Cytoskeleton functions in plant–microbe interactions

Cytoskeleton-Secretory Vesicle Interactions

Stationary-phase cells of Paramecium tetraurelia have most of their many secretory vesicles ("trichocysts") attached to the cell surface. Log-phase cells contain numerous unoccuFiied potential docking sites for trichocysts and many free trichocysts in the cytoplasm. To study the possible involvement of cytoskeletal elements, notably of microtubules, in the process of positioning of trichocysts ...

Actin and microtubule cytoskeleton interactions.

Plant cytoskeleton consists of two major networks of protein polymers, actin microfilaments (AFs) and microtubules (MTs). These networks perform numerous functions that are essential for cell division and for maintaining the integrity of cytoplasm required for intracellular transport and cell shape. Besides the more or less indirect cooperation between AFs and MTs, their direct interactions thr...

Dendritic Actin Cytoskeleton: Structure, Functions, and Regulations

Actin is a versatile and ubiquitous cytoskeletal protein that plays a major role in both the establishment and the maintenance of neuronal polarity. For a long time, the most prominent roles that were attributed to actin in neurons were the movement of growth cones, polarized cargo sorting at the axon initial segment, and the dynamic plasticity of dendritic spines, since those compartments cont...

Cytoskeleton: Functions for tubulin modifications at last

New studies show that three types of evolutionarily conserved post translational tubulin modification, polyglutamylation, polyglycylation and detyrosination, play important roles in vivo. These modifications appear to act by modulating the binding of molecular motors to the external surface of microtubules.
