Presence of Tomato Spotted Wilt Virus Between Cress and Pepper Intercropped in Kumluca District of Turkiye

Öz

Tomato spotted wilt virus (TSWV) transmits via thrips and causes significant diseases in Solanaceae species. In this study, samples were collected to identify TSWV and determine its frequency in cress (Lepidium sativum) and pepper (Capsicum annum) grown in 27 different greenhouses at Kumluca, Antalya province. More than 102 plant samples of cress and pepper plants were collected in Autumn 2023, these samples showing symptoms of virus-like ring spot and leaf decay, they were tested for the presence of TSWV using RT-PCR and qRT-PCR. Positive cress and pepper samples were discovered and TSWV cases in cress plants were common in 5 greenhouses. Based on the result, this is the first report of TSWV infection in cress. In conclusion, the role of thrips species in virus epidemiology in Turkey should be focused on with the potential of the tested TSWV isolates to break the resistance mechanisms in their hosts increases interspecies epidemic risks

Türkiye'nin Kumluca İlçesinde Yetiştirilen Tere ve Biber Arasında Domates Benekli Solgunluk Virüsünün Varlığı

Öz

Domates benekli solgunluk virüsü (TSWV), thrips yoluyla bulaşmakta ve Solanaceae bitkilerinde önemli hastalıklara neden olmaktadır. Bu çalışmada, Antalya ilinde Kumluca'da bulunan 27 farklı serada yetiştirilen tere (Lepidium sativum) ve biberde (Capsicum annum) TSWV'nin tespit edilmesi ve görülme sıklığının belirlenmesi amacıyla örnekler toplanmıştır. 2023 Sonbaharında tere ve biber bitkilerinden 102'den fazla bitki örneği toplanmıştır. Virüs benzeri halkalı leke ve yaprak bozulması belirtileri gösteren örnekler, TSWV'nin varlığı açısından RT-PCR ve qRT-PCR kullanılarak test edilmiştir. Pozitif saptanan tere ve biber örnekleri ayırt edilmiş ve tere bitkilerinde TSWV vakası 5 serada yaygın olarak görülmüştür. Bulgular ışığında, bu çalışma teredeki TSWV enfeksiyonuna ilişkin ilk rapordur. Sonuç olarak, Türkiye'deki virüs epidemiyolojisinde thrips türlerinin rolüne odaklanılmalı, test edilen TSWV izolatlarının konukçularındaki dayanıklılık mekanizmalarını kırma potansiyeli türler arası epidemik riskleri arttırmaktadır.
