In recent years, rose bacterial diseases are getting to increase and they cause significant economic losses. The severity and distribution of these problems change every year according to the changing climatic factors, growing areas, the type of roses and the level of being affected by biotic and abiotic factors. In this study, on the 106 rose cultivars located in landscape areas of Konya province was determined different diseases symptoms at various levels by carried out survey studies in 1998-2022 years. As a result of the diagnosis of obtaining bacterial and fungal isolates, bacterial blights (Pseudomonas syringae pv. syringae and P. s. pv. morsprunorum), Xanthomonas hortorum, fire blight (Erwinia amylovora) and crown gal (Rhizobium radiobacter), downy mildew (Peronospara sparsa), rust (Phragmodium mucronatum), black spot (Diplocarpon rosae), powdery mildew (Sphaerotheca pannosa var. rosae), gray mold (Botrytis cinerea) were determined as the pathogen on the rose cultivars. It is thought that the findings obtained from the study will contribute to the future development of rose cultivation by revealing the different pathogens and disease levels in roses as a result of the changing climatical conditions.Öğe Effects of Host Resistance Inducers and Copper-based Bactericides on Plant Growth and Bacterial Canker (Clavibacter michiganensis subsp michiganensis) on Tomato Seedlings(AMER SOC HORTICULTURAL SCIENCE, 2010) Baştaş, Kubilay Kurtuluş[Abstract not Available]Öğe Erwinia amylovora enfeksiyonu sonrası elma, armut ve ayva çeşitlerinde konukçu protein miktarlarının belirlenmesi(2015) Çetin, Şerife; Baştaş, Kubilay KurtuluşAteş yanıklığı hastalığına neden olan Erwinia amylovora, Rosaceae familyasından başta armut, elma ve ayvalarda zararlı bakteriyel bir patojendir. Bu çalışmada, E. amylovora nın 2 virülent izolatının (Ea234-1 ve Ea240-3) farklı elma (Braeburn, Fuji, Gala ve Golden Delicious), armut (Santa Maria ve Williams) ve ayva (Eşme ve Ekmek) çeşitlerinde enfeksiyonu sonucu zamana bağlı olarak toplam protein miktarlarının belirlenmesi amaçlanmıştır. E. amylovora (108 hücre ml-1 ) ile yaprak inokulasyonundan sonraki 24, 36 ve 72. saatlerde örnekler alınmıştır. Enfeksiyonların doğrulanması için, bakteri inokule edilen bitkilerden re-izolasyonlar yapılmış ve etmen biyokimyasal ve moleküler testlerle E. amylovora olarak tanılanmıştır. Toplam protein miktarlarının belirlenmesinde Bradford yöntemi ve SDS-PAGE analizleri için Laemmli yöntemleri kullanılmış, protein ekstraktlarının 595 nm de absorbans değerleri elde edilmiştir. Elde edilen bulgulara göre, elma çeşitlerinde E. amylovora enfeksiyonu sonrası kontrole kıyasla 24. saatte toplam protein miktarının arttığı, 36. ve 72. saatte miktarın azaldığı, Braeburn çeşidinin en yüksek protein miktarına sahip olduğu belirlenmiştir. Armut çeşitlerinde, 24. ve 36. saatlerde toplam protein miktarı artarken, 72. saatte protein miktarının azaldığı ve Santa Maria çeşidinin en yüksek protein miktarına sahip olduğu tespit edilmiştir. Ayva çeşitlerinde, toplam protein miktarının 72. saatte arttığı ve Eşme çeşidinin en yüksek protein miktarına sahip olduğu belirlenmiştir. SDS-PAGE analizi sonucunda, farklı molekül ağırlıklarına sahip protein fraksiyonları elde edilmiştir. Elma ve ayva çeşitlerinde sırasıyla yaklaşık 55-70 ve 35-55 kDa, armut çeşitlerinde ise yaklaşık 55-70 kDa molekül ağırlığında protein bantları belirlenmiştir.Öğe Plant Viruses and Plant Growth Promoting Rhizobacteria (PGPR) Relationships: A Shiny Application(Selçuk Üniversitesi, 2022) Öncü, Faruk; Baştaş, Kubilay KurtuluşIn the face of climate change, the point of view of existing agricultural production systems is changing, and biological issues are gaining importance in terms of sustainable agriculture. Environmentally friendly biological solutions come to the forefront in the management of diseases and pests that put pressure on sustainable agriculture. It has been proven by many studies that plant growth promoting rhizobacteria (PGPR) have positive effects on plant growth, as well as reduce or prevent viral diseases. However, determining the targeted virus species, the PGPR strains used, or the plant strains tested requires a serious literature review and reading. In this study, which can be considered as a preliminary study, a database of PGPR and plant virus relations literature was created in a dynamic infrastructure that can be constantly updated, and a web interface was developed as an R/shiny application. Thanks to this preliminary study, which has examples in different fields, it is thought that it is possible for researchers to quickly access the literature on the subject, plan costeffective projects, and identify the missing or potential points of the subject. According to the information in the database, it was determined that CMV was the most targeted virus, different strains of Bacillus and Pseudomonas genera were used the most as PGPR agent, tomato (Solanum lycopersicum) and cucumber (Cucumis sativus) were the most tested plant species, and single applications were tested more. It is thought that this and similar studies will enable researchers to gain a quick perspective on the subject, facilitate the management of the information they have acquired, and contribute to effective planning in their new studies.Öğe Simultaneous occurence of bacterial pathogens, Agrobacterium vitis, A. tumefaciens and Xylophilus ampelinus, on the same grapevine and various cultivars(AMER PHYTOPATHOLOGICAL SOC, 2009) Baştaş, Kubilay Kurtuluş; Altınparmak, Sebahat[Abstract not Available]
