测定了瓜类蚜传黄化病毒（CABYV-CHN）和甜瓜蚜传黄化病毒（MABYV）的RNA全基因组。CABYV-CHN的全基因组核苷酸序列与法国CABYV分离物的核苷酸序列同源性为89.0%。相比之下，MABYV和CABYV与其他polerovirus之间的核苷酸序列同一性在50.7- 74.2%的范围内，单个基因产物的氨基酸序列同一性在24.8 - 82.9%的范围内。我们认为CABYV-CHN是CABYV的一个株系，MABYV是Polerovirus属内一个暂定的不同种的成员。
The complete RNA genomes of a Chinese isolate of cucurbit aphid-borne yellows virus (CABYV-CHN) and a new polerovirus tentatively referred to as melon aphid-borne yellows virus (MABYV) were determined. The entire genome of CABYV-CHN shared 89.0% nucleotide sequence identity with the French CABYV isolate. In contrast, nucleotide sequence identities between MABYV and CABYV and other poleroviruses were in the range of 50.7-74.2%, with amino acid sequence identities ranging from 24.8 to 82.9% for individual gene products. We propose that CABYV-CHN is a strain of CABYV and that MABYV is a member of a tentative distinct species within the genus Polerovirus.
