Satyavativiridae Table of Contents

Family: Potyviridae

Genus: Phragmivirus

Distinguishing features

The genus includes two species, including isolates of common reed chlorotic stripe virus (CRCSV) and Spartina mottle virus (SpMV). The genome organization is similar to that of potyviruses and rymoviruses, encoding both the P3N-PIPO and a polyprotein from which 10 mature proteins are produced. Phragmiviruses encode a shorter P1 protein compared to those found in potyviriuses, but comparable to those of rymoviruses. 

Family: Potyviridae
