Öğe Efforts to harmonize and promote a stone fruit certification scheme in the Mediterranean countries(International Society for Horticultural Science, 1998) Di Terlizzi, B.; Çaglayan, K.; Gavriel, I.; Myrta, A.; Srhiri, M.; Zeramdini, H.; Audergon, J.M.The awareness of potential disastrous consequences to stone fruit crops from virus diseases (i.e. sharka) has set up alarm signals in the scientific community and has prompted the initiation of national and international projects for the production of virus-free stocks through certification programs. To promote a clean stock program in the Mediterranean region, the Centre International de Hautes Etudes Agronomiques Méditerranéennes (CIHEAM) has promoted the "Mediterranean Network for Virus Disease Assessment and Sanitation of Stone Fruit Trees" (MNFT). Various proposals have been discussed to improve and harmonize current certification schemes starting from EPPO stone fruit protocols now in operation in different countries. Other proposals for more reliable techniques for disease detection to be used in these programs are included. The harmonization of a stone fruit clonal selection and certification scheme in the Mediterranean Region is submitted to the attention of the scientific community and/or the agricultural authorities of member Governments.Öğe First report of 'candidatus phytoplasma asteris' (group 16sri-b) infecting sweet cherries in Turkey(2013) Çaglayan, K.; Gazel, M.; Küçükgöl, C.; Paltrineri, S.; Contaldo, N.; Bertaccini, A.Five-year-old sweet cherry (Prunus avium L.) trees, exhibiting symptoms typical of phytoplasma diseases were observed in the Turkish province of Usak during 2011. The percentage of symptomatic plants, scattered in the orchards, was nearly 40%. Samples were collected during late spring and early summer from trees showing proliferation of branches, off season flowering and decline. In order to establish phytoplasma association with these symptoms, nucleic acid was extracted from leaf midribs of 10 symptomatic and five symptomless plants. Nested PCR assays using universal phytoplasma primers P1/P7 followed by R16F2n/R2 and by 16R758f/16R1232r (Duduk et al., 2013) provided positive responses for seven of the symptomatic samples. Restriction fragment length polymorphism (RFLP) analysis was performed on PCR products using restriction enzymes Tsp509I, Tru1I and AluI. Preliminary RFLP identification was confirmed by nested PCR assays with primers R16(I)F1/R1 (Lee et al., 1994) followed by RFLP analysis, that allowed phytoplasma classification in the 16SrI-B subgroup. Since all amplicons showed identical restriction profile, according to the enzymes and primers employed, one of them was sequenced in both directions using primers R16(I)F1 and R16(I)R1. The 1,006 nucleotide long sequence, deposited in GenBank under the accession No. KF476062, showed 99.0% identity with 16S rDNA from several phytoplasmas related to 'Candidatus Phytoplasma asteris', including strains associated with cherry little leaf (GenBank AY034089) and cherry bunchy leaf (Gen- Bank HM067754), that are affiliated to a different 16SrI subgroup (Jomantiene et al., 2011). This is the first report of 'Ca. P. asteris' infecting sweet cherries in Turkey.Öğe First report of little cherry virus 1 in Turkey(2011) Ulubas Serçe, C.; Gazel, M.; Çaglayan, K.[No abstract available]Öğe Transmission of the fig mosaic agent by the eriophyd mite Aceria ficus cotte (Acari: Eriophyidae)(2009) Çaglayan, K.; Medina, V.; Yigit, A.; Kaya, K.; Gazel, M.; Serçe, Ç.U.; Çaliskan, O.[No abstract available]
