Diethyl aminoethyl hexanoate ameliorates salt tolerance associated with ion transport, osmotic adjustment, and metabolite reprograming in white clover

The DA-6 significantly up-regulated transcript levels of multiple genes associated with increased Na⁺ compartmentalization in vacuoles and Na⁺ sequestration in roots to reduce Na⁺ transport to photosynthetic organs, thereby maintaining Na⁺ homeostasis under salt stress. The accumulation of many organic metabolites induced by the DA-6 could be attributed to enhanced cell wall and membrane structural stability and functionality, OA, antioxidant defense, and downstream signal transduction in leaves under salt stress. The present study provides a deep insight about the synergistic role of DA-6 in salt tolerance of white clover.
