Reactive oxygen species (ROS) are produced as a normal product of plant cellular
metabolism. Various environmental stresses lead to excessive production of ROS causing�…

Cereals and legumes are outstanding sources of macronutrients, micronutrients,
phytochemicals, as well as antinutritional factors. These components present a complex�…

Oxidative stress is induced by a wide range of environmental factors including UV stress,
pathogen invasion (hypersensitive reaction), herbicide action and oxygen shortage. Oxygen�…

▪ Abstract Photoreduction of dioxygen in photosystem I (PSI) of chloroplasts generates
superoxide radicals as the primary product. In intact chloroplasts, the superoxide and the�…

The discovery that there is a close relationship between ascorbate and glutathione dates
from soon after the characterization of the chemical formulae of the two molecules (Szent�…

Over-production of reactive oxygen species (ROS) in plants under stress conditions is a
common phenomenon. Plants tend to counter this problem through their ability to synthesize�…

Pectin is a family of complex polysaccharides present in all plant primary cell walls. The
complicated structure of the pectic polysaccharides, and the retention by plants of the large�…

▪ Abstract The involvement of excited and highly reactive intermediates in oxygenic
photosynthesis poses unique problems for algae and plants in terms of potential oxidative�…

▪ Abstract The production of reactive oxygen species (ROS), such as O2− and H2O2, is an
unavoidable consequence of aerobic metabolism. In plant cells the mitochondrial electron�…

Humans are unable to synthesise l‐ascorbic acid (L‐AA, ascorbate, vitamin C), and are thus
entirely dependent upon dietary sources to meet needs. In both plant and animal�…
