Öğe Antifungal Effects of Essential Oils on Mycelial Growth, Conidia Germination and Morphology of Hyphae of Gray Mold Disease Agent Botrytis cinerea(Kahramanmaras Sutcu Imam Univ Rektorlugu, 2023) Kose, Fatih; Soylu, Emine MineBotrytis cinerea, which causes gray mold disease, is a fungal disease agent with a wide host range, including citrus fruits. In this study, antifungal effects of plant essential oils obtained from different thyme species (Origanum onites L., Origanum syriacum Holm., Thymbra spicata L.) and fennel (Foeniculum vulgare Mill.) in vapor phase were investigated on mycelial growth, conidia germination and morphology of hyphae of B. cinerea in vitro conditions. Among the essential oils, the highest antifungal activity (100% inhibition) was detected at the dose of 10 mu g mL-1 of O. onites and O. syriacum essential oils, and these applications were followed by T. spicata at a dose of 40 mu g mL-1 and F. vulgare essential oil at a relatively higher dose (120 mu g mL-1) used. The effectiveness of essential oils at doses that completely inhibit mycelial growth were determined as fungicidal. All essential oils tested completely inhibited the germination of fungal conidia at the dose of 10 mu g mL-1. In scanning and light microscopy studies, it has been observed that essential oils cause serious deteriorations such as vesiculation, cytoplasmic coagulation and lysis on fungal mycelium and conidia at minimum inhibition concentrations determined. Microscope observation results showed that the antifungal activities were due to the morphological deteriorations caused by the essential oils on the fungal hyphae and conidia. Overall results showed that essential oils of thyme species have the potential to be used as environmental friendly biofungicide alternative to chemicals against fungal diseases in stored products.Öğe Assessment of glucosinolate-derived isothiocyanates as potential natural antifungal compounds against citrus sour rot disease agent Geotrichum citri-aurantii(Wiley, 2020) Kara, Merve; Soylu, Emine MineIn this study, the antifungal effects of six different isothiocyanate (ITCs) compounds (methyl, allyl, butyl, ethyl, benzyl and 2-phenylethyl ITCs) were investigated to be use against the citrus sour rot disease caused by Geotrichum citri-aurantii in vitro and semi-commercial (in vivo) conditions. Antifungal activities of the vapour phases of different ITC compounds were examined on the arthroconidia germination and mycelial growth of G. citri-aurantii. Mycelial growth of G. citri-aurantii was inhibited in a concentration-dependent way. The minimum inhibitory concentrations of benzyl, methyl, allyl and ethyl ITCs on mycelial growth were 0.06, 0.08, 0.10 and 0.10 mu l/L, respectively. Arthroconidia germination of G. citri-aurantii was completely inhibited by benzyl, methyl, allyl and ethyl ITCs at concentrations of 0.05, 0.07, 0.07 and 0.07 mu l/L, respectively. Light microscopy observations revealed that the ITC compounds, at completely inhibiting concentrations, caused considerable morphological changes in the fungal hyphae. Under in vivo conditions, the average rotting area caused by G. citri-arantii was inhibited 100% by ethyl, methyl and allyl ITC compounds at concentrations of 8.0, 12.0 and 12.0 mu l/L, respectively. Results suggest that ITC's may be useful and effective natural antifungal compounds to control the citrus sour rot disease agent.Öğe Bazı Fidanlıklarda Görülen Toprak Kökenli Fungusların Belirlenmesi(2021) Uysal, Aysun; Kurt, Şener; Kara, Merve; Soylu, Soner; Soylu, Emine MineGaziantep Orman Fidanlık Şefliği, Osmaniye Orman Fidanlık Şefliği, Hatay Serinyol Orman Fidanlık Şefliği ve HMKÜ kampüs fidanlık alanında 14 farklı peyzaj bitkisi türünden toplam 98 adet hastalıklı fidan örneği toplanmıştır.

