Abstract
Inclusions in cells of Nicotiana glutinosa infected with a horse-radish strain of cabbage black ring virus (CBRV) were investigated on ultrathin sections. Large amorphous inclusions contained cellular constituents showing usually no pathological alterations. Lamellar inclusions (bundles, circular inclusions, pinwheels), closely associated with endoplasmic reticulum, occurred frequently in areas of cytoplasm showing no vesiculation. Sac-like structures composed of concentric lamellae were observed in the cytoplasm or intruding into the vacuole. Spherosomes each containing a single crystal were found very often in the cytoplasm. Masses of virus particles in a parallel arrangement were usually located at the tonoplast.
