Wheat streak mosaic virus

Genome organization; box represents the polyprotein open reading frame with vertical lines demarcating sites of cleavage by viral proteinases. Predicted mature proteins are labelled by analogy to other potyviruses: P1 - P1 protein, HC-Pro - helper component and proteinase (note that it is not known whether HC-Pro of WSMV is involved in transmission of the virus by mites), P3 - P3 protein, 6K1 and 6K2 - 6 kDa proteins, CI - cytoplasmic inclusion protein, NIa - comprised of a 5' genome-linked protein (VPg) and proteinase (Pro) domains, NIb - replicase, and CP - coat protein.
