| Abstrak/Abstract |
Among many cucurbits grown around Yogyakarta-Indonesia as vegetables, angled loofah (Luffa acutangula L.) occupies a minor portion of cultivated area for continuous supply to the local market. During 2-year surveys of viral diseases conducted in Yogyakarta, Indonesia from 2000 to 2001, many angled loofah plants showed mosaic symptom on leaf and fruit malformation. A virus was isolated from symptomatic leaves of angled loofah and shown to be a member of genus Tobamovirus based upon viral morphology observed under electron microscopy. Serological analysis revealed that the virus was related to Kyuri green mottle mosaic virus (KGMMV). Comparison of its coat protein gene and protein sequences with that of KGMMV-YM, KGMMV-C, and KGMMV-Y indicated that the virus was similar to previously reported KGMMV. By mechanical inoculation, the virus infected 3 families including 15 species, showing mosaic in some cucurbit plants and necrotic local lesions in Chenopodium amaranticolor and C. quinoa. This virus, however, could not infect Datura stramonium, Petunia hybrida, and Nicotiana glutinosa. Since no KGMMV on angled loofah have been reported in Indonesia, this is the first report and followed by the report of KGMMV occurrence except on melon (Cucumis melo ?.) in Indonesia. |
