TL;DR: The production of superoxide radical (O 2 .- ) was studied in plasma membrane vesicles isolated by aqueous polymer two-phase partitioning from roots of zinc-sufficient and zinc-deficient bean (Phaseolus vulgaris L. cv. Prelude) plants.

Abstract: The production of superoxide radical (O 2 .- ) was studied in plasma membrane vesicles isolated by aqueous polymer two-phase partitioning from roots of zinc-sufficient and zinc-deficient bean (Phaseolus vulgaris L. cv. Prelude) plants. The two populations of vesicles were highly enriched in plasma membrane and had similar composition as evidenced by the specific membrane marker enzymes. Vesicles from zinc-deficient roots showed higher rates of NAD(P)H oxidation compared to vesicles from zinc-sufficient plants. The NAD(P)H-dependent formation of O 2 .- in plasma membrane vesicles was also highly increased by zinc deficiency

Tansley Review No. 111: Possible roles of zinc in protecting plant cells from damage by reactive oxygen species.
TL;DR: Zinc plays critical roles in the defence system of cells against ROS, and thus represents an excellent protective agent against the oxidation of several vital cell components such as membrane lipids and proteins, chlorophyll, SH-containing enzymes and DNA.

TL;DR: The Cd-induced production of the ROS, H2O2 and O2·−, could be attributed to the phytotoxic effect of Cd, but lower levels of ROS could function as signal molecules in the induction of defence genes against Cd toxicity.

Involvement of plasma-membrane NADPH oxidase in abscisic acid- and water stress-induced antioxidant defense in leaves of maize seedlings.
Mingyi Jiang,Jianhua Zhang +1 more
TL;DR: Data indicate that NADPH oxidase is involved in the ABA-induced production of active oxygen species (AOS), and results depict a minimal chain of events initiated by water stress-induced ABA accumulation, which then triggers the production of AOS by membrane-bound NAD PH oxidase, resulting in the induction of antioxidant defense systems against oxidative damage in plants.

Involvement of polyamines in the chilling tolerance of cucumber cultivars.
TL;DR: The results suggest that Spd plays important roles in chilling tolerance of cucumber, probably through prevention of chill-induced activation of NADPH oxidases in microsomes and alleviated chilling injury.
