The Occurrence of a Rhabdovirus in Daphne mezereum in the Czech Republic

A virus detected in symptomless Daphne mezereum L. plants in the Czech Republic had bacilliform virions which, in thin sections, measured 162±215 nm by 62± 75 nm. They occurred mostly in the parenchymatous cells of vascular bundles and cambium, and were located in perinuclear spaces and within cisternae of the endoplasmic reticulum, either singly or in aggregates; occasionally, isolated particles or particle aggregates were seen within the nuclei. This is the ®rst record of a rhabdovirus occurring in daphne.
