Abstract

In order to examine relationships among viruses of the bean yellow mosaic subgroup of the Potyvirus genus, several isolates of bean yellow mosaic virus (BYMV) and clover yellow vein virus (C1YVV) were compared by amino acid sequence of the coat protein and nucleotide sequence of the 3' terminal non-coding region. The sequence comparisons showed that BYMV and C1YVV were distinct viruses but had close affinity to each other (85-95% homology among isolates of a virus but 70-77% homology between viruses), justifying establishment of the BYMV subgroup. There was an oligonucleotide consensus sequence present in the 3' terminal non-coding region of all potyviruses examined. This consensus sequence divided the potyviruses into three groups whose significance is not clear.

摘要

为了研究马铃薯Y病毒属蚕豆黄花叶亚组病毒之间的关系，通过外壳蛋白的氨基酸序列和3'末端非编码区的核苷酸序列，对几种蚕豆黄花叶病毒（BYMV）和三叶草黄脉病毒（C1YVV）分离株进行了比较。序列比较表明，BYMV和C1YVV是不同的病毒，但彼此之间具有密切的亲缘关系（一种病毒的分离株之间的同源性为85-95%，但两种病毒之间的同源性为70-77%），这证明了蚕豆黄花叶病毒亚组的成立是合理的。在所检测的所有马铃薯Y病毒的3'末端非编码区中存在一个寡核苷酸共有序列。该共有序列将马铃薯Y病毒分为三组，其意义尚不清楚。
