Ficus pumila is an edible garden plant with significant medicinal value. In this study, we identified a novel maculavirus associated with mosaic and chlorotic spot symptoms on F. pumila leaves in Yunnan Province, China, and the genome sequence of the virus, which was tentatively named "Ficus pumila-associated virus" (FPaV), was determined. The FPaV genome consists of a single molecule of positive-sense ssRNA that is 6,664 nucleotides in length and has a high cytidine content of 40.8%. The genome exhibits a tymovirus-like organization, encoding a movement protein (MP), a replicase polyprotein, and a coat protein (CP). Phylogenetic analysis showed FPaV to be most closely related to grapevine fleck virus (GFkV), with 67.86% nucleotide sequence identity across the complete genome.
薜荔是一种具有重要药用价值的可食用园林植物。在本研究中，我们在中国云南省的薜荔叶片上鉴定出一种与花叶和褪绿斑点症状相关的新型黄斑病毒，并测定了该病毒的基因组序列，暂命名为“薜荔相关病毒”（FPaV）。FPaV基因组由一个长度为6664个核苷酸的单分子正义ssRNA组成，胞嘧啶含量高，为40.8%。该基因组呈现出类番茄病毒的结构组织，编码一个运动蛋白（MP）、一个复制酶多聚蛋白和一个外壳蛋白（CP）。系统发育分析表明，FPaV与葡萄斑点病毒（GFkV）关系最为密切，全基因组核苷酸序列同一性为67.86%。
