Characterization of Potyviruses from Tulip and Lily which Cause Flower-Breaking Dekker, Elise L. and Derks, Antonius F. L. M. and Asjes, Cees J. and Lemmers, Miriam E. C. and Bol, John F. and Langeveld, Simon A.,, 74, 881-887 (1993), doi = https://doi.org/10.1099/0022-1317-74-5-881, publicationName = Microbiology Society, issn = 0022-1317, abstract= Five viruses causing colour-breaking of tulip flowers were isolated from tulips and lilies. Tulip-breaking virus (TBV), tulip top-breaking virus (TTBV), tulip band-breaking virus, Rembrandt tulip-breaking virus and lily mottle virus were all characterized as potyviruses by serology and potyvirus-specific PCR. Sequence analysis of amplified DNA fragments spanning a conserved area of the coat protein cistron of potyviruses was performed in order to classify the isolates as distinct viruses or strains. It appears that all tulip-breaking viruses are distinct viruses and TTBV was found to be strain-related to turnip mosaic virus., language=, type=
