Abstract excerpt
Ascorbic acid (AsA) determines fruit nutritional quality and antioxidant capacity in tomato, but available genetic resources for its improvement are limited. Here, we integrated natural variation analysis with upstream open reading frames (uORFs) editing to identify and engineer determinants of AsA accumulation. A natural variant in GGP2 was significantly associated with fruit AsA content, leading to the...
