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.
测定了葫芦科蚜传黄化病毒中国分离株（CABYV-CHN）和一种暂称为甜瓜蚜传黄化病毒（MABYV）的新型马铃薯卷叶病毒属病毒的完整RNA基因组。CABYV-CHN的全基因组与法国CABYV分离株的核苷酸序列同一性为89.0%。相比之下，MABYV与CABYV及其他马铃薯卷叶病毒属病毒之间的核苷酸序列同一性在50.7%-74.2%之间，单个基因产物的氨基酸序列同一性在24.8%至82.9%之间。我们认为CABYV-CHN是CABYV的一个株系，而MABYV是马铃薯卷叶病毒属内一个暂定的不同种的成员。
