Mitochondria isolated from the roots of barley (Hordeum vulgare L.) and rice (Oryza sativa L.) seedlings were capable of oxidizing external NADH and NADPH anaerobically in the presence of nitrite. The reaction was linked to ATP synthesis and nitric oxide (NO) was a measurable product. The rates of NADH and NADPH oxidation were in the range of 12–16 nmol min−1 mg−1 protein for both species. The anaerobic ATP synthesis rate was 7–9 nmol min−1 mg−1 protein for barley and 15–17 nmol min−1 mg−1… 
Plant mitochondrial function during anaerobiosis.
Anaerobic mitochondrial metabolism may have a more significant role than previously thought in alleviating the effects of anoxia on plant cells, and there is a need to re-examine mitochondrial carbon and nitrogen metabolism under anoxIA to establish the extent of this involvement.
Nitric oxide inhibits succinate dehydrogenase-driven oxygen consumption in potato tuber mitochondria in an oxygen tension-independent manner.
SNAP inhibited PTM (potato tuber mitochondria) respiration independently of oxygen tensions, indicating a different kinetic mechanism from that observed in mammalian mitochondria, and suggests that SDH has an alternative site of NO action in plant mitochondria.
Reactive Nitrogen Species in Mitochondria and Their Implications in Plant Energy Status and Hypoxic Stress Tolerance
Plant mitochondria adapted the strategy to survive under hypoxia by keeping electron transport operative even without oxygen via the use of nitrite as a terminal electrons acceptor, and this overall operation represents an important strategy of biochemical adaptation that results in the improvement of energy status and thereby in protection of plants in the conditions of hypoxic stress.
The anoxic plant mitochondrion as a nitrite: NO reductase.
Inhibition of aconitase by nitric oxide leads to induction of the alternative oxidase and to a shift of metabolism towards biosynthesis of amino acids.
It is demonstrated that the NO produced in roots of wild-type plants inhibits aconitase which results in accumulation of citrate, the latter in turn inducing AOX and causing a shift of metabolism towards amino acid biosynthesis.
Involvement of nitrite in the nitrate-mediated modulation of fermentative metabolism and nitric oxide production of soybean roots during hypoxia
Results indicate that nitrite participates in the nitrate-mediated modulation of the fermentative metabolism of soybean roots during oxygen deficiency, and the involvement of mitochondrial reduction of nitrite to NO in this mechanism is discussed.
Hydroxylamine reduction to ammonium by plant and cyanobacterial hemoglobins.
The hypothesis that plant and cyanobacterial hemoglobins contribute to anaerobic nitrogen metabolism in support of an aerobic respiration and survival during hypoxia is supported.
Nitric Oxide Turnover Under Hypoxia Results in the Rapid Increased Expression of the Plastid-Localized Phosphorylated Pathway of Serine Biosynthesis
It is shown that high rates of NO turnover associate with rapid gene induction of the PPSB, establishing a clear link between this pathway and the maintenance of carbon, nitrogen and energy metabolism under hypoxia.


Denitrification, a Novel Type of Respiratory Metabolism in Fungal Mitochondrion*
Fungal denitrification activities are localized to mitochondria and are coupled to the synthesis of ATP with energy yields of 0.88 to 1.4, depending upon whether malate/pyruvate or succinate were provided as substrates.
Activities of isolated mitochondria and mitochondrial enzymes from aerobically and anaerobically germinated barnyard grass (echinochloa) seedlings.
The results suggest that mitochondria isolated from E. crus-galli var oryzicola differ from other plants studied and that the potential for mitochondrial function during anaerobiosis exists.
Effects of anoxia on mitochondrial biogenesis in rice shoots: modification of in organello translation characteristics.
Mitochondria were purified from aerobically germinated and anaerobically treated rice shoots by differential and isopycnic centrifugation and were found to consist of two subpopulations, which showed anaerobic mitochondria to be significantly different from aerobic mitochondria, with a matrix of lower density and more developed cristae.
NADH-dependent metabolism of nitric oxide in alfalfa root cultures expressing barley hemoglobin
The results are consistent with an NO dioxygenase-like activity, with hemoglobin acting in concert with a flavoprotein, to metabolize NO to nitrate utilizing NADH as the electron donor.

Mitochondrial enzymes in aerobically and anaerobically germinated seedlings of Echinochloa and rice
The data indicate that mitochondria of E. phyllopogon function better during anaerobiosis than those of rice and this factor may contribute to the successful “biochemical strategy” of this weed in rice paddies throughout the world.
Nitrate, NO and haemoglobin in plant adaptation to hypoxia: an alternative to classic fermentation pathways.
The role of nitrate reduction to produce nitric oxide (NO) and its subsequent oxidation by oxyhaemoglobin as a mechanism to maintain plant cell energetics during hypoxia is examined. Nitrate

Results indicate that exogenous nitrate exerts protective action as a terminal electron acceptor, alternative to the molecular oxygen, under anaerobic stress in wheat roots and rice coleoptiles.

Assays of several marker enzymes showed that the final mitochondrial preparations obtained are nearly free from other contaminating organelles, e.g. chloroplasts, peroxisomes, and endoplasmic reticulum.
