Formation and regulatory network of fruit aroma components of Rosaceae plants

The Rosaceae family of angiosperms contains a wide variety of plants, including important economic fruits such as apples, peaches, pears, strawberries, blackberries and raspberries. These fruits are popular among consumers because of their rich nutrition, delicious and juicy pulp and pleasant aroma. In recent years, breeders have been committed to improving fruit quality, and the aroma of fruits has attracted much attention as a key factor in quality control. The formation of aroma components is the result of multigene regulation and is closely related to genetic background, environmental climate, cultivation management and postharvest treatment. Many studies on the formation of aroma components in Rosaceae fruit trees have been conducted. In this paper, the methods for detecting aroma compounds are summarized, as are the main volatile components of Rosaceae fruit trees and the key factors affecting aroma formation. In particular, this paper focuses on important research on aroma biosynthesis pathways, key genes, transcription factors and epigenetic factors related to the formation of aroma compounds, aiming to improve the understanding of fruit aroma formation and provide a reference for the breeding of Rosaceae fruit trees.
