Abstract The molecular characterization of isolates of citrus tristeza virus CTV from eight locations in Mexico was undertaken by analyzing five regions located at the opposite ends of the virus genome. Two regions have been previously used to study CTV variability coat protein and p23 while the other three correspond to other genomic segments p349-B p349-C and p13 . Our comparative nucleotide analyses included CTV sequences from different geographical origins already deposited in the GenBank databases. The largest nucleotide differences were located in two fragments located at the 5 end of the genome p349-B and p349-C . Phylogenetic analyses on those five regions showed that the degree of nucleotide divergence among strains tended to correlate with their pathogenicity. Two main groups were defined
