Abstract A new distribution map is given for Melon necrotic spot virus (Tombusviridae: Carmovirus). The hosts include melon (Cucumis melo), cucumber (Cucumis sativus) and watermelon (Citrullus lanatus). Information is given on the geographical distribution in Europe (France, Greece, Crete, Italy, Sardinia, Netherlands, Norway, Spain, Canary islands, mainland Spain, Sweden, UK, England and Wales), Asia (China, Jiangsu, Iran, Israel, Japan, Hokkaido, Honshu, Kyushu, Shikoku, Korea Republic, Syria and Turkey), Africa (Tunisia), North America (Canada, Ontario, Mexico, USA, California) Central America and Caribbean (Guatemala, Honduras and Panama) and South America (Uruguay). The virus is transmitted by the fungal vector Olpidium bornovanus (syn. O. radicale) (Chytridiomycota: Olpidiaceae).

Necrotic Symptoms

We report a new strain of Melon necrotic spot virus (MNSV) that is unable to systemically infect Cucumis melo. A spherical virus (W-isolate), about 30 nm in diameter like a carmovirus, was isolated from watermelons with necrotic symptoms. The W-isolate had little serological similarity to MNSV, and it did not cause any symptoms in six melon cultivars susceptible to MNSV; however, the host range of the W-isolate was limited exclusively to cucurbitaceous plants, and transmission by O. bornovanus was confirmed. Its genomic structure was identical to that of MNSV, and its p89 protein and coat protein (CP) showed 81.6 to 83.2% and 74.1 to 75.1% identity to those of MNSV, respectively. Analysis of protoplast showed that the W-isolate replicated in melons at the single-cell level. Furthermore, chimeric clones carrying the CP of MNSV induced necrotic spots in melons. These results suggested that the absence of symptoms in melons was due to a lack of ability of the W-isolate to move from cell to cell. In view of these findings, we propose that the new isolate should be classified as a novel MNSV watermelon strain.
