Nucleotide sequence comparison of the 3' terminal region of the genome of pepper vein mottle virus isolates from Tunisia and Ivory Coast.
Three Tunisian PVMV isolates identified in pepper and tomato fields and one isolate from Ivory Coast were submitted to biological and molecular analysis. Phenotypically, Tunisian isolates induced mild symptoms while the Ivory Coast one is more aggressive on tobacco. As no PVMV sequence data are available, detailed sequence comparisons of coat protein gene (CP) were made. No nucleotide or amino acid changes in this region could be related to the pathogenicity of the isolates analysed. With the aim to increase our molecular understanding of the biological properties, we have sequenced the 3'-non translated region (3'NTR). Results suggest that this region of the RNA genome may be involved in the modulation of disease symptoms.
