Zusammenfassung: | The nucleotide sequences of the small intergenic region (SIR) and the gene encoding the coat protein of 12 maize streak virus (MSV) isolates from different geographic locations have been determined. These have been used to assess the variability of the virus and to construct evolutionary dendrograms. For the viruses analyzed, the maximum levels of sequence divergence were found to be 10.9% and 2.0% at the nucleotide and amino acid levels, respectively. A genetically distinct strain of MSV was collected from islands in the Indian ocean. The significance of these findings for detection of the virus in epidemiological studies and breeding of resistant plant varieties is discussed. |
