“…P1AMV has been shown to be serologically unrelated to PVX (Minskaya et al, 1977). The host range, virion length and M r of the coat protein of P1AMV are different from those of three other Plantago potexviruses described previously (Rowhani & Peterson, 1980;Hammond & Hull, 1981;Gracia et al, 1983).…”

The complete nucleotide sequence of Plantago asiatiea mosaic virus (P1AMV) genomic RNA has been determined. The 6128 nucleotide sequence contains five open reading frames (ORFs) coding for proteins of Mr 156K (ORF1), 25K (ORF2), 12K (ORF3), 13K (ORF4) and 22K (ORF5). The sequences of these PIAMV proteins exhibit strong homology to the proteins of the other potexviruses. Phylogenetic trees based on the multiple sequence alignments of three conserved domains in ORF1 product and capsid protein reveal a close relationship of P1AMV to papaya mosaic virus and clover yellow mosaic virus. The PIAMV genomic RNA and a major subgenomic RNA (sgRNA) of 0.9 kb have been detected in infected leaves by Northern blot hybridization. The latter sgRNA is the messenger for virus capsid protein and its 5' terminus has been located 23 nucleotides upstream of the initiator codon of the coat protein gene. The P1AMV virion RNA and RNA transcript resembling the 0-9 kb sgRNA have been translated in vitro giving rise to a single major 170K product and a major 22K product, respectively.

“…This latter virus was not seed transmitted and the name dandelion carlavirus has been proposed. In Argentina, a potexvirus caused severe mosaic and leaf malformations on T. officinale plants and was provisionally named Argentine plantago virus (AplaV) (Gracia et al 1983). Taraxacum officinale is also a host for a yellowing disease caused by beet pseudo yellows virus (BPYV) (Duffus 1965;Soria et al 1991).…”

is a perennial weed occurring in parks, gardens, pastures, orchards, roadsides, vegetable gardens, agricultural crops and horticultural crops. A common weed worldwide, it was originally introduced from Eurasia and now occurs in every province of Canada. It is an aesthetic problem during flowering and seed production, interrupting turfgrass uniformity and density; it reduces yields of agricultural crops; it causes slower drying of hay; its pollen is allergenic; and it acts as an alternative host for several pests and diseases. A number of herbicides are available for its control. Mechanical removal of T. officinale plants has limited success, due to the regenerative capacity of the long taproot. Insects, fungi, sheep and geese have been considered as biological control agents for dandelion.

The coat proteins of tymo‐, tombus‐, como‐, nepo‐, tobamo‐, potex‐, carla‐ and potyviruses were subjected to sodium dodecylsulphate (SDS)‐polyacrylamide gel electrophoresis, electro‐blotted onto nitrocellular membranes and reacted with homologous and heterologous antìsera to intact plant viruses. Immune complexes were detected after reaction with alkaline phosphatase‐labelled goat anti‐rabbit antibodies. SDS coat proteins of comoviruses reacted only with antisera which were homologous for their intact particles. In all other groups, however, a rather broad range of serological relationships was detected. With a number of viruses, serological relations to other members of the same group were demonstrated for the first time. SDS coat proteins of maclura mosaic virus, a possible potyvirus, and of beet necrotic yellow vein virus, a possible tobamovirus, did not react with antisera to definitive members of the respective groups. Several unexpected reactivities of SDS coat proteins of viruses from one group with antisera to viruses in other groups were, however, also observed. This indicated that electro‐blot immunoassay, like other serological methods, cannot be used reliably to assign a virus to a certain group. The SDS coat proteins of several tombusviruses were able to mimic serological reactions by a direct binding of enzymelabelled antibodies which occurred also without serum treatment.
