The complete nucleotide sequence of the genomic RNA of the potyvirus potato virus Y strain N (PVYn) was obtained from cloned cDNAs. This sequence is 9704 nucleotides long and can encode a polyprotein of 3063 amino acids. The positions of the cleavage sites at the N terminus of the capsid and cytoplasmic inclusion proteins have been determined. Other(More)
A PCR diagnostic test for detection of Ralstonia solanacearum at the infraspecific level was developed, based on polymorphisms within the 16S rRNA gene sequence. Partial sequences of this gene were determined for three French isolates which showed the characteristics of R. solanacearum subdivision 2a described by Taghavi et al. (1996). Oligonucleotide(More)
Cauliflower mosaic virus (CaMV) gene I encodes a protein (P1) that has been implicated in the control of virus movement in infected plants. To assist in the characterization of the mechanism of action of P1, gene I has been expressed efficiently inSpodoptera frugiperda (Sf) cells using recombinant baculovirus. Control of the expression of CaMV gene I by the(More)
