Abstract

A potexvirus, silene virus X (SVX), was isolated from the weed Silene pratensis. Infectious preparations contained nucleoprotein rods predominantly 546 nm in length, consisting of a 6.9-kb polyadenylated single-stranded RNA and a 29-kd capsid protein. Double-stranded RNAs of 17.1, 7.0, 5.7, and 4.6 kbp were isolated from SVX-infected plants. In vitro translation products of SVX single-stranded or denatured double-stranded RNAs reacted with SVX antiserum. Hybridization studies with SVX cDNAs showed no nucleotide homology with seven other potexviruses. The virus is more closely related serologically to narcissus mosaic virus than to nine other potexviruses.

摘要

一种马铃薯X病毒属病毒，即麦瓶草病毒X（SVX），是从杂草草地麦瓶草中分离出来的。感染性制剂含有主要长度为546纳米的核蛋白棒，由一条6.9千碱基的多聚腺苷酸化单链RNA和一种29千道尔顿的衣壳蛋白组成。从感染SVX的植物中分离出了17.1、7.0、5.7和4.6千碱基对的双链RNA。SVX单链或变性双链RNA的体外翻译产物与SVX抗血清发生反应。用SVX cDNA进行的杂交研究表明，它与其他七种马铃薯X病毒没有核苷酸同源性。与其他九种马铃薯X病毒相比，该病毒在血清学上与水仙花叶病毒的关系更为密切。
