The transcriptome datasets

Alfalfa (Medicago sativa L.) is widely cultivated and planted worldwide due to its high yield, good nutritional quality, and wide adaptability. Salt stress is one of the most important abiotic stresses that lead to reduced yield and growth inhibition in Alfalfa. Gibberellin (GA) is an endogenous hormone synthesized by plants. It is known that Gibberellin A3 (GA3) can improve the salt tolerance of Alfalfa by remodeling ion homeostasis, regulating osmotic pressure synthesis and activating antioxidant enzymes. In addition, GA3 can also regulate the synthesis and degradation of various bioactive molecules in plants and participate in the expression of stress related genes with the synergy and antagonism between GA3 and other plant hormones. Therefore, it plays an important role in plant stress resistance. However, the genetic and molecular mechanisms mediating the salt tolerance of Alfalfa still need to be better understood. In order to investigate the key genes and pathways mediating the effect of GA3 on alleviating salt stress, we conducted physiological and biochemical analysis and transcriptomic analysis on Alfalfa seedlings.
