COMPARISON OF THE COAT PROTEIN OF GROUNDNUT ROSETTE ASSISTOR VIRUS WITH THOSE OF OTHER LUTEOVIRUSES

The coat protein gene of groundnut rosette assistor virus (GRAV) was c loned and sequenced. The deduced amino acid sequences of the coat prot ein and of another protein encoded in a different, overlapping, readin g frame resemble those of other luteoviruses. Four monoclonal antibodi es against GRAV, prepared using denatured coat protein as immunogen, a lso reacted with some other luteoviruses in ELISA. Nevertheless, they will be useful as reagents for the identification of GRAV infections i n groundnut.
