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

open access: yesFrontiers 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]

open access: yesمجله 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

open access: yesHorticulturae, 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

open access: yesMicroorganisms, 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

Cytochrome oxidase: an alternative model. [PDF]

open access: yesProceedings 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 ...

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

open access: yesFrontiers 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.

Alternative final steps in berberine biosynthesis in Coptis japonica cell cultures [PDF]

open access: yes, 1988
In Coptis japonica cell cultures an alternative pathway has been discovered which leads from (S)-tetrahydrocolumbamine via (S)-canadine to berberine. The two enzymes involved have been partially purified.

Purification of active recombinant trypanosome alternative oxidase [PDF]

open access: yesFEBS Letters, 2003
Trypanosome alternative oxidase (TAO) is the terminal oxidase of the respiratory chain in long slender bloodstream forms of African trypanosomes. TAO is a cytochrome‐independent, cyanide‐insensitive quinol oxidase. These characteristics are distinct from those of the bacterial quinol oxidases, proteins that belong to the heme‐copper terminal oxidase ...

Molecular Biology of the Alternative Oxidase [PDF]

open access: yesPlant 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 ...

Salicylic Acid Can Induce Resistance to Plant Virus Movement

open access: yesMolecular Plant-Microbe Interactions, 1998
Salicylic acid (SA) treatment has recently been reported to inhibit replication of tobacco mosaic virus (TMV) in inoculated tissue. Furthermore, resistance is induced via a novel defensive signal transduction pathway sensitive to inhibition by ...
