Heterologous expression of LbbHLH36 from Lycium barbarum enhances carotenoid accumulation in tomato fruits via synergistic activation of biosynthesis and suppression of degradation.
Findings reveal that LbbHLH36 acts as a positive regulator of carotenoid accumulation in tomato through a dual mechanism that concurrently regulate biosynthetic flux and attenuates catabolic degradation, highlighting its value as a candidate gene for nutritional quality improvement in Lycium barbarum, tomato, and other...
