In Silico Analysis of SOS Family in Areca palm (Areca catechu. L)

Abstract

Abstract The salt-overly sensitive ( SOS) gene is a signaling gene that helps plants to respond to high salinity stress. It is activated when cells are exposed to high levels of sodium ions, and it leads to a number of changes in gene expression that help the plant cope with high salinity stress. However, The SOS gene in Arecha palm has not been studied, despite being present in various plant species. We have identified 10 members of the AcatSOS family of genes, which are dispersed randomly over 5 chromosomes in the genome of Areca catechu. Using the phylogenetic analysis of 10 AcatSOS genes and two additional species rice and Arabidopsis—the tree is divided into 5 subfamilies: Group 1, Group 2, Group 3, Group 4 and Group 5. Each gene in the AcatSOS family was identified on its physiochemical properties. The plastid and vacuole contain most of the localization signals. Furthermore, there were numerous cis-acting areas and light-responsive elements in the promoter sequences of the AcatSOS genes. After the Areca palm genome was sequenced, segmental and tendom duplications were discovered, providing evidence of a major driving force in the evolution of the AcatSOS gene family. Areca palms share numerous genes, in terms of orthologous relationships, with other monocotyledonous plants because of their evolutionary affinity and related heritage. The development of the leaf, endocarp, and epicarp is regulated by the AcatSOS genes, according to circular heat. AcatSOS-4, AcatSOS-6 and AcatSOS-8 are highly regulated in plants. Genome-wide characterization of the SOS gene expression patterns has revealed that the expression of these genes is regulated in a complex manner. It is influenced by several factors, including the level of salinity stress, the developmental stage of the plant, and the tissue type.
