FIG 8.

TuMV particles are associated with electron-dense bodies. (A and B) In HPF/FS-prepared samples, virus-like particles are found as filament bundles associated with electron-dense bodies in the vicinity of TuMV-induced membranous aggregates at a late stage of infection (A), and the DMVL structures are found close to these filament bundle structures (B). (C) In chemically fixed samples, the filament bundles associated with electron-dense bodies are found in the cytoplasm near the tonoplast. CI, cytoplasmic inclusion body; DMVL, double-membrane vesicle-like structure; EDB, electron-dense body; P, particles; Pr, peroxisome; V, vacuole; rER, rough endoplasmic reticulum.
