Exogenous Glutathione Increases Arsenic Translocation Into Shoots and Alleviates Arsenic-Induced Oxidative Stress by Sustaining Ascorbate–Glutathione Homeostasis in Rice Seedlings

Frontiers in Plant Science, 2019
Glutathione (GSH) plays diverse roles in the physiological processes, stress defense, growth, and development of plants. This study investigated the effects of exogenous GSH on the biochemical responses of reactive oxygen species and antioxidant levels ...

OsFeSOD3 Functions as an Enzymatic Component of the PEP Complex, Bifunctionally Regulating Chloroplastic ROS Metabolism and Chloroplast Biogenesis in Rice

Plant Biotechnology Journal, EarlyView.
ABSTRACT Chloroplasts are essential organelles responsible for photosynthesis, providing energy and metabolic intermediates required for plant growth and productivity. Chloroplast development is highly sensitive to environmental stresses such as drought, and this sensitivity is closely associated with growth inhibition and yield reduction under stress ...

Stress-triggered redox signalling: What’s in pROSpect? [PDF]

, 2016
Reactive oxygen species (ROS) have a profound influence on almost every aspect of plant biology. Here, we emphasize the fundamental, intimate relationships between light-driven reductant formation, ROS, and oxidative stress, together with compartment ...

3‐Methyl‐1‐Butanol Enhances Postharvest Resistance of Red Grapes to Botrytis cinerea by Activating Phenylpropanoid Metabolism and Antioxidant Defences

Plant Biotechnology Journal, EarlyView.
ABSTRACT Grey mould, caused by Botrytis cinerea, is a significant postharvest disease leading to substantial economic losses in the grape industry. This study investigated the regulatory mechanism of 3‐methyl‐1‐butanol (3M1B), a yeast volatile substance, on B. cinerea resistance in red grapes (Vitis vinifera L.).

Linking Superoxide Production and Scavenging in Plant Development

Plant, Cell &Environment, EarlyView.
ABSTRACT Due to their strong oxidizing potential, rapid membrane permeability, and high reactivity, reactive oxygen species (ROS) play essential roles in plant development and stress responses. Superoxide (O2•‐) is a primary product of molecular oxygen reduction and a crucial source of hydrogen peroxide, representing a ROS species of substantial ...

Reactive oxygen species in Hevea brasiliensis latex and relevance to tapping panel dryness [PDF]

, 2016
Environmental stress can lead to oxidative stress resulting from an increase in reactive oxygen species (ROS) and involves redox adjustments. Natural rubber is synthesized in laticifers, which is a non-photosynthetic tissue particularly prone to ...

Role of reactive oxygen species in mediating peripheral hypoxic vasodilation and sympathoexcitation at high altitude

The Journal of Physiology, EarlyView.
Abstract figure legend High‐altitude acclimatisation increases muscle sympathetic nerve activity (MSNA) via activation of the arterial chemoreflex, pulmonary arterial baroreceptors and resetting of the sympathetic vascular baroreflex. However attempting to silence these mechanisms only partially normalises MSNA, implicating other contributory ...

Hydrogen sulfide enhances salt tolerance in sorghum by activating the chloroplastic AsA–GSH cycle to sustain photosynthesis

Frontiers in Plant Science
Soil salinization poses a severe threat to global food security by reducing crop productivity, particularly in semi-arid regions where sorghum (Sorghum bicolor L.) is a major cereal crop. Hydrogen sulfide (H₂S) has recently been recognized as a signaling
