Journal ArticleDOI
Nitric Oxide Is Required for Root Organogenesis
TL;DR: It is demonstrated that nitric oxide mediates the auxin response leading the adventitious root formation and a transient increase in NO concentration was shown to be required and to be part of the molecular events involved in adventitiousRoot development induced by indole acetic acid.
Journal ArticleDOI
Formation of reactive species and induction of antioxidant defence systems in polar and temperate marine invertebrates and fish
Doris Abele,Susana Puntarulo +1 more
TL;DR: This review summarizes current knowledge on pro- and antioxidant processes in marine invertebrates and fish, and relates reactive oxygen species (ROS) formation in polar ectotherms to homeoviscous adaptations of membrane and storage lipids, as well as to tissue hypoxia and re-oxygenation during physiological stress.
Journal ArticleDOI
Temperature-dependence of mitochondrial function and production of reactive oxygen species in the intertidal mud clam Mya arenaria
TL;DR: Oxygen radical formation was directly dependent on temperature-controlled respiration rates in states 3 and 4 and inversely related to mitochondrial coupling (RCR+) in state 4 and is therefore involved in cellular heat stress in this eurythermal marine ectotherm.
Journal ArticleDOI
Iron, oxidative stress and human health.
TL;DR: Overall, further studies are required to assess more effective means to limit iron-dependent damage, by minimizing the formation and release of free radicals in tissues when the cellular iron steady state concentration is increased either as a consequence of disease or by therapeutic iron supplementation.
Journal ArticleDOI
Chloroplasts as a nitric oxide cellular source. Effect of reactive nitrogen species on chloroplastic lipids and proteins.
TL;DR: Data reported here suggest that NO is an endogenous metabolite in soybean chloroplasts and that reactive nitrogen species could exert either antioxidant or prooxidant effects on chloroplast macromolecules.
