Peanut (Arachis hypogaea L.) is an important oilseed crop worldwide. However, soil salinization becomes one of the main limiting factors peanut production. Therefore, developing salt-tolerant varieties and understanding molecular mechanisms salt tolerance to protect yield in saline areas. In this study, we selected four with contrasting response challenges T1 T2 being S1 S2 susceptible. High-throughput RNA sequencing resulted more than 314.63 Gb clean data from 48 samples. We identified 12,057 new genes, 7,971of which have functional annotations. KEGG pathway enrichment analysis uniquely expressed genes revealed that upregulated root are involved MAPK signaling pathway, fatty acid degradation, glycolysis/gluconeogenesis, shoot were plant hormone signal transduction pathway.
