Ascorbic acid is synthesised by eukaryotes, the known exceptions being primates and some
other animal groups which have lost functional gulonolactone oxidase. Prokaryotes do not …

Vitamin C (l-ascorbic acid) is an excellent free radical scavenger, not only for its capability to
donate reducing equivalents but also for the relative stability of the derived …

Significance: The concept that vitamin C (l-ascorbic acid) is at the heart of the peroxide
processing and redox signaling hub in plants is well established, but our knowledge of the …

Ascorbate (vitamin C) is an essential antioxidant and enzyme cofactor in both plants and
animals. Ascorbate concentration is tightly regulated in plants, partly to respond to stress …

Highlights•Ascorbate is an essential reductant/antioxidant in plants.•The concentration of
ascorbate varies between plant tissues and different plants.•GDP-galactose phosphorylase …

The enzymes involved in l-ascorbate biosynthesis in photosynthetic organisms (the Smirnoff–
Wheeler [SW] pathway) are well established. Here, we analyzed their subcellular …

Ascorbate is a major antioxidant buffer in plants. Several approaches have been used to
increase the ascorbate content of fruits and vegetables. Here, we combined forward …

Highlights•Developing crops with higher ascorbate levels is needed to enhance human
nutrition.•Dietary ascorbate (vitamin C) influences epigenetics and enhances iron …

Varying light conditions elicit metabolic responses as part of acclimation with changes in
ascorbate levels being an important component. Here, we adopted a genome-wide …

High light stress is an important factor limiting crop yield. Light receptors play an important
role in the response to high light stress, but their mechanisms are still poorly understood …
