Cellular Subcompartments through Cytoplasmic Streaming.
Cytoplasmic streaming occurs in diverse cell types, where it generally serves a transport function. Here, we examine streaming in multicellular fungal hyphae and identify an additional function wherein regimented streaming forms distinct cytoplasmic subcompartments. In the hypha, cytoplasm flows directionally from cell to cell through septal pores. Using live-cell imaging and computer simulatio...
متن کاملCytoplasmic streaming in plants.
Plant cells are surrounded by a cell wall composed of polysaccharides and hence can change neither their form nor their position. However, active movement of organelles (cytoplasmic streaming or protoplasmic streaming) is observed in plant cells, and involvement of the actin/myosin system in these processes has been suggested. Successful biochemical and biophysical approaches to studying myosin...
متن کاملMicrofilaments and cytoplasmic streaming: inhibition of streaming with cytochalasin.
Cytochalasin B reversibly inhibits cytoplasmic streaming in both Nitella and Avena cells. Colchicine, on the other hand, has no effect on streaming in either plant; nor does colchicine prevent the recovery of streaming after cytochalasin is withdrawn. The inhibition of protein synthesis by cycloheximide has no effect on either streaming itself or on the recovery of streaming after cytochalasin ...
متن کاملEffects of Exogenous Proteins on Cytoplasmic Streaming
Cytoplasmic streaming in characean algae is thought to be generated by interaction between subcortical actin bundles and endoplasmic myosin . Most of the existing evidence supporting this hypothesis is of a structural rather than functional nature . To obtain evidence bearing on the possible function of actin and myosin in streaming, we used perfusion techniques to introduce a number of contrac...
