AcCOMT9 positive regulates Cd tolerance in kiwifruit by modulating heavy metal transport and antioxidant capacity.
Soil cadmium (Cd) contamination poses a severe threat to crop productivity and food safety. Melatonin, a potent endogenous antioxidant and signaling molecule, plays a pivotal role in mitigating plant abiotic stresses, including Cd stress. However, the molecular mechanisms underlying melatonin-mediated Cd tolerance in k...
