Due to the sessile nature of plants, it is crucial for their survival and growth that they can handle a constantly changing, and thus stressful, ambient environment by modifying their structure and metabolism. The central metabolism of plants is characterized by many alternative options for metabolic pathways, which allow a wide range of adjustments of metabolic processes in response to environmental...
The electron transport chain in mitochondria of different organisms contains a mixture of common and specialised components. The specialised enzymes form branches to the universal electron path, especially at the level of ubiquinone, and allow the chain to adjust to different cellular and metabolic requirements. In plants, specialised components have been known for a long time. However, recently,...
Plasmalemma vesicles from wheat (Triticum aestivum L.) roots consumed O 2 and the addition of 1 mM NADH increased the rate ~ 3-fold (to 15-30 nmol O 2 .mg -1 .min -1 ). The NADH-dependent O 2 uptake was abolished by catalase. In the presence of salicylhydroxamic acid (SHAM), an inhibitor of the alternative oxidase pathway in plant mitochondria, NADH-dependent...
