Abstract:
Ten cDNA clones, representing the satellite-like RNA-3 associated with five different isolates of groundnut rosette virus, were prepared and sequenced. The sequences are at least 87% identical, but differences associated both with symptom differences and with geographical origin were found. The sequences contain up to five potential open reading frames (ORFs), of which three are in the strand that is most abundant in infected plants and two are in the complementary strand. Only one of these ORFs is present in all 10 sequences. Neither the sequence of RNA-3 nor that of its potential translation products had significant similarities to sequences in the databases.
