Analysis of the triple gene block and coat protein sequences of two strains of Kalanchoë latent carlavirus.

A region of the Kalanchoë latent carlavirus (KLV) genome, containing the coding capacity for the triple gene block and the coat protein, was cloned and sequenced for two isolates, the one infecting Chenopodium quinoa systemically whereas the other infects C. quinoa locally. The sequence confirmed the classification of KLV as a carlavirus. There was the highest identity in the amino acid sequences to the carlaviruses potato rough dwarf virus, lily latent virus, lily symptomless virus, blueberry scorch virus and potato virus S. The aminoacid sequences of proteins of the two KLV isolates had an identity between 86% and 91%.
