Lily plants exhibiting virus-like symptoms of leaf yellowing, twisting and brownish necrotic spots were collected, and next-generation sequencing of small RNAs was conducted to identify the associated viruses. Cucumber mosaic virus, lily symptomless virus and a hitherto unrecorded potyvirus, tentatively named "lily yellow mosaic virus" (LYMV), were detected. The genomic RNA of LYMV was 9811 nt in length, encoding a large polyprotein of 3,124 amino acids with a predicted Mr of 353.3 kDa. BLAST analysis showed that LYMV shared a high degree of amino acid sequence identity with Thunberg fritillary mosaic virus (55%), bean yellow mosaic virus (52%), clover yellow vein virus (51%), leek yellow stripe virus (51%), and lily mottle virus (52%), and these viruses clustered together in a phylogenetic tree.
