PbrIDD2‐PbrAPX14 Module Functions in the Ethylene‐Mediated Ripening and Senescence Process of Pear Fruit

Plant Biotechnology Journal, EarlyView.
ABSTRACT Endogenous H2O2 participated in the ethylene‐dependent ripening and senescence process of horticultural fruit as a secondary messenger; however, the molecular mechanism beneath such a phenomenon has not been fully clarified until recently. By a conjoint analysis of metabolite, enzyme activities, gene expression profiles in AsA‐GSH cycle of ...

The Circadian Oscillator Affects Both Glutathione Homeostasis and Its Response to Salt Stress in Arabidopsis thaliana

Plant, Cell &Environment, EarlyView.
ABSTRACT Glutathione, including reduced glutathione (GSH) and oxidized glutathione (GSSG), is the major non‐protein thiol‐based redox buffer. There are diurnal rhythms in total glutathione level and in this work, we investigate whether these oscillations might be indicative of circadian regulation of total glutathione homeostasis.

Subcellular localization of a glutathione-dependent dehydroascorbate reductase within specific brain regions

, 2001
Recently, we described the occurrence of a dehydroascorbate reductase within the rat CNS. This enzyme regenerates ascorbate after it is oxidized during normal aerobic metabolism.

Molecular Chaperone Networks in Plants: Maintaining Proteostasis and Enhancing Stress Resilience for Crop Improvement

Plant, Cell &Environment, EarlyView.
ABSTRACT Molecular chaperones play a central role in the plant proteostasis machinery by aiding the folding of nascent proteins, preventing aggregation, and repairing or degrading damaged proteins. These functions are especially essential during abiotic and biotic stress, which can destabilise cellular proteins and disrupt metabolic homoeostasis.

Hydrogen sulfide is involved in the regulation of ascorbate and glutathione metabolism by jasmonic acid in Arabidopsis thaliana

Biologia Plantarum, 2018
This study investigated the role of hydrogen sulfide (H2S) in the regulation of the ascorbate (AsA) and glutathione (GSH) metabolism by jasmonic acid (JA) in the leaves of Arabidopsis thaliana by using H2S scavenger hypotaurine (HT) and H2S synthetic ...

Integrated Multi‐Omic Analyses Uncover a Regulatory Link Between Photosynthesis and Drought Tolerance in Field‐Grown Sorghum

Plant, Cell &Environment, EarlyView.
ABSTRACT Global warming and increasing water scarcity pose major challenges to agriculture, emphasising the need to translate stress‐biology insights into the development of drought‐resilient cultivars. In this study, we evaluated a panel of six diverse sorghum (Sorghum bicolour) accessions grown under field‐imposed drought conditions in central ...

The Apoplastic and Symplastic Antioxidant System in Onion: Response to Long-Term Salt Stress

Antioxidants, 2020
The response of apoplastic antioxidant systems in root and leaf tissues from two onion genotypes (‘Texas 502’, salt-sensitive and ‘Granex 429’, salt-resistant) in response to salinity was studied.

Time‐ and cultivar‐dependent biochemical responses to heat priming and stress in rice

Annals of Applied Biology, Volume 189, Issue 1, July 2026.
Global warming increasingly threatens rice productivity, and understanding the biochemical mechanisms underlying heat stress responses is crucial for developing resilient cultivars. By demonstrating that stress responses are both cultivar‐ and time‐of‐day‐dependent, our findings offer new insights into the temporal and genetic regulation of acquired ...

Dehydroascorbate reduction: The phantom remaining

, 1998
In our recent contribution [1]we questioned the role of dehydroascorbate (DHA) and DHA reductase as reliable indicators of oxidative stress in plants.
