Salinity stress is one of the prevailing abiotic stresses which results in significant losses in agricultural crop production, particularly in arid and semi-arid areas. In order to identify the key genes involved in salinity tolerance, Suaeda salsa with the capacity to adapt to high salinity levels was investigated at the transcriptome level. RNA sequencing at 0, 200, 400 and 800mM NaCl provided efficient description of gene expression profiling during the stress. However, these studies usually focus on differentially expressed gene screening, while the interaction degree between genes involved in salinity stress has not yet been investigated. For this purpose, the correlation network of 50 genes, (logFC>2 compared to the control) responding to salinity stress with 848 interactions, constructed using cystoscape software, which genes were grouped in three different clusters. The threshold of r>0.95 and P-value<0.01 was used to depict the modules. 31 genes of 50 selected genes were placed in 4 different modules, where the most number of genes was related to the red module (15 genes). Kyoto Encyclopedia of Genes and Genomes (KEGG) analysis for modules indicated that, glyoxylate and dicarboxylate metabolism was the only enriched pathway which found in the red module during the salt stress. |
