Superoxide dismutase (SOD) isozymes are compartmentalized in higher plants and play a major role in combating oxygen radical mediated toxicity. In this review we evaluate the mode of action and effects of the SOD isoforms with respect to oxidative stress resistance, correlating age, species, and specificity of plants during development. 
Molecular and biochemical characterization of superoxide dismutase (SOD) in upland rice under drought
TLDR
The different patterns of SOD activity and/or gene expression in upland rice plants should be strongly considered to elucidate the cellular mechanisms of drought tolerance; these findings may ultimately inform breeding programs aimed at more efficiently developing cultivars that are better adapted to areas prone to water deficits.
Oxidative Stress in Plants and Its Management
TLDR
There is a growing need to develop crops which can be resistant to the effects of various oxidative stresses, one such way is to develop transgenic plants overexpressing one or more antioxidants, which can confer resistance towards particular stress.
Effect of PEG Induced Osmotic Stress on Peroxidase and Superoxide Dismutase Isozymes in Sorghum Seedlings
The present investigation was undertaken to understand the effect of PEG-6000– induced osmotic stress on isozymes of superoxide dismutase and peroxidase as well as their activities in four each of

The aim of this study was to associate the generation of reactive oxygen species (ROS) with induced antioxidant responses and disturbed cellular redox environment in the nitrogen-(N), phosphorus-(P),
Study of the superoxide dismutase isozymes activities in different iron nutrition conditions in Aloe vera
TLDR
It could be suggested that pulp as the most important industrial usable tissue was not a source for accumulation of iron, as the activity of SOD could be induced in pulp by increasing iron concentration.

Differential regulation of superoxide dismutases in plants exposed to environmental stress.
TLDR
Evidence is presented that iron SOD mRNA abundance increases whenever there is a chloroplast- localized oxidative stress, similar to the previous finding that manganese SOD responds to mitochondria-localized events.
Manganese superoxide dismutase can reduce cellular damage mediated by oxygen radicals in transgenic plants.
TLDR
It was found that high level overproduction of MnSOD in the corresponding subcellular location could significantly reduce the amount of cellular damage which would normally occur and a generally applicable model correlating the consequences of SOD with the magnitude of its expression is presented.
Redox-activated expression of the cytosolic copper/zinc superoxide dismutase gene in Nicotiana.
TLDR
Surprisingly, the expression of the Cu/ZnSODcyt gene is induced by sulfhydryl antioxidants such as reduced glutathione, cysteine, and dithiothreitol, whereas the oxidized forms of glutATHione and cysteined have no effect.
Antioxidants in Higher Plants
TLDR
The chemistry and protective potential of sulfhydryl and hydroxyl compounds are emphasized and how tools of molecular biology may further clarify antioxidant function and response to stress are discussed.

TLDR
Two varieties of tobacco were used to generate transgenic lines overexpressing Mn-superoxide dismutase in the chloroplasts and the results suggest that in var SR1 the overexpressed MnSOD enhances primarily the stromal antioxidant system.

TLDR
Transgenic plants offered a means by which to achieve a more complete understanding of the roles of the enzymes involved in protection against stress of many types: environmental and man-made.

TLDR
Developmentally controlled mechanisms determining basal antioxidant enzyme activities, and not inductive responses, appear to be critical factors mediating short-term oxidative stress resistance.

The light-dependent generation of active oxygen species is termed photooxidative stress. This can occur in two ways: (1) the donation of energy or electrons directly to oxygen as a result of

TLDR
It is postulated that SODCc expression is directly linked to a cell-specific production of excess superoxide radicals in the cytosol.
