Motoring along the hyphae: molecular motors and the fungal cytoskeleton.

This review discusses molecular motors that use the microfilament and microtubule cytoskeletal systems in filamentous fungi. There has been an explosion in our knowledge of kinesins over the past year, because of the integration of genetic and biochemical data. The recognition of possible interactions between septation genes and cytokinesis has also advanced our understanding of microfilament-based cytoskeletal systems. We review recent findings on microfilament motors, including conventional and unconventional myosins, and the microtubule motors of the kinesin family and cytoplasmic dynein. The roles that these molecules play in hyphal morphogenesis and organelle transport provide an insight into cytoskeletal-based transport systems.
