Other claims from this paper (9)
- Observation Particle distribution and ultrastructural effects tracked host-virus severity more than virus or host species.
- Observation Cocksfoot mottle virus particles occasionally occurred in nuclei.
- Observation Mildly symptomatic plants had relatively few randomly distributed cytoplasmic particles.
- Observation Severely symptomatic plants had numerous particles, often in crystalline aggregates.
- Observation In partially disrupted cells, particles sometimes occurred in membrane-bound vacuolar packets.
- Observation In more severely disrupted cells the tonoplast was absent and particles scattered through the vacuole.
- Observation Cell damage ranged from greater endoplasmic reticulum and vacuolation under mild symptoms to complete organelle disintegration under severe symptoms.
- Observation Extrusions developed from chloroplasts and mitochondria.
- Observation Membrane-bound vesicles containing viral particles appeared in chloroplast stroma and mitochondria.
