Narcissus white streak virus

Narcissus white streak virus (NWSV)
Virus classification
Group: Group IV ((+)ssRNA)
Order: Unassigned
Family: Potyviridae
Species: Narcissus white streak virus

''Narcissus white streak virus (NWSV) is a plant pathogen of the family Potyviridae which infects plants of the genus Narcissus, and is transmitted by aphids.[1] It is among the commonest and most serious of the viral infections that infect narcissi,[2][3] but appears to be confined to N. tazetta.[4]

Description

This virus causes narrow greenish purple streaks that turn white to yellow, on the leaves and flower stalk after flowering, and premature senescence, which reduces bulb size and yields.[1]

Taxonomy

Despite its importance, there is relatively little phylogenetic information on NWSV and its taxonomy remains unresolved. It has been proposed as a tentative member of the Potyvirus genus,[5] but never formally accepted.
