Summary

Story summary

Researchers at the Chinese Academy of Sciences examined the SlVI gene in tomatoes, essential for sugar metabolism and fruit quality.
Knocking out SlVI increased shelf life and resistance to Botrytis cinerea.
Overexpressing SlVI improved leaf size and chlorophyll content, linking sugar metabolism to growth.
SlVI-deficient tomatoes had 16 times more sucrose and higher flavonoid naringenin, resulting in sweeter fruit.
Postharvest analyses showed improved firmness and reduced water loss in SlVI-deficient fruit.
