Salinity is a growing problem affecting soils and agriculture in many parts of the world. The
presence of salt in plant cells disrupts many basic metabolic processes, contributing to …

Abstract Reduction-oxidation (redox) reactions, in which electrons move from a donor to an
acceptor, are the functional heart of photosynthesis. It is not surprising therefore that reactive …

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 …

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 …

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 …

Soil salinity is a major threat to agricultural sustainability and a global food security. Until
now, most research has concentrated around stomatal limitation to photosynthesis, while …

Reactive oxygen species (ROS) have a profound influence on almost every aspect of plant
biology. Here, we emphasize the fundamental, intimate relationships between light‐driven …

Recent years have witnessed enormous progress in understanding redox signaling related
to reactive oxygen species (ROS) in plants. The consensus view is that such signaling is …

Silicon (Si) is the most abundant mineral element in the earth's crust. Some plants actively
accumulate Si as amorphous silica (phytoliths), which can protect plants from stresses. Here …

Plants are confronted with a variety of environmenmtal stresses resulting in enhanced
production of ROS. Plants require a threshold level of ROS for vital functions and any …
