Morphological, biological, serological, and molecular tests underpin the description of costus stripe mosaic virus (CoSMV) as a new member of the genus Potyvirus, family Potyviridae. Found affecting the native ornamental Costus spiralis in Brazil, the pathogen showed a severely restricted natural and experimental host range. Excluding the poly(A) tail, the CoSMV genome contains a large open reading frame (ORF) of 9,446 nucleotides that encodes a polyprotein with 3,046 amino acids, which is potentially cleaved into ten products, and a small ORF (77 amino acids) knows as PIPO.
