A novel citrus viroid was discovered in a non-symptomatic Lisbon lemon (Citrus x limon L. Burm.f.) tree in New South Wales, Australia. Bioindexing, molecular detection and characterization involving sequencing combined with in silico analysis for the identification of the viroid-RNA hallmark properties of transmissibility and autonomous replication as well as specific sequence and structural motifs suggest that this viroid is a member of a new species in the genus Apscaviroid, family Pospiviroidae, which we have tentatively named “citrus viroid VII” (CVd-VII).
