    Notes: Abstract Potyviral nuclear inclusion b protein (NIb), the RNA-dependent RNA polymerase, contains three highly conserved regions. Peptides corresponding to these regions were synthesised and used for immunisation. A panel of monoclonal antibodies was obtained. Most of the MAbs reacted with the peptides and a recombinant NIb of PVY in PTA-ELISA. Two of them specifically detected native NIb of potato A, potato V, potato Y, plum pox and turnip mosaic potyviruses in extracts of infected plants in Western blots. Time course experiments revealed that NIb protein can be first detected on the fifth day after infection.

    Notes: Abstract The 3026 nucleotides upstream of the 3′-polyadenylated tract of a mite transmitted virus fromHordeum murinum L. were cloned and sequenced, and portions of the sequence were expressed inEscherichia coli. Sequence comparisons with wheat streak mosaic virus (WSMV), Agropyron mosaic virus (AgMV) and Hordeum mosaic cirus (HoMV), three mite transmitted potyviruses, and potato virus Y (PVY), the type member of the genusPotyvirus, revealed that the virus is probably a potyvirus, but distinct from WSMV, AgMV, HoMV, and PVY. Serological tests further demonstrated these differences and that the virus is serologically related to another potyvirus, brome streak mosaic virus (BrSMV). We conclude that the virus should be named as the Hordeum isolate of BrSMV.
