Transcriptomic Analysis of Salicylic Acid Promoting Seed Germination of Melon under Salt Stress

This study investigated how salicylic acid (SA) mediates the response of melon (Cucumis melo) seeds to salt stress using physiological and transcriptomic methods. The effects SA on antioxidant enzymes, osmoregulatory substances, transcriptome under were sodium chloride (NaCl, 100 mmol·L−1) as stimulant + NaCl (0.25 mmol·L−1 alleviation treatment. results showed that positively influences tolerance by increasing activity superoxide dismutase (SOD) catalase (CAT) while decreasing proline content (Pro). Differentially expressed genes (DEGs) identified data analysis, which 2958 up-regulated, 2157 down-regulated. These mainly involved in mitogen-activated protein kinase (MAPK) signaling pathway plant hormone signal transduction, lipid metabolism (linoleic α-linolenic fatty metabolism), biosynthesis secondary metabolites (phenylpropanoid flavonoid biosynthesis), related pathways. Further analysis revealed might alleviate initiating a series pathways stress, participating lignin improve cell wall stability, regulating lipoxygenase (LOX) genes. provide valuable information new strategies for future resistance cultivation high yield.
