Research progress on utilization and molecular biology of blackberry

Blackberry (Rubus spp.) is a berry fruit of the Rosaceae family, which has the advantages of strong ecological adaptability, easy cultivation, early yield and good economic benefits. The fresh fruits are soft and juicy, and mature fruits are predominantly deep purple-black, rich in pigments, and have mellow and delicious flavor. Relying on the abundant nutritional contents and functional substances such as polyphenols, flavonoids and anthocyanins, they have received widespread attention and popularity in Europe, the United States and other regions. Therefore, this article aims to summarize the origin and development of blackberry, as well as relevant advances in its nutritional composition, medicinal value, processing and utilization. In addition, research progress on the molecular biology of blackberry is covered. This article also provides in-depth insights and prospects on problems arising from blackberry research and utilization as well as future development trends, so as to provide an effective reference for the sustainable development and utilization of the blackberry industry.
