Abstract
The complete genome sequence of a mandarin (Citrus reticulata) decline CTV isolate, Kpg3, of the Darjeeling hills of the Northeastern Himalayan region of India is reported for the first time. The complete Kpg3 genome has 19253 nt, and its nucleotide sequence identity ranged from 79% with the Florida CTV isolate T36 to 94% with the Israel isolate VT, whereas its identity to B165, the other Indian isolate, was 89%. Phylogenetic analysis indicated that the Kpg3 genome is closely related to isolate VT and distantly to T36 and B165. Recombination analysis indicated that Kpg3 is recombinant and originated through multiple recombination events in which parts of the genome were exchanged between divergent CTV sequences.
