Abstract
Leaf tissue of Tetragonia expansa Thunb. and of Maclura pomifera (Raf.) Robinson plants infected with maclura mosaic virus (MacMV) was studied by light and electron microscopy.
In the cytoplasm of the epidermal cells of T. expansa amorphous granular inclusion bodies were commonly observed with the light microscope.
Submicroscopic cytoplasmic lamellar inclusions in infected T. expansa and M. pomifera cells included the same forms (pinwheels and laminated aggregates) as those observed in plants infected with viruses belonging to subdivision II of potyviruses (Edwardson 1974).
In T. expansa another type of submicroscopis virus inclusions was also established. These are the extraprotoplasmic membrane-bound aggregates of virus particles or the so-called micro-inclusion bodies (Krass and Ford 1969) situated outside the cytoplasm, i. e. between the plasmalemma and the cell wall. A possible role of these structures as the mechanism for localizing a virus infection is discussed.
