PRO40 (IMAGE) Ruhr-University Bochum Caption Just like in humans, in fungi, too, fusions between cells are crucial for their development. In the hyphae fungus Sordaria macrospora such fusions (arrow) are required for the production of fruiting bodies during sexual development. The scaffold protein PRO40 is essential for these processes.
