Abstract

A double-stranded RNA (ds RNA) with an approximate size of 4.7 kb was found in 6 Phytomonas isolates specifically associated with plant pathogenicity in coconut trees ("Hartrot" disease) and oil palm ("Marchitez sorpressiva" disease). This ds RNA was not detected in 10 non-pathogenic Phytomonas isolates from different lactiferous plants or in the insect trypanosomatids Crithidia and Herpetomonas. Analysis by electron microscopy of a sucrose gradient fraction containing this ds RNA revealed virus-like particles.

摘要

在6株与椰子树（“哈特罗病”）和油棕（“马奇泰兹·索普雷西瓦病”）植物致病性特别相关的植滴虫分离株中发现了一种大小约为4.7 kb的双链RNA（ds RNA）。在来自不同乳汁植物的10株非致病性植滴虫分离株或昆虫锥虫克氏锥虫和赫氏锥虫中未检测到这种ds RNA。对含有这种ds RNA的蔗糖梯度级分进行电子显微镜分析，发现了病毒样颗粒。
