metabolism | D-galacturonate reductase (GalUR) is a key enzyme involved in D-galacturonate pathway of AsA biosynthesis. L-Ascorbic acid (AsA) biosynthesis through the L-galactose pathway supplemented by D-galacturonic acid pathway and AsA recycling collectively contributes to accumulating and remaining higher AsA level in kiwifruit cv. White during postharvest. L-Galactose dehydrogenase (GalDH) activity and relative expressions of the genes encoding GDP-D-mannose diphosphorylase (GMP), L-galactose-1-P phosphatase (GPP), GDP-L-galactose phosphorylase (GGP), GalDH and GalUR are important for regulation of AsA biosynthesis. The activity and expression of dehydroascorbate reductase (DHAR) are primarily responsible for regulation of AsA recycling in kiwifruit cv. White during postharvest. Changes in activities of enzymes involved in AsA metabolism in the fruit during storage, quantitative real-time PCR expression analysis. A minor change is observed in GalUR activity. The relative expression of GalUR increases sharply to a peak at day 13, and then decreases gradually and continuously | Actinidia eriantha |
