Neurons rely on a unique organization of their cytoskeleton to build, maintain and transform extraordinarily intricate shapes. After decades research the neuronal cytoskeleton, it is exciting that novel assemblies are still discovered thanks progress in cellular imaging methods. Indeed, super-resolution microscopy has revealed axons lined with periodic scaffold actin rings, spaced every 190 nm ...

The eukaryotic cytoskeleton evolved from prokaryotic cytomotive filaments. Prokaryotic filament systems show bewildering structural and dynamic complexity and, in many aspects, prefigure the self-organizing properties of the eukaryotic cytoskeleton. Here, the dynamic properties of the prokaryotic and eukaryotic cytoskeleton are compared, and how these relate to function and evolution of organel...

In pollen tubes, cytoskeleton proteins are involved in many aspects of pollen germination and growth, from the transport of sperm cells to the asymmetrical distribution of organelles to the deposition of cell wall material. These activities are based on the dynamics of the cytoskeleton. Changes to both actin filaments and microtubules are triggered by specific proteins, resulting in different o...
