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 genus Potyvirus,[5] but never formally accepted.
