Summary Plant‐derived Vitamin C (l‐ascorbic acid (AsA)) is crucial for human health and wellbeing and thus increasing AsA content is of interest to plant breeders. In plants GDP‐l‐galactose phosphorylase (GGP) is a key biosynthetic control step and here evidence is presented for two new transcriptio...
