The study of plant mitochondria started in earnest around 1950 with the first isolations of
mitochondria from animal and plant tissues. The first 35 years were spent establishing the …

Ascorbic acid is synthesised by eukaryotes, the known exceptions being primates and some
other animal groups which have lost functional gulonolactone oxidase. Prokaryotes do not …

Vitamin C (l-ascorbic acid) is an excellent free radical scavenger, not only for its capability to
donate reducing equivalents but also for the relative stability of the derived …

Throughout evolution, a number of animals including humans have lost the ability to
synthesize ascorbic acid (ascorbate, vitamin C), an essential molecule in the physiology of …

Mitochondria are central to cellular metabolism and energy conversion. In plants they also
enable photosynthesis through additional components and functional flexibility. A majority of …

The respiratory electron transport chain (ETC) couples electron transfer from organic
substrates onto molecular oxygen with proton translocation across the inner mitochondrial …

Significance: The concept that vitamin C (l-ascorbic acid) is at the heart of the peroxide
processing and redox signaling hub in plants is well established, but our knowledge of the …

Abstract Mitochondrial Oxidative Phosphorylation (OXPHOS) provides ATP for driving
cellular functions. In plants, OXPHOS takes place in the context of photosynthesis. Indeed …

Ascorbic acid (vitamin C) is an enzyme co-factor in eukaryotes that also plays a critical role
in protecting photosynthetic eukaryotes against damaging reactive oxygen species derived …

Abstract Significance: Reduction-oxidation (Redox) status operates as a major integrator of
subcellular and extracellular metabolism and is simultaneously itself regulated by metabolic …
