Abstract
Ultrathin sections through the leaf tissue of ornamental shrubs Euonymus japonica Thunb. suffering from mosaic disease (Japanese spindle-tree mosaic) and of symptomless ones were analysed by electron microscopy. Elongated particles of a filamentous virus were present in the cytoplasm of the parenchyma cells of all shrubs displaying mosaic. The particles about 650 to 680 nm long and 18 nm thick were randomly distributed or laterally aggregated forming small bundles scattered in the cytoplasm.
We consider that this filamentous virus, apparently wide-spread in E. japonica in the inland part of Croatia (Zagreb), is the agent which causes Japanese spidle-tree mosaic.
