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 …

Throughout evolution, a number of animals including humans have lost the ability to
synthesize ascorbic acid (ascorbate, vitamin C), an essential molecule in the physiology of …

Abstract Hydrogen peroxide (H2O2) is an important signal molecule involved in plant
development and environmental responses. Changes in H2O2 availability can result from …

Oxidative stress resulting from increased availability of reactive oxygen species (ROS) is a
key component of many responses of plants to challenging environmental conditions. The …

Production of reactive oxygen species (ROS), which are a by-product of normal cell
metabolism in living organisms, is an inevitable consequence of aerobic life on Earth, and …

Abstract l-Ascorbic acid (vitamin C) in fruits and vegetables is an essential component of
human nutrition. Surprisingly, only limited information is available about the pathway (s) …

l‐Ascorbic acid (vitamin C) is as essential to plants as it is to animals. Ascorbic acid functions
as a major redox buffer and as a cofactor for enzymes involved in regulating photosynthesis …

Ascorbic acid is a well‐known antioxidant and cellular reductant with an intimate and
complex role in the response of plants to ozone. It is clear from a number of studies that …

Plants synthesize ascorbate from guanosine diphosphate (GDP)‐mannose via l‐galactose/l‐
gulose, although uronic acids have also been proposed as precursors. Genes encoding all …

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 …
