Tulip Virus Colour

Tulip breaking virus[a] is one of five plant viruses of the family Potyviridae that cause color-breaking of tulip flowers. These viruses infect plants in only two genera of the family Liliaceae: tulips (Tulipa) and lilies (Lilium). Biology Several viruses affecting tulips are spread by many species of aphids.

Viruses overwinter in infected bulbs. White and yellow cultivars do not exhibit obvious symptoms and therefore may increase the risk that the disease will spread to other tulips. Foliar symptoms are rare but may occur on some varieties.

Flower petals show streaks, stripes, feathering, or flames of different colors. TULIP BREAKING OR MOSAIC Tulip "breaking" is an old term that refers to an unusual mosaic pattern of petal colors. Typically, dark colors appear on a lighter colored background, with the patterns of the darker colors being irregularly broken into stripes, flecks, or featherings (Figure 1).

The condition is caused by one or more viruses, and because it is not genetically induced, the. In the present study, we aimed to determine the diversity of potyviruses present in Hungarian tulip plants showing typical color breaking syndrome. We also analyzed the taxonomic relationships between tulip infecting potyviruses and incidence of recombination in the evolution of tulip infecting potyviruses.

Tulip breaking virus (TBV) is defined as a plant virus in the Potyviridae family that causes color loss in tulip flowers and primarily infects tulips (Tulipa) and lilies (Lilium). It is associated with the phenomenon of ornamental flower breaking, which historically influenced the value of tulips.

What are tulip viruses? There are at least 12 viruses that infect tulips, causing a range of symptoms, which are seen when the tulips have grown leaves in spring and early summer. The six most important are: Tulip breaking virus (TBV) Arabis mosaic virus (ArMV) Tobacco rattle virus (TRV) Lily symptomless virus (LSV) Tobacco necrosis virus (TNV) Cucumber mosaic virus (CMV) For more on how these. The Dutch believed the tulip breaking virus could be transferred to other bulbs and also had the potential to weaken and change entire crops and varieties.

The viral discovery resulted in a ban on broken tulips in The Netherlands, whose economy in part relies on producing high-quality, uniform bulbs that result in a specific flower. A virus in tulips, the TBV, or tulip-breaking virus, caused amazing color patterns in tulips but also weakened the bulb. After many generations the bulbs became weaker, until they would be too weak to flower and the genetic line died off.

Tulips are originally from central Asia, and Turkey introduced tulips to the Netherlands in the 17th century. Causes flower 'breaking' in red and purple varieties of tulip species and their hybrids; it affects the amount of anthocyanin in the vacuoles of epidermal cells in the petals (Dufrénoy, 1931), resulting in different types of colour.
