Nitric oxide (NO) is a bioactive molecule that exerts a number of diverse activities in
phylogenetically distant species, as well as opposing effects in related biological systems. It …

Plant peroxisomes are highly dynamic organelles with regard to metabolic pathways,
number and morphology and participate in different metabolic processes and cell responses …

Abstract Calcium ion (Ca 2+) is a versatile signaling transducer in all eukaryotic organisms.
In plants, intracellular changes in free Ca 2+ levels act as regulators in many growth and …

Peroxisomes are the cellular location of many antioxidants and are themselves significant
producers of reactive oxygen species. In this report we demonstrate the induction of …

Calluses from two ecotypes of reed (Phragmites communis Trin.) plant (dune reed [DR] and
swamp reed [SR]), which show different sensitivity to heat stress, were used to study plant …

The ascorbate–glutathione cycle is a metabolic pathway that detoxifies hydrogen peroxide
and involves enzymatic and non-enzymatic antioxidants. Proteomic studies have shown that …

Nitric oxide (NO) controls diverse functions in many cells and organs of animals. It is also
produced in plants and has a variety of effects, but little is known about their underlying …

Nitric oxide (NO), a signaling free radical, is directly or indirectly involved in virtually all plant
physiological processes. Although the enzymatic NO source L-arginine (L-Arg)-dependent …

Plants are sessile organisms therefore, cannot avoid adverse environmental conditions
(such as soil salinity, drought, heat, cold, flooding and heavy metal contamination). These …

Nitric oxide (NO) is a double-edged sword–it can be either beneficial and activate defence
responses in plants and animals or, together with reactive oxygen species, it can kill not only …
