Tulip breaking virus
The Tulip breaking virus is one of five plant viruses of the family Potyviridae that cause color-breaking of tulip flowers. These viruses infect only two genera of plants: Tulipa (tulips) and Lilium (lilies), (family Liliaceae). Tulip-breaking virus (TBV), Tulip top-breaking virus (TTBV), Tulip bandbreaking virus (TBBV), Rembrandt tulip-breaking virus (ReTBV) and Lily mottle virus (LMoV) have all been identified as potyviruses by serology and potyvirus-specific polymerase chain reaction (PCR). In addition, sequence analysis of amplified DNA fragments has classified them all as distinct viruses or strains; recently TTBV has been found to be strain-related to turnip mosaic virus.
