The photosynthetic organelle of algae and plants (the plastid) traces its origin to a primary endosymbiotic event in which apreviously non-photosynthetic protist engulfed and enslaved a cyanobacterium. This eukaryote then gave rise to the red, green and glaucophyte algae. Endosymbiotic Theory 44 relat...

Besides, to formulate the prokaryote/eukaryote distinction, a catalogue of structure-functional characteristics of anucleate/nucleate cells is needed that substitutes for a conceptual definition (Cavalier-Smith, 1981). To overcome these restrictions, a novel subdivision of cell morphotype...

Most currently used antibiotics originate from Streptomycetes and phosphate limitation is an important trigger of their biosynthesis. Understanding the molecular processes underpinning such regulation is of crucial importance to exploit the great metabol
A number of the glycolytic enzymes ofTrimastixhave been transferred laterally from bacteria instead of being inherited from the last common eukaryotic ancestor. Thus, despite widespread conservation of the glycolytic biochemical pathway across eukaryote diversity, in a number of protist lineages the enzyma...
