Abstract

<italic>Triticum aestivum</italic> RNA-Seq differentially expressed genes (DEGs) salinity stress molecular mechanisms
Salt tolerance is a critical trait for plant survival and productivity in saline environments. Development of salt tolerant crops is a practical strategy for addressing soil salinity issues. In this study, RNA-Seq analysis was performed using two wheat cultivars with contrasting salt tolerance (Neixiang188, tolerant and Barra, sensitive) at 6 h and 24 h after salinity treatment to determine the genetic variations reflected in the RNA expression patterns and identify key genes associated with salt tolerance. Our results revealed that there were 2983 upregulated and 1091 downregulated differentially expressed genes (DEGs), which were found in common in the two accessions. Meanwhile, 529 salt tolerant associated DEGs were subjected to GO function annotation, KEGG enrichment, and protein–protein interaction (PPI) network prediction. Finally, a theoretical framework outlining the salt tolerance mechanisms of Neixiang188 was proposed. It can be inferred that Neixiang188 possesses superior ion homeostasis, ROS detoxification, and osmotic adjustment abilities compared to Barra when subjected to saline stress. The present research sheds light on the genetic foundation of salt tolerance in wheat and offers candidate genes for genetic manipulation. Our research insights enhance the comprehension of the molecular mechanisms underlying salt stress responses and could guide future breeding efforts for improving salt tolerance in crops.
