Narcissus tip necrosis virus

Narcissus tip necrosis virus (NTNV)
Virus classification
Group: Group IV ((+)ssRNA)
Family: Tombusviridae
Species: Narcissus tip necrosis virus

Narcissus tip necrosis virus (NTNV) is a plant pathogenic virus of the family Tombusviridae, which infects plants of the Narcissus genus, the only known host.[1]

Description

MTNV disease appears after flowering with large necrotic lesions which appear first near the leaf tips ('tip necrosis').[1]

Taxonomy

Narcissus tip necrosis virus was isolated in 1972.[1] At the 1987 ICTV meeting, that proposed the genus Carmovirus, Narcissus tip necrosis virus was listed as a 'tentative' member[2] but as of the 2013 release[3][4] it has still not been officially accepted. Note that the ICTV does not track tentative members,[5] so there are no further records in their databases, though still listed as tentative in the current Ninth Report (2009).
