cytoplasmastraling
Cytoplasmastraling is the directed movement of cytoplasm within a cell, resulting in the circulation of cytosol and cellular organelles. This process facilitates mixing of cytoplasmic contents and the rapid distribution of nutrients, signaling molecules, and membrane-bound vesicles. In many sources the term cytoplasmastraling is closely related to cytoplasmic streaming, and some authors treat it as a synonym or a broader description applied to larger-scale flows within cells.
Mechanistically, cytoplasmastraling is powered by cytoskeletal motors moving along filament tracks. In plant cells, actin filaments
Occurrences include large plant cells such as leaf cells and Characean algae, where cytoplasmastraling supports nutrient
Functional significance centers on efficient internal transport, mixing of metabolites, and signaling. Regulation involves calcium signaling,
Origin and terminology: the concept is traditionally described as cytoplasmic streaming in many plant biology texts;
