The Manifestation of the Dual ROS-Processing and Redox Signaling Roles of Glutathione Peroxidase-like Enzymes in Development of Arabidopsis Seedlings Open
Plant glutathione peroxidase-like (GPXL) enzymes are thiol-based peroxidases that reduce H2O2 or hydroperoxides to water or alcohols using electrons principally from thioredoxin. Arabidopsis thaliana possesses eight isoenzymes (AtGPXL1−8) …

Glutathione Transferases Are Involved in the Genotype-Specific Salt-Stress Response of Tomato Plants Open
Glutathione transferases (GSTs) are one of the most versatile multigenic enzyme superfamilies. In our experiments, the involvement of the genotype-specific induction of GST genes and glutathione- or redox-related genes in pathways regulati…

Contribution of Glutathione Transferases in the Selective and Light-Dependent Effect of Flumioxazin on Winter Wheat (Triticum aestivum L.) and Its Typical Weed Common Poppy (Papaver rhoeas L.) Open
Glutathione transferases (GSTs) are enzymes that catalyse modifications and conjugations of a range of organic and often cytotoxic compounds. GST enzymes with many functions—such as their conjugation activity against herbicides and their m…

Glutathione Transferases are Involved in Salicylic Acid-Induced Transcriptional Reprogramming Open
Salicylic acid (SA) plays a crucial role not only in defence against pathogen attacks, but also in abiotic stress responses. Recently, some key steps of SA signalling outlined the importance of redox state-dependent processes. This study e…

AtGSTU19 and AtGSTU24 as Moderators of the Response of Arabidopsis thaliana to Turnip mosaic virus Open
Plants produce glutathione as a response to the intercellular redox state. Glutathione actively participates in the reactive oxygen species (ROS)-dependent signaling pathway, especially under biotic stress conditions. Most of the glutathio…

Plant Glutathione Peroxidases: Non-Heme Peroxidases with Large Functional Flexibility as a Core Component of ROS-Processing Mechanisms and Signalling Open
Glutathione peroxidases (GPXs) are non-heme peroxidases catalyzing the reduction of H2O2 or organic hydroperoxides to water or corresponding alcohols using glutathione (GSH) or thioredoxin (TRX) as a reducing agent. In contrast to animal G…

Crosstalk between the Arabidopsis Glutathione Peroxidase-Like 5 Isoenzyme (AtGPXL5) and Ethylene Open
Glutathione peroxidases (GPXs) are important antioxidant enzymes in animals. Plants contain GPX-like (GPXL) enzymes, which—in contrast to GPXs—contain cysteine in their active site instead of selenocysteine. Although several studies proved…

Systemic response to Fusarium graminearum and culmorum inoculations: changes in detoxification of flag leaves in wheat Open
Fusarium graminearum and F. culmorum cause the most widespread wheat disease Fusarium head blight (FHB). The present study describes that the Fusarium inoculation of the wheat spikes caused systemic changes in the key elements of the antio…

Compensation of Mutation in Arabidopsis glutathione transferase (AtGSTU) Genes under Control or Salt Stress Conditions Open
Glutathione transferases (GSTs) play a crucial role in detoxification processes due to the fact of their glutathione (GSH) conjugating activity, and through glutathione peroxidase or dehydroascorbate reductase (DHAR) activities, they influ…

Plant Glutathione Transferases and Light Open
The activity and expression of glutathione transferases (GSTs) depend on several less-known endogenous and well-described exogenous factors, such as the developmental stage, presence, and intensity of different stressors, as well as on the…
