Presence of 175 kDa myosin in isolated phragmoplasts. (A) Immunoblotting of isolated phragmoplasts was carried out using antibody against actin (b), tubulin (c), 175 kDa (d), or 170 kDa myosin heavy chain (e). Actin, tubulin, and the 175 kDa myosin, but not 170 kDa myosin, were present in the isolated phragmoplasts. (a) CBB-stained 8% SDS–polyacrylamide gel. The molecular masses of standard proteins are indicated on the left in kilodaltons. (B) Double immunofluorescence staining of isolated phragmoplasts with the antibody against 175 kDa myosin heavy chain (a and d) and RP (b and e). The 175 kDa myosin (a) was concentrated at the boundary between the opposite actin filament bundles (arrow in b) in the isolated phragmoplast. (c) Merged image of a and b. In the view from the pole, the 175 kDa myosin (d) was co-localized with the actin filament ring of the isolated phragmoplast (e). The bar represents 20 μm.
