Abstract

In a recent study, Bournonville et al. identified that the tomato PAS/LOV (PLP) photoreceptor downregulates ascorbate synthesis via inhibiting the GDP-L-galactose phosphorylase (VTC2; GGP) activity. This finding describes the role of PLP as a novel regulator for dark-light regulation of ascorbate and provides insight for future research in this field.
