Abstract
A 27-nm icosahedral virus was purified from the oat bird cherry aphid, Rhopalosiphum padi (L.). The virus had an s(20,w) of 162 +/- 2 S, and bouyant densities of 1.37 in CsCl and 1.35 in Cs2SO4. It contained one ssRNA of 31 +/- 2 S and three major proteins. The relationship of the R. padi virus to other small RNA invertebrate viruses is unclear.
摘要
从燕麦缢管蚜（Rhopalosiphum padi (L.)）中纯化出一种27纳米的二十面体病毒。该病毒的沉降系数s(20,w)为162±2 S，在CsCl中的浮力密度为1.37，在Cs2SO4中的浮力密度为1.35。它含有一个31±2 S的单链RNA和三种主要蛋白质。燕麦缢管蚜病毒与其他小型RNA无脊椎动物病毒的关系尚不清楚。
