| Abstract:
Typical flexuous rod particles of cymbidium mosaic virus (CyMV) were observed in negatively stained preparations and in thin-sections of Cattleya leaves systematically infected with CyMV. Intracellular inclusions and loosely scattered individual virus particles were abundant in the cytoplasm. The inclusions consisted of aggregates of flexuous rod-shaped particles and were variable in shape and size, and often formed stacks of banded inclusions in the cytoplasm. The morphology and orientation of the inclusions were more or less similar to those of other members of the potex virus group. Chloroplasts in the infected cells were abnormally swollen, containing large starch grains and osmiophillic bodies. Characteristic aggregation of ribosomes, several in number, was observed at some stages of infection. | |
