Abstract: The cytoplasmic inclusion (CI) gene of a Singapore isolate of zucchini yellow mosaic virus (ZYMV-S) was sequenced and compared with CI of 14 other potyviruses. In addition to the consensus sequence GAVGSGKST of nucleotide binding motif (NTBM) which is implicated as a membrane-binding component of the RNA helicase complex, five other conserved motifs were found. Phylogenetic trees were constructed from sequence data for the CI and the coat protein. Similar branching patterns obtained from both CI and coat prote… Show more

DNA sequences for the coat protein (CP) and part of the cytoplasmic inclusion (CI) protein genes after reverse transcriptase-polymerase chain reaction (RT-PCR) were reported for the first time for isolates of zucchini yellow mosaic virus (ZYMV) from Austria, Germany, Italy and Slovenia. Comparison of the DNA sequences of 30 isolates from different geographical regions worldwide revealed highest similarities of the Austrian isolates to those from Slovenia and Hungary. Isolates from Germany and Italy were only distantly related and clustered with isolates from other parts of the world. Our results indicate that a specific isolate can spread rapidly to geographically adjacent areas but may not be directly related to isolates found in other neighboring countries.

The variability of North American and Asian strains and isolates of Soybean mosaic virus was investigated. First, polymerase chain reaction (PCR) products representing the coat protein (CP)-coding regions of 38 SMVs were analyzed for restriction fragment length polymorphisms (RFLP). Second, the nucleotide and predicted amino acid sequence variability of the P1-coding region of 18 SMVs and the helper component/protease (HC/Pro) and CP-coding regions of 25 SMVs were assessed. The CP nucleotide and predicted amino acid sequences were the most similar and predicted phylogenetic relationships similar to those obtained from RFLP analysis. Neither RFLP nor sequence analyses of the CP-coding regions grouped the SMVs by geographical origin. The P1 and HC/Pro sequences were more variable and separated the North American and Asian SMV isolates into two groups similar to previously reported differences in pathogenic diversity of the two sets of SMV isolates. The P1 region was the most informative of the three regions analyzed. To assess the biological relevance of the sequence differences in the HC/Pro and CP coding regions, the transmissibility of 14 SMV isolates by Aphis glycines was tested. All field isolates of SMV were transmitted efficiently by A. glycines, but the laboratory isolates analyzed were transmitted poorly. The amino acid sequences from most, but not all, of the poorly transmitted isolates contained mutations in the aphid transmission-associated DAG and/or KLSC amino acid sequence motifs of CP and HC/Pro, respectively.

Vanilla mosaic virus isolates from French Polynesia and the Cook Islands are Dasheen mosaic virus strains that exclusively infect vanilla

Sequence was determined for the coat protein (CP) gene and 3' non-translated region (3'NTR) of two vanilla mosaic virus (VanMV) isolates from Vanilla tahitensis, respectively from the Cook Islands (VanMV-CI) and French Polynesia (VanMV-FP). Both viruses displayed distinctive features in the N-terminal region of their CPs; for VanMV-CI, a 16-amino-acid deletion including the aphid transmission-related DAG motif, and for VanMV-FP, a stretch of GTN repeats that putatively belongs to the class of natively unfolded proteins. VanMV-FP CP also has a novel DVG motif in place of the DAG motif, and an uncommon Q//V protease cleavage site. The sequences were compared to a range of Dasheen mosaic virus (DsMV) strains and to potyviruses infecting orchids. Identity was low to DsMV strains across the entire CP coding region and across the 3'NTR, but high across the CP core and the CI-6K2-NIa region. In accordance with current ICTV criteria for species demarcation within the family Potyviridae, VanMV-CI and VanMV-FP are strains of DsMV that exclusively infect vanilla.
