Abstract
Pea seed-borne mosaic virus (PSbMV) was for the first time found in Yugoslavia last year. It was observed in the field and was also established in seed-lots of cultivars Sprinter, Stern, and Mingomark. The identification of the virus was ascertained by an analysis on herbaceous plants, its stability in vitro, serological properties, and transmissibility by seeds. It was also confirmed that PSbMV was able to produce amorphous X-bodies well visible in light microscope. By means of an electron microscope pin-wheel structures, bundles, circles, and scrolls were seen in the infected cells but never laminated aggregates. In addition to that, hexagonal deposits of crystalline protein built from relatively large particles were found in the cytoplasm of the diseased cells; these deposits were similar to those described by Hampton et al. (1973).
Another pea virus isolate which probably represents a strain of PSbMV is described in this paper. This virus is named pea latent strain (PLS) of PSbMV because it is mostly latent in pea. It does not cause the symptom of leaf rolling and stunting in infected peas but it often provokes the transient symptom of vein clearing. It builds rarely X-bodies visible in the light microscope but forms submicroscopic inclusion bodies in the form of typical pin-wheels. PLS differs from the type virus also by shorter stability in vitro and some other characteristics.
