Nerine latent virus

Nerine latent virus (NeLV) is a plant pathogenic virus. It infects Nerine, Narcissus, Hippeastrum and Ismene plants.

Taxonomy

NeLV was first described in 1972.[1][2] In 2004 it was placed in the Carlavirus genus within the family Flexiviridae.[2][3] When that family was split in 2009, Carlavirus and NeLV were placed in the family Betaflexiviridae.

Narcissus symptomless virus

Narcissus symptomless virus was described as a separate virus taxon in 2006.[4] Subsequently, in 2016 it became apparent that the nucleotide sequence identities between Narcissus symptomless virus and the partial genome sequences of Nerine latent virus are 94-97% for coat protein and replicase, well above the threshold 72% set for speciation of flexiviruses. Consequently, these two viruses can be considered to be the same taxon, and since NeLV has priority, Narcissus symptomless virus should be reduced to a synonym.[2][5]

gollark: oO0 - the devil's triplet.
gollark: I have one and only one 2G.
