ACTINs are key structural proteins in plants, which form the actin cytoskeleton and are engaged in numerous routine cellular processes. Meanwhile, , recognized as a housekeeping gene, has not yet been thoroughly investigated in . The current research has led to the detection of 69 actin genes in , which were organized into six distinct subfamilies on the basis of phylogenetic relationships. Functional enrichment analysis, along with the construction of protein interaction networks, suggested that s play roles in Preserving cell morphology and facilitating cytoplasmic movement, plant development, and adaptive responses to environmental stress. Moreover, the genes presented a wide range of expression levels among different tissues, whereas the majority experienced a substantial increase in expression when subjected to various abiotic stresses, demonstrating a pronounced sensitivity to abiotic factors. Furthermore, association mapping analysis indicated that some s potentially affected certain key agronomic traits. Overall, our research deepens the knowledge of genes, promotes the cultivation of improved strains, and lays the groundwork for subsequent functional research.
