Abstract

The 3'-terminal 1221 nucleotides of a Zimbabwe isolate of cowpea aphid-borne mosaic potyvirus (CABMV) genome have been sequenced. The sequence comprises an open reading frame (ORF) of 990 nucleotides and a 3' non-coding-region of 231 nucleotides followed by a poly-A. The ORF has high similarity to NIb and coat proteins (CP) of potyviruses. A potential CP Q/S cleavage site was identified, yielding a CP of 30.5 kDa containing 275 amino acids. The CABMV sequence is closely related to that of South African passiflora virus (SAPV) which should therefore be regarded as a strain of CABMV.

摘要

已对豇豆蚜传花叶马铃薯Y病毒（CABMV）津巴布韦分离株基因组的3'端1221个核苷酸进行了测序。该序列包括一个990个核苷酸的开放阅读框（ORF）和一个231个核苷酸的3'非编码区，后面跟着一个聚腺苷酸。该ORF与马铃薯Y病毒属病毒的NIb和外壳蛋白（CP）具有高度相似性。鉴定出一个潜在的CP Q/S切割位点，产生一个包含275个氨基酸、分子量为30.5 kDa的CP。CABMV序列与南非西番莲病毒（SAPV）的序列密切相关，因此应将其视为CABMV的一个株系。