Çalışmanın Önemi ve Etkisi: Sonuç olarak, fluazinam, thiophanate-methyl ve tebuconazole’ün fungal patojen B. dothidea’nın kontrolünde kullanım potansiyeli bulunduğunu ortaya koymaktadır.Öğe Chemical composition and antibacterial activity of essential oils isolated from medicinal plants against gall forming plant pathogenic bacterial disease agents(Kahramanmaraş Sütçü İmam Üniversitesi, 2020) Bozkurt, İmam Adem; Soylu, Soner; Kara, Merve; Soylu, Emine MineThe aims of this study were to determine chemical composition of essential oils from different plant species and their antibacterial activities against gal-forming plant pathogenic bacterial disease agents Rhizobium radiobacter, Pseudomonas savastanoi pv. savastanoi and P.savastanoi pv. nerii. The chemical compositions of essential oils were identified by GC/MS. The major constituents of the essential oils were carvacrol in Thymbra spicata var. spicata (66.88%) and Origanum syriacum (79.8%), thymol in Thymus serpyllum (41.03%), geranial in Thymus sipyleus (13.72%) and Melissa officinalis (30.4), 4-terpineol in Origanum majorana (31.67%), linalool in Ocimum basilicum (30.23%), carvone in Mentha spicata (55.58%), 1,8 cineole in Lavandula stoechas var. stoechas (35.5%), Laurus nobilis (35.5%) and Rosmarinus officinalis (18.47%), camphor in Salvia officinalis (24.59%) and trans-anethole in Foeniculum vulgare (82.8%) essential oils, respectively. Based on inhibition zone diameter values, essential oils showed very strong antibacterial activities against P.savastanoi pv. savastanoi (7.0-44.67 mm), followed by R.radiobacter (9.6-37.67 mm) and P.savastanoi pv. nerii (6.33-18.33 mm). Essential oils of plants belong to Lamiaceae family were generally found to be more efficient than those belong to Lauraceae and Apiaceae families. The essential oils of O.syriacum, T.serpyllum and T.spicata var. spicata were found to be the most promising essential oils displaying the highest antibacterial activities against all tested bacterial species. The findings of the present study revealed that essential oils have a potential to be used as antibacterial agents against gall forming bacterial disease agents.Öğe Determination of antagonistic potential of endophytic bacteria isolated from lettuce against lettuce white mould disease caused by Sclerotinia sclerotiorum(Lithuanian Research Centre Agriculture & Forestry, 2021) Soylu, Soner; Kara, Merve; Uysal, Aysun; Kurt, Sener; Soylu, Emine MineIn this study, biocontrol efficiency of endophytic bacterial isolates obtained from the leaf lettuce (Lactuca sativa L.) healthy plants was investigated against white mould disease agent Sclerotinia sclerotiorum in vitro and in vivo conditions. Antagonistic efficiency of endophytic bacterial isolates was determined to inhibit mycelial growth and sclerotial germination, suppress disease incidence caused by S. sclerotiorum. A total of 48 endophytic bacterial isolates were isolated from different tissues of lettuce healthy plants. Mycelial growth and germination of sclerotia of S. sclerotiorum in vitro inhibited 18 bacterial isolates. Bacillus subtilis and B. amyloliquefaciens isolates were found to be the most efficient ones, which significantly inhibited the mycelial growth by 68.1-83.1%, germination of sclerotia by 82.7-89.6% and suppressed disease incidence by 55.7-75% caused by S. sclerotiorum. In addition, the fungal mycelium close to the inhibition zone in dual culture was denser and darker in colour. B. subtilis and B. amyloliquefaciens isolates caused significant morphological alterations in hyphae such as hyphal shrivelling and perforation close to the inhibition zone in dual culture. Significant suppression in the mycelial growth, sclerotial germination and disease incidence caused by endophytic bacterial isolates indicate that isolates of B. subtilis and B. amyloliquefaciens could be considered as possible biocontrol agents against soil-borne fungal diseases.