Figure 1 Negative contrast electron micrograph of particles of Parsnip yellow fleck virus (PYFV) stained in 1% uranyl acetate. The bar represents 100 nm.
Figure 2 Genome structures of Parsnip yellow fleck virus (PYFV) and Rice tungro spherical virus (RTSV). The boxes represent the polyproteins encoded by the large ORFs. The vertical solid lines show where cleavages are known to occur in the polyproteins and the dashed lines show where cleavages are presumed to occur. The approximate positions of NTP-binding (filled square), protease (filled diamond) and polymerase (filled circle) are shown.
