چکیده

The nucleotide sequences of the coat protein genes and 3' non-coding regions of two aphid-transmissible isolates (G2 and G7) of soybean mosaic virus (SMV) were determined. The coat protein of the G2 isolate differs from that of the aphid non-transmissible N isolate by a single amino acid at position 12 (aspartic acid in N, glycine in G2 and G7). The G7 isolate differs from G2 and N at three and four amino acid residues, respectively. The nucleotide sequence similarity of the three isolates in the coat protein coding and 3' non-coding regions ranges from 93 to 100%, respectively. In contrast, watermelon mosaic virus 2 (WMV 2) is only 77% to 79% similar to the SMV isolates, suggesting that WMV 2 is a distinct virus and not an isolate of SMV as proposed previously.

Study on Genetic Diversity of Terminal Fragment Sequence of Isolated Persian Tobacco Mosaic Virus

Tobacco mosaic virus (TMV) is one of the devastating plant viruses in the world that infects more than 200 plant species. Movement protein plays a supportive role in the movement of other plant viruses, and viral coat protein is highly expressed in infected plants and affects replication and movements of TMV. In order to investigate genetic variation in the terminal fragment sequence in Iranian...

The Major Sources of Genetic Differentiation Among Apricot Latent Virus (ApLV) Isolates

Background and Aims: Apricot latent virus (ApLV) is a species within Foveavirus genus (Betaflexiviridae family, Tymovirales order). Phylogenetic analyses using different ORFs nucleotide sequences divided most ApLV isolates into two clusters. However, there is little data about the sources of genetic differentiation among ApLV isolates. Materials and Methods: Partial coat protein (CP) sequences...

Role of Pea Enation Mosaic Virus Coat Protein in the Host Plant and Aphid Vector

Understanding the molecular mechanisms involved in plant virus-vector interactions is essential for the development of effective control measures for aphid-vectored epidemic plant diseases. The coat proteins (CP) are the main component of the viral capsids, and they are implicated in practically every stage of the viral infection cycle. Pea enation mosaic virus 1 (PEMV1, Enamovirus, Luteovirida...

The use of 3' non-coding nucleotide sequences in the taxonomy of potyviruses: application to watermelon mosaic virus 2 and soybean mosaic virus-N.

The sequence of the 3' 1106 nucleotides of the watermelon mosaic virus 2 (WMV 2) genome has been determined. The sequence contains the complete coding region of the viral coat protein followed by a 3' untranslated sequence of 251 nucleotides. When these sequences were compared with the equivalent regions of the N strain of soybean mosaic virus (SMV-N), the coat protein coding regions were 82% h...