Öğe Determination of Biocontrol Potentials of Endophytic Bacteria in Biological Control of Citrus Sour Rot Disease Caused by Geotrichum citri-aurantii(Univ Namik Kemal, 2022) Soylu, Soner; Kara, Merve; Soylu, Emine Mine; Uysal, Aysun; Kurt, SenerCitrus fruits are susceptible to postharvest decays caused by various pathogenic fungal disease agents. Citrus sour rot, caused by Geotrichum cirri-aurantii is one of the most important postharvest diseases of citrus fruits Although synthetic fungicides are commonly used to combat the disease, ineffectiveness of these applications as well as their harmful effects on human health and the environment have been reported in many studies recently. Biological control of postharvest diseases utilizing antagonistic bacteria has been explored in different host plant-pathogen interactions as a promising alternative to synthetic fungicides. In this study, biocontrol potentials of endophytic bacterial isolates, obtained from fruits, branch and leaves of healthy citrus trees, were investigated against Geotrichum citri-aurantii on petri plates (in vitro) and fruit tests (semi in vivo conditions). Among the 24 putative endophytic bacterial isolates isolated, sixteen different antagonist bacterial isolates were selected and assessed against mycelial growth inhibition of G. citri-aurantii in vitro studies. Among the bacterial isolates tested, Bacillus spp. isolates significantly inhibited mycelial growth of fungal agent by 59.5-78.6%. The highest mycelial growth inhibition was caused by B. subtilis CM8 (78.6%). Bacterial isolates of Acinetobacter johnsonii CT7, Erwinia herbicola CM5, Pseudomonas putida CL2, Pantoea agglomerans CM14, Acinetobacter lwoffii CP1 and Stenofrophomonas maltophilia CP3 failed to inhibit mycelial growth in dual culture assays. Antagonistic activities of bacterial isolates increased by the pre-incubation time before fungal inoculation. Bacterial isolates of Bacillus spp. caused considerably morphological changes such as vacuolation, shrivelling, swelling and lysis of hyphae close to inhibition zone. On artificially inoculated fruits, isolates of Bacillus spp. also found to suppressed disease incidence significantly by 56.7-83.3%. Due to strong antagonistic activities, isolates of Bacillus spp, tested in this study have the potential to be used as biofungicide for controlling post-harvest disease agent(s) of citrus fruits.Öğe Determination of Fungal and Bacterial Disease Agents on Significant Brassicaceous Vegetable Species Grown in Hatay Province(Kahramanmaras Sutcu Imam Univ Rektorlugu, 2024) Soylu, Soner; Kara, Merve; Uysal, Aysun; Gumus, Yusuf; Soylu, Emine Mine; Kurt, Sener; Uremis, IlhanThe Brassicaceae family, commonly known as the Cruciferae or mustard family, encompasses plant species of global economic significance, including oilseed crops, vegetables, as well as condiment purposes. Hatay is one of the most important provinces in Turkey where Brassicaceous vegetable crops are grown. This study aimed to identify the causative disease agents affecting Brassicaceous vegetables including cabbage (red and white varieties), broccoli, cauliflower, garden cress, rocket, and radish in the districts of Hatay Province where vegetable cultivation took place during the 2020-2021 growing seasons. Isolations from suspicious cabbage, broccoli, cauliflower, and radish plants exhibiting disease symptoms in the surveyed areas revealed the presence of various fungal disease agents, including Rhizoctonia solani, Sclerotinia sclerotiorum, Fusarium solani, Fusarium oxysporum, Fusarium exquisite, Alternaria alternata, Botrytis cinerea, , and Stemphylum sp. Furthermore, obligate oomycete pathogens such as Albugo lepidii, Albugo candida, , and Perofascia lepidii were detected with varying prevalence and incidence rates on leaves and stems of water cress, rocket, and radish plants. In addition to fungal pathogens, primary bacterial pathogens, including Xanthomonas campestris pv. campestris, , Pectobacterium carotovorum subsp. carotovorum, , Pectobacterium parmentieri, Pseudomonas corrugata, , and Pseudomonas victoria, , were identified through morphological, biochemical, and pathogenicity