Biological and molecular characterization of a highly divergent Johnsongrass mosaic virus isolate from Pennisetum purpureum
Archives of Virology 161 (7), 1981-1986
Abstract: The complete genome sequence (9,865 nucleotides) of a highly divergent johnsongrass mosaic virus isolate (JGMV-CNPGL) was determined using Illumina sequencing. This isolate infected 10 genotypes of gramineous plants including maize. A comparative analysis of the complete genome showed 80 % nucleotide (nt) sequence identity (86 % amino acid (aa) sequence identity) to a johnsongrass mosaic virus isolate from Australia. The coat protein (CP) identity values, however, were lower than those for the whole genome (78 % and 80 % for nt and aa, respectively) and were close to the species demarcation values (77 % nt and 80 % aa). Unexpectedly, the amino-terminal portion of CP of JGMV-CNPGL showed only 38 % sequence identity to other JGMV isolates. The biological implications of this sequence divergence remain to be elucidated.
