The hop stunt viroid (abbreviated HSVd, binomial name Hostuviroid impedihumuli) is a viroid species that infects the common hop plant,[1] citrus plants, grapevines, cucumber, and several Prunus species such as almond, apricot, plum, and peach.[2][3] It is asymptomatic or latent in most host plants, but in some hosts it can cause stunting and other symptoms. A study of HSVd-infected hops in the USA showed that the severity of yield reduction was highly dependent on the infected hop cultivar.[4]
HSVd is a member of the Pospiviroidae family and the Hostuviroid genus. There are various different sub-species of the hop stunt viroid.

[edit]The hop stunt viroid has a single-stranded RNA genome; the genome is 297 nucleotides long.[2]
