Potyvirids are viruses with a ssRNA genome packaged in long filamentous particles. While members of the genus&nbsp;<em>Bymovirus<\/em>&nbsp;have bipartite genomes, members of the remaining genera have monopartite genomes. All viruses in the family have a genome-linked protein (VPg) present at the 5\u2019 terminus of the genome, and all but celery latent virus (genus&nbsp;<em>Celavirus<\/em>) have a polyadenylated tail at the 3\u2019 end. The members of the 12 genera are differentiated by genomic sequence identity, various functional motifs, and biological factors such as the type of the transmission vector and host range. Demarcation criteria for a new genus include\u2009&lt;\u200946% nucleotide sequence identity to potyvirids of other genera. Here, we report the new genus&nbsp;<em>Phragmivirus<\/em>&nbsp;within the family&nbsp;<em>Potyviridae<\/em>, which has been accepted by the International Committee on Taxonomy of Viruses, becoming the 13th genus in the family. The genus&nbsp;<em>Phragmivirus<\/em>&nbsp;is represented by two virus species (<em>Phragmivirus phragmii<\/em>&nbsp;and&nbsp;<em>Phragmivirus spartinae<\/em>). Complete genome sequences are available for both members, namely, common reed chlorotic stripe virus (CRCSV) and Spartina mottle virus (SpMV), respectively. The new genus name is derived from the botanical name of the host of CRCSV,&nbsp;<em>Phragmites australis.<\/em>&nbsp;The genome sequences of CRCSV and SpMV isolates resemble those of members of the genus&nbsp;<em>Potyvirus<\/em>&nbsp;but lack typical conserved aphid-transmission motifs.<\/p>\n\n\n\n<p>Read more at: <a
