New cell component important to tea and wine-making

Scientists have discovered where plants build tannins, complex chemicals used by plants for defence and protection. The source is the tannosome, a newly discovered organelle that is found in most land plants.

Mitochondrial cooperatives

Mitochondria, the organelles that supply the cell with energy, are highly dynamic and can link up to form complex tubular networks. A new study shows that this response can transiently compensate for a shortfall in energy ...

The origins of a genetic switch

Cilia, microscopic whip-like organelles that protrude from the surface of many cell types, are almost ubiquitous. They are present in all eukaryotes—organisms whose cells have a nucleus—and have diversified to perform ...

Keep your distance: Why cells and organelles don't get stuck

Biomembranes enclose biological cells like a skin. They also surround organelles that carry out important functions in metabolism and cell division. Scientists have long known in principle how biomembranes are built up, and ...

Evolution of a novel organelle in Animalia

Mitochondria and chloroplasts are descendants of bacteria that were engulfed by ancient unicellular organisms more than a billion years ago. During their evolution, many genes were transferred from ancestral organelles and ...
