“…In the 332 onion leaf samples collected during surveys and tested by DAS-ELISA, three viruses (OYDV, LYSV and SLV) were found infecting onions, with OYDV being the most widespread virus, Although OYDV is one of the most important viruses infecting garlic in some areas of Turkey [9,10] and elsewhere [11,14,18].…”

Amasya is the greatest onion producing area in Turkey. Onion fields from Amasya region were surveyed for virus diseases in 2009-2011 and tested for the presence of the most important onion viruses such as Onion yellow dwarf virus (OYDV), Iris yellow spot virus (IYSV), Leek yellow stripe virus (LYSV), Shallot latent virus (SLV) and Garlic common latent virus (GCLV). The presence of virus diseases and their identification was ascertained through symptom observation in the fields, sap transmission to hosts, and DAS-ELISA. Based on the ELSA results, 57 out of 332 samples (17.16 %) were infected with viruses. The results showed that the highest infection was caused by OYDV (12.33 %) followed by LYSV (3.60 %). Only 1.19 % of the samples were infected with SLV, but none of the samples were found to be infected for GCLV and IYSV.

“…The Potyvirus genus is the largest and economically most important group of plant viruses (Ward and Shukla, 1991). OYDV, an aphid-borne Potyvirus, is one of the major viral pathogens of onion and garlic (Mahmoud et al, 2008). Details of the occurrence of OYDV and LYSV have been described in Greece (Dovas et al, 2001), Brazil (Fajardo et al, 2001), Japan (Takaichi et al, 2001), and Italy (Dovas and Vovlas, 2003), but LYSV was not detected in tested onion and garlic samples in the current study.…”

Garlic is one of the most important Allium crops in Turkey. A survey for viruses infecting garlic (Allium sativum L.) was carried out in Samsun, Turkey. A total of 70 samples were collected and checked by biological and serological methods for the presence of Onion yellow dwarf virus (OYDV), Leek yellow stripe virus (LYSV), Garlic common latent virus (GarCLV), Shallot latent virus (SLV), and Iris yellow spot virus (IYSV) using virus-specific antiserum. OYDV was detected by double antibody sandwich-enzyme linked immunosorbent assay (DAS-ELISA) and bioassay in garlic (5.7%) samples collected from Samsun, Turkey.

“…Dilaporkan oleh Mahmoud et al (2008) bahwa OYDV yang menginfeksi umbi bawang putih memiliki partikel berupa batang lentur berukuran panjang 725-750 nm. OYDV juga telah dilaporkan keberadaannya di Rusia, Jepang, dan Korea.…”

“…Infeksi OYDV dapat menyebabkan penurunan produktivitas tanaman, baik secara kuantitatif (bobot umbi, tinggi tanaman, ukuran umbi) maupun kualitatif (bobot kering umbi) (Bagi et al 2012). Mahmoud et al (2008) melaporkan bahwa inokulasi mekanis OYDV pada tanaman C. amaranticolor menyebabkan munculnya gejala lesio nekrotik dan lesio lokal klorotik. Pada beberapa tanaman dari keluarga Alliaceae yang diinokulasi OYDV secara mekanis menunjukkan gejala yang cukup beragam.…”

ABSTRAKInfeksi virus di pertanaman bawang merah dapat menimbulkan gejala mosaik pada daun dan tanaman kerdil. Identitas virus penyebab penyakit perlu diketahui untuk menentukan pengelolaan penyakit yang tepat sasaran. Penelitian ini bertujuan mendeteksi virus terbawa umbi benih bawang merah. Deteksi virus dilakukan dengan uji tumbuh umbi, penularan mekanis, dan pengamatan morfologi partikel virus dengan mikroskop elektron. Bibit bergejala hasil uji tumbuh digunakan sebagai inokulum penularan mekanis. Penularan mekanis dilakukan pada tanaman bawang merah kultivar Biru Bantul, Chenopodium amaranticolor, dan Nicotiana tabacum. Inokulasi mekanis mengakibatkan munculnya gejala mosaik dan kerdil pada bawang merah, nekrosis lokal pada C. amaranticolor, dan tidak ada gejala pada N. tabacum. Hasil pengamatan mikroskop elektron menunjukkan 2 jenis partikel virus, yaitu filamen berukuran 650 nm dan filamen lentur berukuran 800 nm berturut-turut dari tanaman bergejala mosaik dan kerdil. Hal tersebut mengindikasikan ada 2 jenis virus yang terbawa benih bawang merah, yaitu diduga sebagai Shallot latent carlavirus (SLV) dan Onion yellow dwarf potyvirus (OYDV). Identitas virus perlu dikonfirmasi lebih lanjut berdasarkan analisis sikuen nukleotida dan proteinnya. Kata kunci: mikroskop elektron, penularan mekanis, uji tumbuh umbi ABTRACTVirus infection on shallots may cause mosaic of leaves and plant dwarf. It is very important to know the identity of the virus as a requirement in determining viral disease management strategy. The research is subjected to identify seed-transmitted viruses from shallot bulbs. Detection of virus from bulb was conducted by growing on test, followed by mechanical inoculation on shallot cultivar Biru Bantul, Chenopodium amaranticolor, and Nicotiana tabacum and morphological observation of virus particle by electron microscope. About 2 weeks after inoculation symptoms was observed, i.e. mosaic and dwarf on shallot cultivar Biru Bantul, local necrotic on C. amaranticolor, but symptomless on N. tabacum. Filamentous particles of 650 nm and 800 nm in length was observed under electron microscope from plants with mosaic and dwarfing symptom, respectively. This indicated the presence of 2 different seed-transmitted viruses on infected shallots. Two species of shallot viruses, i.e. Shallot latent carlavirus (SLV) and Onion yellow dwarf potyvirus (OYDV) was most likely the main seedborne viruses on shallot bulb. Identification based on nucleic acid and protein sequence analysis is necessary for further confirmation
