Abstract

Isolation and some properties of Pelargonium vein clearing virus.

Abstract

The virus was sap transmitted to herbaceous indicator plants. Except for Gomphrena globosa, which was locally infected, the host range was limited to Solanaceae. Expressed sap of Nicotiana glutinosa lost infectivity at a dilution of 10-6, after heating 10 min at 60 deg C and after storage for 2 days at room temp. The virus is a rhabdovirus with nuclear maturation. Mature particles are bacilliform and measure 250 X 70 nm. The ultrastructure of infected cells and the morphological characteristics of the virions conform to those reported for other plant rhabdoviruses.
