Abstract:Cuticle is a hydrophobic layer mainly composed of cutin and wax formed on the surface of aerial organs in order to adapt to the terrestrial environment during the evolution of aquatic plants to terrestrial plants. Fruit cuticle plays an important role in resisting abiotic and biotic stress and maintaining the storage quality of fruits after harvest. At present, the research on fruit cuticle is still in its infancy. This paper reviewed the composition, function, biosynthesis, regulation and research methods of fruit cuticle based on relevant research progress in recent years, and put forward the prospect of future research direction.
