Abstract
The nucleotide sequence diversity of the CPm gene from 28 field isolates of Citrus tristeza virus CTV was assessed by SSCP and sequence analyses These isolates showed two major shared haplotypes which differed in distribution A1 was the major haplotype in 23 isolates from different geographic regions whereas R1 was found in isolates from a discrete region Phylogenetic reconstruction clustered A1 within an independent group while R1 was grouped with mild isolates T30 from Florida and T385 from Spain Some isolates contained several minor haplotypes which were very similar to and associated with the major haplotypeO OliverosGaray was a recipient of a Colciencias PhD scholarship The authors would like to thank Colciencias for partially financing this research project code 110112652 and also Universidad Nacional de Colombia project codes 20201006310 and 8001002
