Salt tolerance of transgenic rice overexpressing yeast mitochondrial Mn-SOD in chloroplasts
TLDR
It is suggested that increased levels of ascorbate peroxidase and high levels of chloroplastic SOD in the transformant are important factors for salt resistance in rice.About:

Physiology and molecular biology of salinity stress tolerance in plants
Raj Kumar Sairam,Aruna Tyagi +1 more
TL;DR: Salinity stress response is multigenic, as a number of processes affected, such as various compatible solutes/osmolytes, polyamines, reactive oxygen species and antioxidant defence mecha- nism, ion transport and compartmentalization of inj u- rious ions.
Journal ArticleDOI
Biotechnological approach of improving plant salt tolerance using antioxidants as markers.
TL;DR: The role of different antioxidants as potential selection criteria for improving plant salt tolerance has been critically discussed and the potential of this approach in counteracting stress-induced oxidative stress has been discussed at length in this review.
Journal ArticleDOI
Galactinol and raffinose constitute a novel function to protect plants from oxidative damage.
TL;DR: The possibility that galactinol and raffinose scavenge hydroxyl radicals as a novel function to protect plant cells from oxidative damage caused by MV treatment, salinity, or chilling is suggested.
Journal ArticleDOI
Antioxidant systems and o2.?/h2o2 production in the apoplast of pea leaves. its relation with salt-induced necrotic lesions in minor veins
TL;DR: The results suggest a strong interaction between both cell compartments in the control of the apoplastic ASC content in pea leaves, but this anti-oxidative response does not seem to be sufficient to remove the harmful effects of high salinity.
Journal ArticleDOI
ROS homeostasis in halophytes in the context of salinity stress tolerance
TL;DR: It is argued that truly salt-tolerant species possessing efficient mechanisms for Na(+) exclusion from the cytosol may not require a high level of antioxidant activity, as they simply do not allow excessive ROS production in the first instance.

TL;DR: Fluorescence as a Reaction Competing in the Deactivation of Excited Chlorophyll and the Origin of Fluorescence Emission.

H2O2 from the oxidative burst orchestrates the plant hypersensitive disease resistance response
TL;DR: It is reported here that H2O2 from this oxidative burst not only drives the cross-linking of cell wall structural proteins, but also functions as a local trigger of programmed death in challenged cells and as a diffusible signal for the induction in adjacent cells of genes encoding cellular protectants.
Journal ArticleDOI
Superoxide dismutase and stress tolerance
TL;DR: Prospects for Stress Tolerance through Genetic Engineering of SOD and MnSOD Overexpression are surveyed, and the Mechanism of Sod Regulation is studied.

Protection against oxygen radicals: an important defence mechanism studied in transgenic plants
TL;DR: 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.

Antioxidant response to NaCl stress in salt-tolerant and salt-sensitive cultivars of cotton
TL;DR: Protection from oxidative damage by higher levels of antioxidants and a more active ascorbate-glutathione cycle may be involved in tbe development of salt tolerance in cotton.
