Transcriptome Analysis Reveals Differences in Molecular Mechanisms Between Salt-Tolerant and Salt-Sensitive Rice (<i>Oryza sativa</i> L.) Varieties Under Salt Stress.

ABSTRACT: To elucidate the molecular mechanisms underlying salt tolerance in rice (Oryza sativa L.), this study investigated differential transcriptional responses during the tillering stage. Salt-tolerant (N14) and salt-sensitive (N6) varieties were subjected to 0.3% and 0.6% NaCl treatments for 72 h, and their transcriptomes were analyzed via RNA-Seq. The results revealed distinct response strategies: 372 differentially expressed genes (DEGs) were identified in N14 and 393 in N6, with only 17 genes responding similarly. Gene Ontology (GO) analysis showed the tolerant N14 activated protein phosphorylation and lipid transport, primarily in the membrane and extracellular regions (e.g., ATP binding), whereas the sensitive N6 activated photosynthesis and protein folding, localized to chloroplast
