Alternative or cytochrome? Respiratory pathways in traps of aquatic carnivorous bladderwort Utricularia reflexa

Plant Signaling & Behavior, 2022
Carnivorous plants of the genus Utricularia (bladderwort) form modified leaves into suction bladder traps. The bladders are metabolically active plant tissue with high rates of mitochondrial respiration (RD).

Nitric Oxide Turnover Under Hypoxia Results in the Rapid Increased Expression of the Plastid-Localized Phosphorylated Pathway of Serine Biosynthesis

Frontiers in Plant Science, 2022
The plant mitochondrial electron transport chain influences carbon and nitrogen metabolism under near anoxic conditions through its involvement in the phytoglobin-nitric oxide cycle, where the respiratory chain reduces nitrite to nitric oxide (NO ...

Evaluation of some defense enzymes activities in chickpea plants under cold stress [PDF]

مجله بیوتکنولوژی کشاورزی, 2017
Plants require different defensive mechanisms for being survive and tolerance to environmental stresses. In present study, activity of defensive enzymes such as alternative oxidase (AOX), superoxide dismutase (SOD), catalase (CAT), electrolyte leakage ...

Role of Glutathione-Ascorbate Cycle and Photosynthetic Electronic Transfer in Alternative Oxidase-Manipulated Waterlogging Tolerance in Watermelon Seedlings

Horticulturae, 2021
Alternative oxidase (AOX) has been documented to mitigate the oxidative stress caused by abiotic stresses. However, it remains unknown how AOX regulates the antioxidant system and photosynthesis under waterlogging.

Characterization of Single Gene Deletion Mutants Affecting Alternative Oxidase Production in Neurospora crassa: Role of the yvh1 Gene

Microorganisms, 2020
The Neurospora crassa AOD1 protein is a mitochondrial alternative oxidase that passes electrons directly from ubiquinol to oxygen. The enzyme is encoded by the nuclear aod-1 gene and is produced when the standard electron transport chain is inhibited. We

Bypassing mitochondrial complex III using alternative oxidase inhibits acute pulmonary oxygen sensing

Science Advances, 2020
Signaling from the mitochondrial respiratory chain is essential for acute vascular oxygen sensing in the lung. Mitochondria play an important role in sensing both acute and chronic hypoxia in the pulmonary vasculature, but their primary oxygen-sensing ...

An Essential Role of Mitochondrial α-Ketoglutarate Dehydrogenase E2 in the Basal Immune Response Against Bacterial Pathogens in Tomato

Frontiers in Plant Science, 2020
Plants intensely modulate respiration when pathogens attack, but the function of mitochondrial respiration-related genes in plant–bacteria interaction is largely unclear.

A Broad Distribution of the Alternative Oxidase in Microsporidian Parasites [PDF]

PLoS Pathogens, 2010
Microsporidia are a group of obligate intracellular parasitic eukaryotes that were considered to be amitochondriate until the recent discovery of highly reduced mitochondrial organelles called mitosomes. Analysis of the complete genome of Encephalitozoon cuniculi revealed a highly reduced set of proteins in the organelle, mostly related to the assembly

Molecular Biology of the Alternative Oxidase [PDF]

Plant Physiology, 1994
Possibly the most easily recognized component of mitochondrial respiration specific to plants is a second terminal oxidase that has been variously described as being responsible for "cyanide-insensitive respiration," 'cyanide-resistant respiration," or "alternative pathway respiration.' This type of respiration has been best defined in thermogenic ...

Cytochrome oxidase: an alternative model. [PDF]

Proceedings of the National Academy of Sciences, 1980
Oxidative titration of reduced cytochrome oxidase (cytochrome c oxidase; ferrocytochrome c:oxygen oxidoreductase, EC 1.9.3.1) in the presence of carbon monoxide and sulfide, at potentials greater than +500 mV (vs. the neutral hydrogen electrode), have failed to produce new copper signals in the electron paramagnetic resonance spectrum of this enzyme ...
