Researchers Identify Genes that Control Tomato Fruit Shape
October 7, 2026| |
A study conducted by researchers from China has identified a genetic regulatory pathway that controls fruit shape in tomato, providing new insights into how elongated fruits develop. The study focused on the transcription factor SlBPC1 and its interaction with genes involved in fruit development.
Fruit shape is an important agricultural trait that affects consumer preference and varies widely among tomato varieties. In this study, researchers used gene editing to examine tomato plants with altered SlBPC1 activity and investigate the roles of its target genes, SlOFP2, SlOFP21, and SUN. The team also found significant findings on how SlOFP2 and SlOFP21 interact with other proteins that regulate fruit elongation.
The results showed that knocking out SlBPC1 produced more elongated fruits by changing cell division patterns during ovary development. Overexpressing either SlOFP2 or SlOFP21 also increased fruit elongation. The study identified the SlBPC1-SlOFP2/SlOFP21/SUN regulatory module as a potential target for improving fruit shape in tomato breeding.
