Abstract
The Kazakhstan strain of TMV was described first by Goldin (1963). Later Break (1978) established that this virus resembled defective TMV strains, mainly on the basis of the presence of very long particles in the preparations made by dipping method.
This virus builds various types of crystalline inclusion bodies in cells, especially elongated crystals with striations and long coiled fibres (Fig. 1). Elongated crystals are similar to spikes and are present in the cytoplasm and in the nucleus.
In this study inclusion bodies were examined by electron microscope and it was found that the inclusions, at least sometimes, are not built of complete virus particles but of structures which are named stretched threads. These structures represent a kind of fibrils which are difficult to stain, have a diameter of about 90 Â and are parallelly arranged (Fig. 3 and 4). It would be important to solve the problem from which chemical material the stretched threads are built.
