SOME PROPERTIES OF A DISTINCTIVE ISOMETRIC VIRUS FROM PELARGONIUM |
| Authors: | N. Pleše, Z. Štefanac |
| Abstract:
An isometric virus about 30 nm in diameter was isolated from two cultivars of Pelargonium zonale with yellow/green spots and leaf deformations expressed during the winter. It infected 18 of 21 common test plants used in some of which it induced formation of characteristic amorphous inclusion bodies. The virus was readily transmitted by inoculation of sap, but not by Myzus persicae given short feeding times. The preliminary test did not suggest seed transmission to be likely. Infectivity survived for 10 min at 80°C, up to 18 days at 24°C, and was lost at dilution greater than 10–5. The virus did not react with sera against sixteen isometric viruses including pelargonium flower-break, pelargonium ring-pattern, and pelargonium ringspot. However, it did react with serum against a distinctive pelargonium virus briefly reported by Stone and Hollings (1977). | |
