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

open access: yesJournal 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 ...

Fascinating single‐cell red algae: models for evolution and adaptation

open access: yesNew Phytologist, EarlyView.
Summary The unicellular red algae, Cyanidiophyceae, that diverged early during Archaeplastida (algal and plant) evolution, occupy a variety of extreme habitats that are inhospitable for most other eukaryotes. With the use of modern genomics and genetics methods, Cyanidiophyceae show a remarkable taxonomic diversity, share haplodiplophasic life cycles ...

An atlas of plant selenium metabolism

open access: yesNew 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

open access: yesPlant 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

open access: yesPlant 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 ...

Reactive Oxygen Species (ROS) and Antioxidant Systems in Enhancing Plant Resilience Against Abiotic Stress

open access: yesInternational Journal of Agronomy
Reactive oxygen species (ROS) are central to plant responses under abiotic stress, acting as both damaging agents and signaling molecules. This study explores the balance between ROS production, oxidative damage, and the antioxidant defense mechanisms in

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

open access: yesPlant 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.).

Study on a Mechanism of Improving MaAPX1 Protein Activity by Mutating Methionine to Lysine

open access: yesAntioxidants
Ascorbate peroxidases (APXs) are key components of the ascorbate–glytathione cycle, which plays an important role in removing excess reactive oxygen species (ROS) in plants.

Poplar miR1447 Is a Negative Regulator of Disease Resistance Through the SA‐Dependent Pathway

open access: yesPlant Biotechnology Journal, EarlyView.
ABSTRACT Although microRNA1447 (miR1447) regulates poplar responses to abiotic stress and pest infestation, how miR1447 regulates poplar immunity against pathogens and its underlying molecular mechanisms remain to be elucidated. Here, we revealed that miR1447 functioned as a negative regulator of poplar disease resistance against fungal and bacterial ...

Hydrogen Gas Enhances Salinity Tolerance in Tomato Seedlings by Regulating the S‐Nitrosylation of MEK1

open access: yesPlant Biotechnology Journal, EarlyView.
ABSTRACT Hydrogen gas (H2) effectively alleviates abiotic stress in horticultural plants. Protein S‐nitrosylation, a key post‐translational modification, serves as a critical mechanism for nitric oxide (NO) to exert its biological function under adverse conditions.
