Abstract
- Planting economic crops in soil with salt imbalances can improve land use efficiency. Hemp, which can be planted in low-salinity soil, is a crop with a very high economic value. To reveal the salt tolerance mechanism of hemp, the leaves of Longma #3 and #9 were collected at 0, 2, 4, and 6 days after salt stress in this study, and transcriptome and metabolome joint analysis were performed. The concentration of glutamic acid, succinic acid and gamma-aminobutyric acid (GABA) was 12 times that of the control group. The large increase in succinic acid led to the maintenance of peroxidase and superoxide dismutase levels at normal values and a decrease in H2O2 and catalase. The enriched KEGG pathway citrate cycle (TCA cycle) contains the metabolic regulation of succinic acid. Succinic acid was positively correlated with the MAPK gene. The MAPK pathway is a key pathway of plant tolerance in a high-salt environment. This study provides a reference for research on NaCl tolerance in plants and can also provide an important reference for the cultivation of NaCl-tolerant hemp varieties. [ABSTRACT FROM AUTHOR]
