Narcissus tip necrosis virus (NTNV) is a plant pathogenic virus of the family Tombusviridae, which infects plants of the genus Narcissus, the only known host. [1]
NTNV disease appears after flowering with large necrotic lesions which appear first near the leaf tips ('tip necrosis'). [1]
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).[ citation needed]
