Sažetak
Virus inclusion bodies of four isolates of broad bean wilt virus (BBWV) were investigated with light and electron microscope. Two virus isolates derived from Yugoslavia and two isolates from the German Democratic Republic. All these isolates ordinarily formed a large number of amorphous inclusions (X-bodies) the fine structure of which is characteristic of BBWV infections.
The first Yugoslav isolate from Vicia faba provoked three forms of crystalline inclusions. Because of this and other properties, it was obvious that it belonged to the nasturtium strain which is wide spread in this country. The second Yugoslav isolate from Digitalis ferruginea contained only one form of crystalline bodies, i. e. the polyhedral crystals. This species is a new natural host of BBWV.
The first German isolate from Celsia arcturus is very similar to the strain of BBWV which is common in Germany. It produced spindle- and needle-like crystals in the cytoplasm of infected cells and polyhedral crystals in the vacuole. The fine structure of needle-like virus crystals was described; it differed somewhat from the structure of elongated crystals. The second German isolate from Galvezia speciosa corresponded according to the inclusions in infected cells to the first German isolate, except for the polyhedral crystals which were not present.
