The extent to which non-host-associated bacterial communities exhibit small-scale biogeographic patterns in their distribution remains unclear. Our investigation of biogeography in bacterial community ...

Plants prevent dehydration by coating their aerial, primary organs with waxes. Wax compositions frequently differ between species, organs, and developmental stages, probably to balance limiting ...

Plastoglobuli have been isolated and purified from chloroplasts of beech and spinach leaves and from broom flower chromoplasts by a repeated floating-gradient technique. The main components in ...

Exosomes are saucer-shaped vesicles of 30–100 nm in diameter, which are delimited by a lipid bi-layer and which float at a density of 1.13–1.19 g ml −1 in sucrose gradients. These vesicles are ...
