Arabidopsis thaliana plants with null mutations in the genes encoding the α and β subunits
of the single heterotrimeric G protein are less and more sensitive, respectively, to O3 …

The Arabidopsis thaliana protein nitric oxide synthase1 (NOS1) is needed for nitric oxide
(NO) synthesis and signaling during defense responses, hormonal signaling, and flowering …

In plants, hydrogen peroxide (H2O2) plays a major signaling role in triggering both a
defense response and cell death. Increased cellular H2O2 levels and subsequent redox …

Reactive oxygen species (ROS) are involved in the oxidative damage of the cyanobacterium
Anabaena sp. caused by UV-B (280–315 nm) radiation. UV-B-induced overproduction of …

The accumulation of hydrogen peroxide (H2O2) in plants is typically associated with biotic or
abiotic stresses. However, H2O2 is continuously produced in cells during normal …

Research on NO in plants has gained considerable attention in recent years mainly due to
its function in plant growth and development and as a key signalling molecule in different …

The role of nitrate reduction to produce nitric oxide (NO) and its subsequent oxidation by
oxyhaemoglobin as a mechanism to maintain plant cell energetics during hypoxia is …

The plant genome is a highly redundant and dynamic genome. Here, we show that double
antisense plants lacking the two major hydrogen peroxide‐detoxifying enzymes, ascorbate …

Ozone exposure stimulates an oxidative burst in leaves of sensitive plants, resulting in the
generation and accumulation of hydrogen peroxide (H2O2) in tobacco and tomato, and …

The effects of the heavy metal Cadmium (Cd) on the growth and the activities of the
antioxidant enzymes, catalase (CAT, EC 1.11. 1.6), superoxide dismutase (SOD, EC 1.15 …
