The RcDREB1E‐RcMYB28 module improves drought tolerance in Rosa chinensis via RcLAR / RcCORA1 ‐mediated proanthocyanidin biosynthesis and stress responses
SUMMARY Drought is widely recognized as one of the most severe abiotic stresses limiting plant growth and productivity. Proanthocyanidins (PAs), as key functional secondary metabolites, are central to enhancing plant tolerance to abiotic stresses. Nevertheless, the specific mechanisms underlying PA‐mediated drought res...
