The expression of BrMDHAR gene in chloroplasts and mitochondria enhances tolerance to freezing stress in Arabidopsis thaliana

Biologia Plantarum, 2014
In chloroplasts and mitochondria, antioxidant mechanisms include the ascorbate-glutathione cycle, and monodehydroascorbate reductase (MDHAR) is important for regeneration of ascorbate (AsA) from monodehydroascorbate (MDHA).

Key metabolites secreted by Chlorella vulgaris alleviate salt stress in soybean seedlings

Journal of Integrative Plant Biology, EarlyView.
Chlorella vulgaris secretes exosome‐derived linolenic acid and inosine, which alleviate salt stress and enhance salt tolerance in soybean seedlings by activating stress‐responsive signaling networks. ABSTRACT Soil salinization is a major abiotic stress factor that reduces soybean production.

High resolution imaging of temporal and spatial changes of subcellular ascorbate, glutathione and H₂O₂ distribution during Botrytis cinerea infection in Arabidopsis.

PLoS ONE, 2013
In order to study the mechanisms behind the infection process of the necrotrophic fungus Botrytis cinerea, the subcellular distribution of hydrogen peroxide (H₂O₂) was monitored over a time frame of 96 h post inoculation (hpi) in Arabidopsis thaliana Col-

OsCPN10a, cooperating with OsCPN20 and OsHSP60‐3B negatively regulate ABA signaling and enhance seed storability in rice

Journal of Integrative Plant Biology, EarlyView.
Abscisic acid signaling homeostasis is essential for seed storability. The molecular chaperone OsCPN10a enhances rice seed storability by forming a trimeric chaperone complex with OsCPN20‐OsHSP60‐3B that attenuates abscisic acid signaling via direct interaction with OsPYL10‐OsABIL1, thereby maintaining starch integrity and offering a promising target ...

The Role of Oxidative Stress in Periodontitis

Journal of Periodontal Research, EarlyView.
Oxidative stress is involved in multiple chemical reactions that take place in different intracellular organelles: mitochondria, rough endoplasmic reticulum, peroxisomes, autophagy, and aging, and can be influenced by exogenous factors: nutrition, physical activity, psychological status, environmental conditions, microbiome, and drugs.

Oligo-Carrageenan Kappa-Induced Reducing Redox Status and Activation of TRR/TRX System Increase the Level of Indole-3-acetic Acid, Gibberellin A3 and trans-Zeatin in Eucalyptus globulus Trees

Molecules, 2014
Eucalyptus globulus trees treated with oligo-carrageenan (OC) kappa showed an increase in NADPH, ascorbate and glutathione levels and activation of the thioredoxin reductase (TRR)/thioredoxin (TRX) system which enhance photosynthesis, basal metabolism ...

An atlas of plant selenium metabolism

New Phytologist, EarlyView.
Summary Selenium (Se) is not only a rare and toxic element but also an essential micronutrient for humans and animals that is often in short supply. Terrestrial plants do not require Se, but it can have growth‐promoting or negative effects, depending on the exposure level.

Effector‐Mediated Spatial Reprogramming of Glycolate Oxidase Subverts Peroxisomal and Membrane‐Associated ROS Defences

Plant Biotechnology Journal, EarlyView.
ABSTRACT Oomycete pathogens secrete hundreds of RXLR effectors into plant cells to modulate host immunity by targeting diverse plant proteins. Here, we report that the Peronophythora litchii RXLR effector PlAvh133 acts as a virulence factor and targets the litchi glycolate oxidase (GLO) LcGLO1, a key enzyme in photorespiration, thereby suppressing ...

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 ...

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.).
