The Spitzenkörper: a choreographer of fungal growth and morphogenesis

- The Spitzenkörper (SPK) is a highly ordered structure of hyphal apices.
- The SPK determines hyphal growth and morphogenesis.
- Neurospora crassa provides insight into the organization of the fungal SPK.
- The main constituents of the SPK are vesicles, actin and ribosomes.
- Macrovesicles and microvesicles contain different cell wall synthetic functions.
