Citrus tristeza virus (CTV) displays a wide range of serological diversity. Strains have been reported from various countries that do not react with some of the CTV-specific monoclonal antibodies (BAb). We investigated the molecular basis for the emergence of these serotypes of CTV. While CTV-specific MAb MCA 13 reacts predominantly with severe strains that cause quick decline and/or stem pitting, 3DF1 is a broad spectrum MAb that reacts with a majority of the CTV strains. To map the antigenic determinants recognized by these MAbs, capsid protein (CP) genes of several serologically and biologically diverse strains from differnt parts of the world were cloned and sequenced. Sequence comparisons showed that phenylalanine (Phe) at position 124 of the CP was conserved among all the MCA13-reactive strains. |
