Abstract
Citrus tristeza virus (CTV) culture, collected from a fifteen-year-old wilted and declined mosambi sweet orange [Citrus sinensis (L) Osb] plant, was maintained under green house into acid lime [C. aurantifolia Swing] and mosambi seedlings. It gave positive reaction in ELISA, both with CTV specific polyclonal antibodies (G604) and monoclonal antibody MCA13, which specifically detects severe CTV strains. Coat protein gene (CPG) of the virus was amplified by RT PCR using CPG specific primers yielding an amplicon of 672 bp. Sequence analysis of the CPG amplicon showed 97% nucleotide sequence homology with Chinese isolate CTV-0002 (Acc. No. AJ518841) and isolate S4 (Acc. No. EF063109). In phylogenetic analysis, the present CTV isolate was displayed in different clade than other reported Indian CTV isolates, but it shared a separate clade with isolates from China, Israel, Jordan and New Zealand.
