Abstract

A cucumber mosaic virus (CMV) isolate supporting a natural 390-ribonucleotide satellite was used to reproduce under experimental conditions a disease of processing tomatoes called fruit necrosis. The virus induced incomplete differentiation of the vascular tissue of fruit stalks, which was the likely cause of the disease. On the other hand, the satellite RNA attenuated viral symptoms on tomato leaves reproducing the disease pattern typically observed in the field. The biological properties of this seemingly new variant of cucumoviral satellite RNAs were determined.

摘要

一株携带天然390个核糖核苷酸卫星RNA的黄瓜花叶病毒（CMV）分离株，被用于在实验条件下重现一种加工番茄病害——果实坏死。该病毒导致果柄维管组织分化不完全，这可能是该病的病因。另一方面，卫星RNA减轻了番茄叶片上的病毒症状，重现了田间通常观察到的病害模式。确定了这种黄瓜花叶病毒卫星RNA看似新变种的生物学特性。
