Abstract
A single kind of double-stranded RNA (dsRNA) with apparent MW of 3.6 .times. 106 daltons was detected in isolates of G. candidum by agarose gel electrophoresis. The dsRNA molecule was present in 8 of 10 isolates of the citrus sour rot pathogen but absent in nonpathogenic isolates of G. candidum. Isodiametric (.apprx. 40 nm) viruslike-particles (VLP) were studied from a pathogenic isolate. The dsRNA molecule of viral origin was identical in molecular size to the dsRNA obtained directly from cells. Two virus-associated proteins with estimated MW of .apprx. 94,000 and 71,000, daltons were characterized by SDS polyacrylamide electrophoresis.This publication has 8 references indexed in Scilit:
