Abstrakt: A novel macluravirus, tentatively named "tsaoko stripe mosaic virus" (TkSMV), was identified in Amomum tsaoko through high-throughput sequencing. The complete genome sequence of TkSMV was determined using RT-PCR and RACE. The genome sequence consists of 8218 nucleotides, excluding the poly(A) tail, and contains a large open reading frame encoding a polyprotein of 2625 amino acids with a molecular weight of approximately 297.13 kDa. TkSMV is most closely related to Alpinia oxyphylla mosaic virus, sharing 71.5% nucleotide and 75.9% amino acid sequence identity. These values are below the species demarcation threshold for the family Potyviridae. These results suggest that TkSMV should be considered a distinct member of the genus Macluravirus.
