摘要： 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.
