“…At least seven RNA viruses (Chen et al 2008;Huang et al 1993) including CGMMV, CMV, Melon veinbanding mosaic virus, Melon yellow spot virus, PRSV-W, WSMoV and ZYMV, and one DNA virus, SLCPHV (Tsai et al 2007) have been reported to infect cucurbit plants in Taiwan. New virus-like symptoms of mosaic, leaf curl and puckering were observed on C. melo var.…”

Oriental melon plants, Cucumis melo var. makuwa cv. Silver Light, showing virus-induced symptoms of mosaic, leaf curl and puckering were observed in the fields of eastern Taiwan in 2007. A virus culture, designated as SL-1, isolated from the diseased melon was established in systemic host plants, Nicotiana benthamiana and oriental melon, by mechanical inoculation. SL-1 did not react to the antisera against common cucurbit-infecting RNA viruses. Viral DNAs extracted from the diseased plant were amplified with the degenerate primers for begomoviruses. The full-length genomic DNA-A and DNA-B of SL-1 were sequenced and found to be closest, with 97.7% and 90.6% nucleotide identity, respectively, to Tomato leaf curl New Delhi begomovirus (ToLCNDV) cucumber isolate from a group of cucurbit-infecting begomoviruses. The virus SL-1 was designated as ToLCNDV oriental melon isolate (ToLCNDV-OM). The pathogenicity of ToLCNDV-OM was confirmed by agroinfection. Progeny virus from the agroinfected N. benthamiana plants was able to infect oriental melon by mechanical inoculation and caused symptoms similar to the original diseased melon in the field. The ToLCNDV-OM also infected five other species of cucurbitaceous plants by mechanical inoculation. This is the first report of a new ToLCNDV isolate causing severe disease on oriental melon in Taiwan

“…MYSV was first detected on melon (Cucumis melo) in Shizuoka Prefecture in 1992 (Kato et al 2000), on cucumber (C. sativus) in Kochi Prefecture in 1995 (Takeuchi et al 2001), and on balsam pear (Momordica charantia) in Kochi Prefecture in 2007 (Takeuchi et al 2009). MYSV has become the prevalent virus of cucumber in the Kyusyu and Shikoku regions and has also been reported in Taiwan and Thailand (Chen et al 2008;Chiemsombat et al 2008). MYSV induces chlorotic spots, mosaic mottling, yellowing on leaves, and mosaic patches on fruits of melon, and sometimes causes mottling on fruits of cucumber.…”

Effect of temperature on symptom expression and viral spread of Melon yellow spot virus in resistant cucumber accessions

Melon yellow spot virus (MYSV), a member of the genus Tospovirus, is a devastating thrips-transmitted virus of cucurbits in Japan. Recently, we reported that cucumber accessions originating from South Asia, in particular Southeast Asia, had moderate resistance to MYSV. Here, we investigated the effect of three temperatures (20°C, 25°C, and 30°C) on symptom expression and viral spread of MYSV in plants of resistant cucumber accessions. No systemic infection developed in resistant cucumber plants after inoculation with melon isolate MYSV-S at low temperature (20°C); viral spread of MYSV-S and cucumber isolate MYSV-FuCu05P in inoculated cotyledons was suppressed. In contrast, higher incubation temperatures (25°C and 30°C) facilitated viral spread in inoculated cotyledons and systemic infection of MYSV-S. These data suggest that the resistance to MYSV of resistant cucumber accessions is temperature dependent.

“…The areas affected by MYSV are increasing, especially in the Kyushu, Shikoku, Tokai, and Kanto regions of Japan. In addition, MYSV has also been reported in Taiwan, Thailand, and China (Chen et al, 2008;Chiemsombat et al, 2008;Gu et al, 2012). The virus induces chlorotic spots, mosaic mottling, and yellowing on the leaves, and sometimes causes mottling on fruits.…”

Cucumber (Cucumis sativus L.) and melon (C. melo L.) are globally important crop species in the family cucurbit. However, pests and disease, including various viral diseases, affect cucumber and melon production in Japan. Choosing a resistant cultivar is one of the most effective methods for disease control. Many sources of viral resistance have been identified in cucurbits, and various resistant commercial cultivars have been bred. This review describes the present status of cucurbit breeding and sources of resistance to the four major viruses in Japan. Melon yellow spot virus (MYSV) and Cucurbit chlorotic yellows virus (CCYV) are devastating insecttransmitted viruses that were first reported in Japan. MYSV-resistant cucumber and CCYV-resistant melon were selected from germplasm collections. The resistance of cucumber accession 27028930 to MYSV is temperature dependent and intermediate; melon isolate (MYSV-S) inoculation resulted in no systemic infection of resistant cucumber plants at low temperature (20°C). The melon accession JP 138332 exhibits high resistance to CCYV. These accessions are considered promising sources for breeding resistant cultivars. Cucumber green mottle mosaic virus (CGMMV) and Melon necrotic spot virus (MNSV) are soil-borne viruses. The Korean melon accession 'Chang Bougi' is resistant to the SH isolate of CGMMV. The resistance of 'Chang Bougi' is controlled by two independent complementary recessive genes (cgmmv-1 and cgmmv-2), whereas resistance to MNSV is controlled by a single recessive gene (nsv) in melon. The nsv gene was introduced into commercial cultivars, and these cultivars have shown high resistance to MNSV. There is an increasing demand for new cultivars with resistance to additional viruses. To satisfy this demand and solve problems related to cucurbit viruses, core collections of each cucurbit crop are required for the identification of resistant germplasm, and marker-assisted selection will allow us to breed new cultivars rapidly and accurately.
