TL;DR: Alternative, non-cyclic flux modes occur in leaves in the light, in some developing oilseeds, and under specific physiological circumstances such as anoxia.

TL;DR: In this paper, the authors reviewed the available literature and experimental evidence from own experiments and concluded that no mechanism on its own provides an adequate explanation of the available data, and that ammonium toxicity is the result of one or more of the following effects: ammonium-induced mineral nutrient deficiency, arising from the impaired uptake of metal ions; secondary growth inhibition arising from acidification of the rooting medium; alterations in intracellular pH and osmotic balance; uncoupling of photophosphorylation from electron transport, following the accumulation of ammonium in leaves; and altered

TL;DR: It is shown that the repression of this mitochondrially localized enzyme improves both carbon assimilation and aerial growth in a crop species.

TL;DR: In this paper, the authors showed that tomato (Solanum lycopersicum) plants expressing a fragment of a fumarate hydratase (fumarase) gene in the antisense orientation and exhibiting considerable reductions in the mitochondrial activity of this enzyme show impaired photosynthesis.

TL;DR: It appears that glycolytic enzymes associate dynamically with mitochondria to support respiration and that substrate channeling restricts the use of intermediates by competing metabolic pathways.
