Implication of S-Lactoylglutathione in the Spontaneous Cysteine S-Glutathionylation and Lysine N-Lactoylation of Arabidopsis thaliana NAD-Dependent Glyceraldehyde 3P Dehydrogenase Open
In this study, the involvement of S,D-lactoylglutathione in the modification of the iso-form 1 of cytosolic glyceraldehyde 3P dehydrogenase (GAPC1) is examined. Incuba-tion of GAPC1 with S,D-lactoylglutathione resulted in inhibition of enz…

The role of alternative oxidase in the maintenance of cellular redox balance under hypoxia via participation in nitric oxide turnover Open
Alternative oxidase (AOX) regulates the level of reactive oxygen species and nitric oxide (NO) in plants. While it alleviates NO formation under normoxic conditions, there are several indications that in conditions of low oxygen, such as d…

Redox Control of Seed Germination is Mediated by the Crosstalk of Nitric Oxide and Reactive Oxygen Species Open
Significance: Seed germination and seedling establishment are characterized by changes in the intracellular redox state modulated by accelerated production of nitric oxide (NO) and reactive oxygen species (ROS). Redox regulation and enhanc…

Diversity of transgene integration and gene-editing events in wheat (Triticum aestivum L.) transgenic plants generated using Agrobacterium-mediated transformation Open
Improvement in agronomic traits in crops through gene editing (GE) relies on efficient transformation protocols for delivering the CRISPR/Cas9-coded transgenes. Recently, a few embryogenesis-related genes have been described, the co-delive…

Mitochondria in photosynthetic cells: Coordinating redox control and energy balance Open
In photosynthetic tissues in the light, the function of energy production is associated primarily with chloroplasts, while mitochondrial metabolism adjusts to balance ATP supply, regulate the reduction level of pyridine nucleotides, and op…

Metabolic Changes in Seed Embryos of Hypoxia-Tolerant Rice and Hypoxia-Sensitive Barley at the Onset of Germination Open
Rice (Oryza sativa L.) and barley (Hordeum vulgare L.) are the cereal species differing in tolerance to oxygen deficiency. To understand metabolic differences determining the sensitivity to low oxygen, we germinated rice and barley seeds a…

Roles for Plant Mitochondrial Alternative Oxidase Under Normoxia, Hypoxia, and Reoxygenation Conditions Open
Alternative oxidase (AOX) is a non-energy conserving terminal oxidase in the plant mitochondrial electron transport chain (ETC) that has a lower affinity for oxygen than does cytochrome (cyt) oxidase. To investigate the role(s) of AOX unde…

Matrix Redox Physiology Governs the Regulation of Plant Mitochondrial Metabolism through Posttranslational Protein Modifications Open
Mitochondria function as hubs of plant metabolism. Oxidative phosphorylation produces ATP, but it is also a central high-capacity electron sink required by many metabolic pathways that must be flexibly coordinated and integrated. Here, we …

Arabidopsis thaliana alcohol dehydrogenase is differently affected by several redox modifications Open
In plant cells, many stresses, including low oxygen availability, result in a higher production of reactive oxygen species (ROS) and reactive nitrogen species (RNS). These molecules can lead to redox-dependent post-translational modificati…
