Huang W.Z., 2025, Key genes regulating fruit size and sugar content in grapevine, Tree Genetics and Molecular Breeding, 15(2): 62-69 (doi: 10.5376/tgmb.2025.15.0008)

This study explains the key genes that affect the size and sugar content of grape fruits and their regulatory patterns, and analyzes genes such as VvGH9, VvSK1, and VvHB58, which are crucial in the process of fruit enlargement and sugar increase and play an important role in fruit development and sugar accumulation. This study also mentioned the influences of epigenetics, small RNAs and environmental conditions on grape traits, as well as the application of new gene editing technologies in grape breeding. This study aims to provide new ideas and genetic targets for improving the quality of grapevines and propose useful strategies for future breeding work.
