Plants suffering from abiotic stress are commonly facing an enhanced accumulation of
reactive oxygen species (ROS) with damaging as well as signalling effects at organellar and …

Sugars play important roles as both nutrients and regulatory molecules throughout plant life.
Sugar metabolism and signalling function in an intricate network with numerous hormones …

Recent in vitro, in vivo, and theoretical experiments strongly suggest that sugar-(like)
molecules counteract oxidative stress by acting as genuine reactive oxygen species (ROS) …

Ascorbate (vitamin C) is an essential antioxidant in fresh fruits and vegetables. To gain
insight into the regulation of ascorbate metabolism in plants, we studied mutant tomato …

Ascorbic acid (AsA) is an important antioxidant in plants, and its biosynthesis is finely
regulated through developmental and environmental cues; however, the regulatory …

Nucleotide sugars are the universal sugar donors for the formation of polysaccharides,
glycoproteins, proteoglycans, glycolipids, and glycosylated secondary metabolites. At least …

Ascorbate, or vitamin C, is obtained by humans mostly from plant sources. Various
approaches have been made to increase ascorbate in plants by transgenic means. Most of …

In the past year, the last missing enzyme of the l-galactose pathway, the linear form of which
appears to represent the major biosynthetic route to l-ascorbate (vitamin C) in higher plants …

It is widely accepted that the predominant ascorbate biosynthesis pathway in green plants is
via GDP-mannose and l-galactose. d-galacturonic, d-glucuronic acid and GDP-l-gulose …

Abiotic stresses, such as drought, salinity, and extreme temperatures, are major limiting
factors in global crop productivity and are predicted to be exacerbated by climate change …
