Also known as the tulip break virus, lily streak virus, lily mosaic virus, or simply TBV, tulip breaking virus is most famous for its dramatic effects on the color of the tulip perianth, an effect highly sought after during the 17th-century Dutch "tulip mania". [3] Tulip breaking virus is a potyvirus. [4]
She concluded that the infectious agent was a virus as the filtrate of an infected bulb did not cause "breaking", and that the virus was probably spread by aphids. [3] Tulip enthusiasts who wanted "true colours" were pleased as the research showed that "breaking" could be prevented by stopping infection of the bulbs (for example, by aphids).
Variegation produced by the tulip breaking virus. Botrytis tulipae is a major fungal disease affecting tulips, causing cell death and eventually the rotting of the plant. [26] Other pathogens include anthracnose, bacterial soft rot, blight caused by Sclerotium rolfsii, bulb nematodes, other rots including blue molds, black molds and mushy rot. [27]
Resistant to tulip breaking virus, it has been crossed into garden tulips (Tulipa × gesneriana). [11] They naturalize easily and can come back year after year in the garden. They are well suited to mixed borders and can also be used in bedding displays. [5] They can grow in any garden soil but prefer sites in full sun.
The Vietnamese Wikipedia initially went online in November 2002, with a front page and an article about the Internet Society.The project received little attention and did not begin to receive significant contributions until it was "restarted" in October 2003 [3] and the newer, Unicode-capable MediaWiki software was installed soon after.

An arenavirus is a bi- or trisegmented ambisense RNA virus that is a member of the family Arenaviridae. [1] [2] These viruses infect rodents and occasionally humans.A class of novel, highly divergent arenaviruses, properly known as reptarenaviruses, have also been discovered which infect snakes to produce inclusion body disease, mostly in boa constrictors.
Replication follows the ssDNA rolling circle model. DNA-templated transcription is the method of transcription. The virus exits the host cell by nuclear pore export, and tubule-guided viral movement. Legume plants serve as the natural host. The virus is transmitted via a vector (the virus does not replicate in this). Transmission routes are vector.
