利用新型简并聚合酶链式反应(RT-PCR)技术，鉴定了一株侵染越南黄麻(黄花科)的双节BegomoVirus。对这种病毒的分析表明，它与新大陆的新大陆病毒更相似，而不是来自东半球的病毒。这是基于缺乏AV2开放阅读框架，外壳蛋白中存在N-末端PWRLMAGT基序，以及DNA A和DNA B核苷酸及其推导的氨基酸序列的系统发育分析。有证据表明，CoYVV可能是该区域的土生土长的病毒，可能是旧大陆以前的新大陆海豚病毒种群的残留物。
A bipartite begomovirus infecting Jute mallow (Corchorus capsularis, Tilliaceae) in Vietnam was identified using novel degenerate PCR primers. Analysis of this virus, which was named Corchorus yellow vein virus (CoYVV), showed that it was more similar to New World begomoviruses than to viruses from the Old World. This was based on the absence of an AV2 open reading frame, the presence of an N-terminal PWRLMAGT motif in the coat protein and phylogenetic analysis of the DNA A and DNA B nucleotide and deduced amino acid sequences. Evidence is provided that CoYVV is probably indigenous to the region and may be the remnant of a previous population of New World begomoviruses in the Old World.
