520 |a The aerial parts of apple are protected against environmental stress by cuticular wax. Although it has been suggested that several long-chain acyl-CoA synthetases are involved in wax biosynthesis, the molecular pathway of apple cuticular wax biosynthesis remains unclear. In this study, an MdLACS4 protein with long-chain acyl-CoA synthetase activity was isolated from apple. The MdLACS4 gene was highly expressed in pericarp, stem, and mature leaf tissues. Ectopic expression of MdLACS4 in Arabidopsis induced early flowering. Compared with wild-type plants, MdLACS4 transgenic Arabidopsis exhibited lower water loss rates, reduced epidermal permeability, increased cuticular wax in stems and leaves, and altered cuticular ultrastructure. Furthermore, the accumulation of cuticular wax enhanced the resistance of MdLACS4 transgenic plants to drought and salt stress. Finally, predicted protein functional interaction networks for LACS4 suggested that the molecular regulation pathway of MdLACS4 mediates wax biosynthesis in apple
