Tomato Oxalyl-CoA Synthetase Degrades Oxalate and Affects Fruit Quality

open access: yesFrontiers in Plant Science, 2022
Acyl activating enzyme 3 (AAE3) encodes oxalyl-CoA synthetase involved in oxalate degradation. In this study, we investigated the role of AAE3 (SlAAE3) in the fruit quality of tomato (Solanum lycopersicum).
