Sažetak
Rounded plates are a widely spread type of crystalline inclusions of the cucumber green mottle mosaic virus (CGMMV) and the ondotoglossum ringspot virus (ORSV). They appear a few days after infection and persist for quite a long time. Inclusions are built of one or more rounded disks of different size which are stacked one above the other. This structure can be established by examining the inclusions in side and in face view in a light microscope. Observations in polarized light and treatments with acids exhibit that the virus particles are oriented perpendicularly to the flat surface of the plates.
Inclusions similar in appearance to the hexagonal prisms of the tobacco mosaic virus (TMV) or the tomato mosaic virus (ToMV) also develop in cells infected with CGMMV and ORSV but they are rather thin and usually do not have a typical hexagonal shape. They are connected with rounded plates by a number of intermediate forms.
The rounded plates are very frequent inclusions in the group of Tomoviruses (= the group of the tobacco mosaic virus) because they also occur in the cells infected by the sunn hemp mosaic virus (SHMV; syn. bean form of TMV) and Holmes’ ribgrass virus (HRV).
