The recent findings on responses, adaptation, and tolerance to HT at the cellular, organellar, and whole plant levels are reviewed and various approaches being taken to enhance thermotolerance in plants are described.
Molecular Mechanism of Heavy Metal Toxicity and Tolerance in Plants: Central Role of Glutathione in Detoxification of Reactive Oxygen Species and Methylglyoxal and in Heavy Metal Chelation
The aim of this review is to integrate a recent understanding of physiological and biochemical mechanisms of HM-induced plant stress response and tolerance based on the findings of current plant molecular biology research.
Reactive Oxygen Species and Antioxidant Defense in Plants under Abiotic Stress: Revisiting the Crucial Role of a Universal Defense Regulator
This review has documented the recent advancement illustrating the harmful effects of ROS, antioxidant defense system involved in ROS detoxification under different abiotic stresses, and molecular cross-talk with other important signal molecules such as reactive nitrogen, sulfur, and carbonyl species.

It is suggested that both betaine and proline provide a protective action against Cd-induced oxidative stress by reducing H2O2 and lipid peroxidation levels and by increasing the antioxidant defense and MG detoxification systems.
Exogenous sodium nitroprusside alleviates arsenic-induced oxidative stress in wheat (Triticum aestivum L.) seedlings by enhancing antioxidant defense and glyoxalase system
The results suggest that the exogenous application of NO rendered the plants more tolerant to As-induced oxidative damage by enhancing their antioxidant defense and glyoxalase system.
Plant Response to Salt Stress and Role of Exogenous Protectants to Mitigate Salt-Induced Damages
This chapter attempts to summarize differential responses of plants to salinity with special reference to growth, physiology and yield and discusses the progress made in using exogenous protectants to mitigate salt-induced damages in plants.

Investigation of the regulatory role of exogenous selenium in the antioxidant defense and methylglyoxal (MG) detoxification systems in rapeseed seedlings exposed to salt stress suggests that the exogenous application of Se rendered the plants more tolerant to salt Stress-induced oxidative damage by enhancing their antioxidants defense and MG detoxification system.
Hydrogen peroxide priming modulates abiotic oxidative stress tolerance: insights from ROS detoxification and scavenging
Current knowledge of the possible mechanisms associated with H2O2-induced abiotic oxidative stress tolerance in plants is reviewed, with special reference to antioxidant metabolism.
Potassium: A Vital Regulator of Plant Responses and Tolerance to Abiotic Stresses
In this review, the recent literature on the biological functions of K, its uptake, its translocation, and its role in plant abiotic stress tolerance are summarized.
Nitric oxide modulates antioxidant defense and the methylglyoxal detoxification system and reduces salinity-induced damage of wheat seedlings
The results suggest that the exogenous application of NO rendered the plants more tolerant to salinity-induced oxidative damage by enhancing their antioxidant defense and MG detoxification systems.
