Steril fungus
olarak da bilinen Pyrenochaeta
lycopersici
, domates yetiştiriciliği yapılan ılıman iklim kuşağındaki pek
çok alanda, %40-70 arası ürün kaybına sebep olan önemli bir patojen fungustur. P. lycopersici tarafından oluşturulan
domates mantarımsı kök hastalığının etkin kimyasal mücadelesi bulunmamaktadır.
Bu çalışmada, Hatay ilinde domates yetiştiriciliği yapılan alanlardan elde
edilen P. lycopersici izolatlarının
virülens düzeyleri ve moleküler tipleri araştırılmıştır. 2015 yılında Hatay
iline bağlı domates yetiştirilen alanlarda survey çalışmaları gerçekleştirilmiş
ve bu esnada solgunluk, sararma ve kök çürüklüğü görülen bitkilerden örnekler
alınmıştır. Yarı seçici besi ortamında yapılan izolasyonlarda 17 P. lycopersici izolatı elde edilmiş ve
teşhisleri ITS1/4 sekansı ile moleküler olarak doğrulanmıştır. Plyc1 ve Plyc2
spesifik primerleri ile yapılan PCR işlemi sonrasında izolatların 3’ünün
moleküler Tip1 ve 14’ünün ise Tip2 olduğu tespit edilmiştir. Domates fideleri
ile kültür filtrat yöntemi kullanılarak patojenisite testi
gerçekleştirilmiştir. Oluşan hastalık simptomları 0-4 skalası kullanılarak
değerlendirilmiş ve skala değerleri McKinney formülü kullanılarak McKinney
indeksi değerlerine dönüştürülmüştür. Patojenisite testi sonucunda hastalık
şiddeti izolatlar arasında farklılık göstermiştir (65-95). Moleküler tip ile
izolatların virülenslikleri arasında herhangi bir ilişki bulunmadığı ancak
izolatların elde edildikleri lokasyon ile virülenslikleri arasında hafif bir
ilişkinin bulunduğu tespit edilmiştir.

Pyrenochaeta
lycopersici
is one of the most important fungal
plant pathogen, which is known as sterile gray fungus on tomato and causes
severe yield loss up to 40-70% in most of the temperate tomato growing areas.
There is no effective chemical control methods of corky root of tomato caused
by P. lycopersici. In this study, we
examined variability of virulence and molecular types in P. lycopersici isolates from tomato in Hatay province of Turkey. In
2015, surveys were carried out in tomato growing areas of Hatay province of
Turkey and infected plant samples showing wilting, yellowing and root rot
symptoms were collected. After isolations on semi selective medium, a total of
17 Pyrenochaeta lycopersici isolates
were collected and verified by ITS1/4 sequence. PCR process with Plyc1 and
Plyc2 specific primers showed that 3 isolates were molecular Type1 and 14
isolates were Type2. To assess of virulence level of Pyrenochaeta lycopersici, a pathogenicity test was conducted with
tomato seedlings by culture filtrate method. Disease symptoms were measured
with a scale of 0-4 and the index were transformed to McKinney index. According
to McKinney index, disease severity varied among isolates (65 to 95). There was
no relationship between molecular types and virulence level but we detected
slight relationship between location and virulence in this study.
