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 …

Oxygen is a natural acceptor of electrons in the respiratory pathway of aerobic organisms
and in many other biochemical reactions. Aerobic metabolism is always associated with the …

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 …

Light intensity and temperature are primary environmental factors affecting the growth and
development of plants. Changes in their intensity, range and duration can lead to …

Various abiotic stresses lead to the overproduction of reactive oxygen species (ROS) in
plants which are highly reactive and toxic and cause damage to proteins, lipids …

Reactive oxygen species (ROS) are produced in plants as byproducts during many
metabolic reactions, such as photosynthesis and respiration. Oxidative stress occurs when …

Reactive oxygen species (ROS) are a by-product of normal cell metabolism in plants;
however, under stress conditions, the balance between production and elimination is …

With the advent of human civilization and anthropogenic activities in the shade of
urbanization and global climate change, plants are exposed to a complex set of abiotic …

Reactive oxygen species (ROS) play a dual role in plant biology acting on the one hand as
important signal transduction molecules and on the other as toxic by‐products of aerobic …

Organisms have evolved endogenous biological clocks as internal timekeepers to
coordinate metabolic processes with the external environment. Here, we seek to understand …
