Ascorbic acid (AsA) participates in diverse biological processes, is regulated by multiple factors and is a potent antioxidant and cellular reductant. The D-Mannose/L-Galactose pathway is a major plant AsA biosynthetic pathway that is highly connected within biosynthetic networks, and generally

We initially observed that Brassica rapa cultivars containing the Turnip mosaic virus (TuMV) resistance gene, Rnt1-1, accumulated a high level of endogenous ascorbic acid (AS) and dehydroascobic acid (DHA) when infected with TuMV. We here hypothesized a possible contribution of an elevated level of

Ascorbic acid (L-AsA) is an important antioxidant in plants and humans. Vegetables are one of the main sources of ascorbic acid for humans. For instance, non-heading Chinese cabbage (Brassica campestris ssp. chinensis Makino) is considered as one of the most important vegetables in south China. To

Phosphomannose isomerase (PMI) is an enzyme that catalyses the first step of the L-galactose pathway for ascorbic acid (AsA) biosynthesis in plants. To clarify the physiological roles of PMI in AsA biosynthesis, the cDNA sequence of PMI was cloned from non-heading Chinese cabbage (Brassica

Ascorbic acid (AsA) is an important antioxidant in plants and an essential vitamin for humans. Extending the study of AsA-related genes from Arabidopsis thaliana to Brassica rapa could shed light on the evolution of AsA in plants and inform crop breeding. In this study, we conducted whole-genome
