The juxtaposition of highly productive coral reef ecosystems in oligotrophic waters has
spurred substantial interest and progress in our understanding of macronutrient uptake …

Iron (Fe) homeostasis is essential for life and has been intensively investigated for dicots,
while our knowledge for species in the Poaceae is fragmentary. This study presents the first …

Abstract b-Type cytochromes (cyts) are a class of redox proteins well known from electron-
transport chains found in mitochondria, chloroplasts and bacterial cell membranes. Their …

Electron transport processes are mainly associated with photosynthesis and respiratory
chain. Nowadays the occurrence and possible roles of electron transport systems in plant …

The plasma membrane (PM) redox studies started in the 1920s by measuring the reduction
rate of impermeable redox dyes (eg. indigodisulfonate) by normal and tumor cells (Crane et …

This chapter will describe a novel plasma membrane iron transport system that is used by
both the budding yeast Saccharomyces cerevisiae. and the fission yeast …

The present study reveals the relationship between copper uptake and cupric-chelate
reductase activity alteration as well as the copper effects on ferric-chelate reduction and …

Tanto el hierro como el cromo forman en medios acuosos iones en estado de oxidación 2+,
3+ y 6+; la oxidación del Cr (III) es más fácil y su reducción es más difícil en comparación …

To maintain an energized status of the cellular components a constant flow of electrons has
to be provided. Electron flow goes energetically downhill from reduced molecules (donors) …
