Doğu Akdeniz Bölgesi’nde Karpuz Yetiştirilen Alanlarda Karpuz Mozayik Virüsü (WMV-2)’nün Biyolojik, Serolojik ve Moleküler Olarak Belirlenmesi

Öz

Çalışma, Adana, Mersin ve Osmaniye illerinde karpuz yetiştirilen alanlarda WMV-2’ nin serolojik, biyolojik ve moleküler yöntemler kullanılarak saptanması ve tanılanması amacı ile 2012 yılı ilkbahar ve yaz aylarında yürütülmüştür. Araziden toplanan ve virüslü olduğundan şüphenilen bitki örnekleri öncelikle ELISA yöntemi ile testlendi ve toplanan örneklerde WMV-2 ile bulaşıklık oranı % 46.7 olarak hesaplanmıştır. Mekanik inokulasyon yöntemi ile WMV-2 bulaştırılan kabak (Cucurbita pepo L.), kavun (Cucumis melo L.), hıyar (Cucumis sativus L.) ve karpuz (Citrillus lanatus (Thunb.) Matsum. & Nakai) bitkilerinin yapraklarında, mozayik, deformasyon, kabarcıklaşma ve damar bantlaşması, akkazayağı (C. quinoa Willd., C. amaranticolor Coste and Reynier) ve hanım düğmesi (G. globosa L.) bitkilerinin yapraklarında ise, klorotik lokal lezyonlar gözlenmiştir. Tütün (N. tabacum L. Nicotiana benthamiana L. N. glutinosa L. ve N. rustica L.) bitkilerinin yapraklarında ise, herhangi bir simptom ortaya çıkmamıştır. Sonuçlar, ELISA testleri ile doğrulanmıştır. WMV-2 ile infekteli olduğu saptanan bitkilerden elde edilen total RNA’ lar, RT-PCR çalışmalarında kullanılmış ve 408 bp büyüklüğe sahip band % 1’ lik agaroz jelde elektroforez yöntemi ile gözlenmiştir.

Biological, Serological and Molecular Detection of Watermelon Mosaic Virus (WMV-2) in Watermelon Growing Fields in Eastern Mediterranean Region

Öz

This study was carried out with the aim of biological, serological and molecular detection and ide1ntification of WMV-2 in watermelon growing fields in Adana, Mersin and Osmaniye provinces in the spring and summer months of 2012. The presence of WMV infection in collected 182 samples was firstly investigated by ELISA and infection ratio was determined as 46.7%. Selected WMV-2 isolates were used in mechanical inoculation and RT-PCR studies. In mechanical inoculation studies, squash (Cucurbita pepo L.), melon (Cucumis melo L.), cucumber (Cucumis sativus L.) and watermelon (Citrillus lanatus (Thunb.) Matsum.&Nakai) produced mosaic, mottle, deformation and vein banding while C. quinoa Willd., C. amaranticolor Coste and Reynier and G. globosa L. showed chlorotic local lesions of leaves. WMV-2 did not induce any symptoms in tobacco species (N. tabacum L., Nicotiana benthamiana L., N. glutinosa L. and N. rustica L.). The results were confirmed by ELISA. Total RNAs were used in RT-PCR and respected size of DNA band (408 bp) was observed by 1% agarose gel electrophoresis.
