Project description:Peanut (Arachis hypogaea L.) is a prominent legume and oilseed crop cultivated globally for its economic significance and nutritional value, as it is rich in fat, protein, carbohydrates, and micronutrients. To meet the growing demand for edible oil and protein, it is necessary to further expand the cultivation area and improve the seed yield of peanut. Salinized land represents a potential resource for expanding peanut cultivation. However, most peanut genotypes are sensitive to salt stress, and soil salinity severely limits peanut productivity. Therefore, enhancing salt tolerance in peanut is essential. This study aimed to identify genes associated with salt stress through transcriptome analysis, thereby providing a genetic basis for improving salt tolerance in peanut. To identify salt stress-related genes, two cultivars—Huayu 33 (HY33, salt-tolerant) and Huayu 9115 (HY9115, salt-sensitive)—were subjected to salt stress treatment. Plants of HY33 and HY9115 were collected at 0 h, 3 h, 12 h, 24 h, and 48 h after salt treatment for transcriptome sequencing. Using the RNA sequencing data, numerous differentially expressed genes were identified as candidates for further functional study. This study provides extensive gene expression data for identifying key genes related to salt stress and establishes a basis for elucidating the underlying regulatory mechanisms. These findings can contribute to enhancing the salt tolerance of peanut through molecular breeding.
