This study reviews the research achievements made in recent years regarding the synthesis of anthocyanins in Morella rubra. Key genes such as CHS, CHI and F3H play an important role in the synthesis process of anthocyanins. In addition, some factors that regulate these genes, such as R2R3-MYB, bHLH and WD40, also play a role in the regulatory process. There is also a mutually cooperative relationship among them. To figure out how these genes work, researchers employed methods such as cloning genes, analyzing expression patterns, and also studied the epigenetic regulation of genes. This study also introduces the application prospects of molecular breeding, genetic engineering and CRISPR technology in improving the color and nutritional value of Morella rubra. It is hoped that these achievements can provide a scientific basis for improving the quality of Morella rubra and also bring practical methods for planting and breeding.