tests, and MALDI-TOF analyses. Pantoea agglomerans, Pseudomonas marginalis, Pseudomonas fluorescens, Enterobacter cloacae, and Bacillus pumilus were also identified as opportunistic soft rot bacterial pathogens. To the best of our knowledge, this is the first report of F. solani, F. oxysporum, F. exquisite, A. alternata, B. cinerea, Stemphylum sp., as fungal disease agents; P. parmentieri, P. corrugata, and P. victoria as primary soft rot bacterial disease agents; P. agglomerans, P. marginalis, P. fluorescens, E. cloacae, and B. pumilus as opportunistic secondary soft rot bacterial disease agents affecting different minor vegetables belong to Brassica spp, such as cabbage (red and white varieties), broccoli, cauliflower, radish, rocket, and garden cress, grown in Turkey.Öğe Determination of Fungal and Bacterial Diseases Agents Encountered in Carrot Growing Fields in Amik Plain of Turkey(Kahramanmaras Sutcu Imam Univ Rektorlugu, 2022) Soylu, Soner; Kara, Merve; Uysal, Aysun; Kurt, Sener; Soylu, Emine Mine; Uremis, Ilhan; Sertkaya, ErdalCarrot [Daucus carota L.] is one of the most consumed healthy vegetables worldwide due to its vitamins, amino acids and high nutritional content. Fungal and bacterial disease agents, encountered in the fields where carrots are grown in the Amik Plain of Hatay province, were determined during 2018-2019 growing season. Disease surveys were carried out at three different phenological stages of the plant. Different fungal and bacterial disease agents were isolated and subsequently identified from diseased leaves, stems and fruits. In addition to the disease symptoms in the form of transverse brown dry depressions on carrot fruits, from the brown-black spots on the leaves and stems, Alternaria dauci, A. alternata, Rhizoctonia solani, R. carotae, Botrytis cinerea, Sclerotinia sclerotiorum, Geotrichum candidum, Pythium spp., Fusarium bra. equiseti, F. proliferatum and F. solani species were obtained and identified as a result of molecular and MALDI-TOF protein profile analyzes as well as their morphological features.

Total of 69 putative bacterial biocontrol agent (BCA) isolates were obtained from commercial vermicompost lots. Among them, 28 bacterial isolates (49.12% of total isolates) were inhibited mycelial growth of S. sclerotiorum by 1.72-75.43%, M. phaseolina by 1.67-65.83%, B. cinerea by 3.44-57.18%, V dahliae by 2.28-58.74%, respectively. Majorities of bacterial isolates were identified as Bacillus spp. Certain isolates of Bacillus spp. have caused noticeable morphological changes on mycelia of S. sclerotiorum. Antagonistic potentials of bacterial isolates were found to increase by pre-incubation time prior the fungal inoculation. Due to high antagonistic properties, efficient isolates of Bacillus spp. may be used as biocontrol agent against soilborne diseases as an alternative to pesticides to promote organic and sustainable agriculture.Öğe Disease prevalence, incidence, morphological and molecular characterisation of Lasiodiplodia pseudotheobromae causing collar rot disease on peanut plants in Turkey(Springer Heidelberg, 2024) Ozkaya, Senem; Soylu, Soner; Kara, Merve; Gumus, Yusuf; Soylu, Emine Mine; Teke, Ibrahim; Ozcan, Oktay BurakPeanut (Arachis hypogaea L.) holds significant commercial and dietary importance as a major source of edible oil and protein in Turkey. Stem, collar or root rot, caused by several fungal disease agent, are serious soil-borne diseases of peanut. Accurate and precise identification of the disease agent provides fundamental and precise information for integrated plant management. During the period from June to September 2021, symptoms consistent with collar rot disease, including dark-brown stem rot, chlorotic leaves, wilting, and eventual whole plant death, were observed on peanut plants cultivated in the different districts of Osmaniye Province of Turkey. The disease incidence ranged from 8.0 to 45.0% in the inspected fields with an average of 3.4% overall. Twenty-four single-spore representative isolates were obtained from surface-disinfected