Abstract
In this report, we present the first description of nine complete genome sequences of a new strain of chayote yellow mosaic virus (ChaYMV, genus Begomovirus, family Geminiviridae), provisionally named Côte d’Ivoire (ChaYMV-CI), isolated from bitter melon (Momordica charantia) leaf samples showing yellow mosaic symptoms collected in the region of Abidjan in Côte d’Ivoire in 2013 and 2019. The nucleotide sequences of ChaYMV-CI DNA-A-like genome share the highest nucleotide sequence identities (91.8–92.5%) with those of ChaYMV isolates from Benin and Cameroon. Phylogenetic analysis confirmed the segregation of ChaYMV isolates into two distinct clades and their affiliation to Old World monopartite begomoviruses. The discovery of a new strain of ChaYMV in West Africa, at the limit of the taxonomic demarcation threshold for begomoviruses (91%), call for further investigations into the molecular diversity, geographical distribution and host range of ChaYMV in Western Africa.
在本报告中,我们首次描述了2013年和2019年在科特迪瓦阿比让地区采集的表现出黄色马赛克症状的苦瓜(Momordica charantia)叶片样本中分离出的一种新的chayote黄色马赛克病毒株(ChaYMV,Begomovirus属,Geminiviridae科)的9个完整基因组序列,暂时命名为科特迪瓦(ChaYMV-CI)。ChaYMV CI DNA-A样基因组的核苷酸序列与来自贝宁和喀麦隆的ChaYMV分离株的核苷酸序列具有最高的核苷酸序列同源性(91.8–92.5%)。系统发育分析证实了ChaYMV分离株被分离成两个不同的分支,并与旧大陆的单体秋海棠病毒有亲缘关系。在西非发现了一种新的ChaYMV菌株,该菌株达到了秋海棠病毒的分类分界阈值(91%),这需要进一步研究ChaYMV在西非的分子多样性、地理分布和宿主范围。
