Abstract
Faba bean necrotic yellows virus (FBNYV) has a multicomponent circular ssDNA genome. In addition to a previously described genome component (C1) coding for a replicase-associated protein (Rep), five further components (C2 to C6) have now been identified. Each of the six components is about 1 kb in size, contains one major open reading frame (ORF) in the virion sense with a TATA box and polyadenylation signal, and has a noncoding region containing a highly conserved sequence possibly forming s stem-loop structure. Similar to C1, C2 encodes another putative Rep of 33.1 kDa, which is closely related to the Rap of banana bunchy top virus (BBTV). Based on bacterial expression and immunoblot analysis, the ORF of C5 encodes the capsid protein (CP) with a deduced molecular mass of 19 kDa. The FBNYV CP shares the highest amino acid (aa) identity (56.2%) with that of subterranean clover stunt virus (SCSV]. The ORF of C4 potentially codes for a hydrophobic protein which appears to be structurally and functionally similar to the BBTV-C4 and SCSV-C1 proteins. No protein sequence similarities were found in databases for the C3 and C6 ORFs of FBNYV. FBNYV is clearly distinct from any known virus but is taxonomically related to BBTV and SCSV.
