Résumé

Unlabelled - WNK kinases are a unique class of serine/threonine protein kinases that lack a conserved catalytic lysine residue in the kinase domain, hence the name WNK (with no K, i.e., lysine). WNK kinases are involved in various physiological processes in plants, such as circadian rhythm, flowering time, and stress responses. In this study, we identified 26 genes in soybean and analyzed their phylogenetic relationships, gene structures, chromosomal distribution, -regulatory elements, expression patterns, and conserved protein motifs. The soybean genes were unevenly distributed on 15 chromosomes and underwent 21 segmental duplication events during evolution. We detected 14 types of -regulatory elements in the promoters of the genes, indicating their potential involvement in different signaling pathways. The transcriptome database revealed tissue-specific and salt stress-responsive expression of genes in soybean, the second of which was confirmed by salt treatments and qRT-PCR analysis. We found that most genes were significantly up-regulated by salt stress within 3 h in both roots and leaves, except for , which showed a distinct expression pattern. Our findings provide valuable insights into the molecular characteristics and evolutionary history of the soybean gene family and lay a foundation for further analysis of gene functions in soybean.
