Apples are one of the world's four most economically significant fruits, and drought stress is an important factor limiting development global apple industry. Here, we demonstrate that a proline-rich protein (PRP), MdPRP6, regulating long-term adaptation plants. Suppression MdPRP6 in plants (MdPRP6-Ri) enhances their to moderate conditions, as indicated by significantly higher biomass relative water content (RWC) compared with wild-type (WT) Under stress, net photosynthetic rate (Pn), intercellular CO2 concentration (Ci), stomatal conductance (Gs), transpiration (Tr) were higher, photosystem II (PSII) damage was lower MdPRP6-Ri than WT increased activity antioxidant enzymes, including superoxide dismutase (SOD), peroxidase (POD), catalase (CAT), which reduced oxidative leaves under stress. The openings larger those plants; WUEI WUEL thus We also found suppression wax leaf epidermis, limits evaporation caused non-stomatal factors In sum, our findings suggest negatively affects plants, possibly modulating both loss.
