, 7 Phvul-ADK proteins were identified and it was determined that the amino acid lengths of these proteins ranged from 239 to 597 and molecular weights ranged from 26,6 to 66,9 kDa . In addition, it was determined that the number of exons of the genes varied between 3 and 19. Phylogenetic analysis based on ADK proteins from Phaseolus vulgaris, Arabidopsis thaliana, Hordeum vulgare, Oryza sativa and Volvox carteri species revealed that the genes were divided into three different groups. In addition, Phvul-ADK-2 and Phvul-ADK-5 genes were found to show segmental duplication in the bean genome. This study is the first comprehensive genome-wide analysis of the Adenylate Kinase family in bean and highlights the important roles of the ADK gene family in plant development and stress responses. It is evaluated that the findings obtained will provide important contributions to bean breeding studies and stress tolerance research.