symptomatic tissues. Morphological characteristics of fungal mycelium, conidial and pycnidial structures on potato sucrose agar (PSA) and water agar (WA) closely resembled those described for Lasiodiplodia spp. All isolates caused typical collar rot symptoms upon artificial inoculation of peanut seedlings. Morphological identification of Lasiodiplodia spp. isolates was corroborated by MALDI-TOF and molecular analyses utilizing sequences from the internal transcribed spacer (ITS), beta-tubulin 2 (tub2) and translation elongation factor-1 alpha (TEF1-alpha) loci. Phylogenetic analysis confirmed that the representative fungal isolates (MKUBK-B1 and MKUBK-K22) belong to Lasiodiplodia pseudotheobromae. To the best of our knowledge, this is the first report of L. pseudotheobromae infecting peanut plants in Turkey. This work is expected to contribute to previously limited knowledge regarding the host range, incidence and prevalence of L. pseudotheobromae as a soilborne pathogen of peanuts. Due to the potential destructiveness and broad host range of this pathogen, it is essential to develop new strategies to establish more reliable, environmentally sustainable, and cost-effective management approaches for this disease.Öğe The effects of ethanol-dissolved propolis on the storage of grapefruit cv. Star Ruby(2010) Özdemir, Ahmet Erhan; Ertürk Çandır, Elif; Kaplankıran, Mustafa; Soylu, Emine Mine; Şahinler, Nuray; Gül, AzizPropolis has a strong antimicrobial effect and limits the growth of microorganisms. This study was carried out to determine the effect of propolis on the storage life of Star Ruby grapefruit. Fruits were obtained from Mustafa Kemal University, Faculty of Agriculture, Dörtyol Experimental Research Station, Dörtyol, Hatay, Turkey. Fruits were dipped in ethanol-extracted propolis (EEP) in various concentrations (1%, 5%, and 10%) immediately after harvest and then stored at 8 °C and 90% relative humidity for 6 months. The effects of propolis on the incidence of physiological disorders and fungal decay, and some fruit quality characteristics (weight loss, fruit juice content, total soluble solids, titratable acidity, juice pH, percent of fruits with green calyx, and skin color) were assessed at monthly intervals during the storage period. Treatment with 5% EEP was effective in preventing fungal decay. The percentage of weight loss was significantly higher in the control fruits (6.36%-7.83%) than in those treated with 5% EEP (5.71%) and 10% EEP (4.95%) at the end of the storage period. Star Ruby grapefruit treated with 5% EEP was successfully stored at 8 °C for 5 months.Öğe Effects of modified atmosphere packaging and ethanol vapor treatment on the chemical composition of 'Red Globe' table grapes during storage(Elsevier, 2012) Ustun, Durmus; Candir, Elif; Ozdemir, Ahmet Erhan; Kamiloglu, Onder; Soylu, Emine Mine; Dilbaz, RamazanThe sugar, organic acid, and anthocyanin contents and antioxidant capacity of 'Red Globe' table grapes packaged in perforated polyethylene (PPE) or ZOEpac modified atmosphere packaging (MAP) bags, with or without different grades of ethanol vapor-generating sachets (Antimold (R) 30, Antimold (R) 60 or Antimold (R) 80) or an SO2-generating pad, were evaluated during 3 months of storage at 0 degrees C. Fructose, glucose, malic, and tartaric acid contents remained unchanged in grapes packaged in PPE or ZOEpac bags containing an SO2-generating pad throughout storage. In grapes packaged in PPE or ZOEpac bags with or without Antimold (R) sachets, fructose, glucose, and malic acid contents decreased whereas tartaric acid content increased during storage due to a higher incidence of fungal decay as compared to SO2 treatments. Citric acid content decreased in all treatments during storage. Anthocyanin content increased in the first 2 months of storage and then decreased by the end of storage. An Antimold (R) 80 sachet added to ZOEpac bags resulted in higher anthocyanin content, ferric-reducing antioxidant power (FRAP) and trolox equivalent antioxidant capacity (TEAC) during storage.
