Redox Homeostasis via Gene Families of Ascorbate-Glutathione Pathway

Frontiers in Environmental Science, 2015
The imposition of environmental stresses on plants brings about disturbance in their metabolism thereby negatively affecting their growth and development and leading to reduction in the productivity. One of the manifestations of abiotic and biotic stress

Changes in element accumulation, phenolic metabolism, and antioxidative enzyme activities in the red-skin roots of Panax ginseng

Journal of Ginseng Research, 2017
Background: Red-skin root disease has seriously decreased the quality and production of Panax ginseng (ginseng). Methods: To explore the disease's origin, comparative analysis was performed in different parts of the plant, particularly the epidermis ...

Crosstalk between brassinosteroid signaling, ROS signaling and phenylpropanoid pathway during abiotic stress in plants: Does it exist?

Plant Stress, 2022
Numerous studies have highlighted the BR (brassinosteroid) induced stress tolerance to different environmental cues. Increased free radicals and other oxidative species are produced in plant system by various environmental stresses such as high, low ...

Changes in the ascorbate-glutathione system during storage of recalcitrant seeds of Acer saccharinum L.

Acta Societatis Botanicorum Poloniae, 2011
Two seed lots of Acer saccharinum (recalcitrant), with an initial moisture content of 50% and 55%, were stored at +3oC for 6 months. After this time, their viability (measured as germinability) reached 100% and 30%, respectively.

Over-Expression of Dehydroascorbate Reductase Improves Salt Tolerance, Environmental Adaptability and Productivity in Oryza sativa

Antioxidants, 2022
Abiotic stress induces reactive oxygen species (ROS) generation in plants, and high ROS levels can cause partial or severe oxidative damage to cellular components that regulate the redox status.

Novel insight into functions of ascorbate peroxidase in higher plants: More than a simple antioxidant enzyme

Redox Biology, 2023
As plants are sessile organisms, they are inevitably exposed to a variety of environmental stimuli that trigger rapid changes in the generation and disposal of reactive oxygen species such as hydrogen peroxide (H2O2).

Ascorbate-Glutathione Cycle Genes Families in Euphorbiaceae: Characterization and Evolutionary Analysis

Biology, 2022
Ascorbate peroxidase (APX), Monodehydroascorbate Reductase (MDAR), Dehydroascorbate Reductase (DHAR) and Glutathione Reductase (GR) enzymes participate in the ascorbate-glutathione cycle, which exerts a central role in the antioxidant metabolism in ...

The Antioxidants of Legume Nodule Mitochondria

Molecular Plant-Microbe Interactions, 2001
The mitochondria of legume root nodules are critical to sustain the energy-intensive process of nitrogen fixation. They also generate reactive oxygen species at high rates and thus require the protection of antioxidant enzymes and metabolites.

Melatonin: Awakening the Defense Mechanisms during Plant Oxidative Stress

Plants, 2020
Melatonin is a multifunctional signaling molecule that is ubiquitously distributed in different parts of a plant and responsible for stimulating several physio-chemical responses to adverse environmental conditions. In this review, we show that, although
