Abstract
A tospovirus that infected peanut was found in central Taiwan.
The virus induces chlorotic fan-shaped lesions with concentric rings along the main veins of the leaflets.
Lesions later turn brown and necrotic.
The virus was mechanically transmitted to Chenopodium quinoa, Nicotiana benthamiana, N. edwardsonii, N. rustica, N. tabacum cv.
White Burley, and Datura stramonium, where it induced chlorotic or necrotic lesions on the inoculated leaves.
Thin sections ofdiseased leaf tissue from host plants contained spherical to oval particles characteristic of a tospovirus.
In screenhouse tests, Scirtothrips dorsalis transmitted the virus in a persistent manner; whereas, Frankliniella williamsi and Thrips palmifailed to do so.
The peanut virus, tentatively referred to as peanut chlorotic fan-spot virus (PCFV), showed no serological relationship with tomato spotted wilt virus, watermelon silver mottle virus, or impatiens necrotic spot virus by enzyme-linked immunosorbent assay (ELISA) tests using antisera specificfor these tospoviruses.
Although there are some similarities in host reaction between PCFVand the virus that causes peanut yellow spot in India, their identity remains to be determined.
