Özet
Bu çalışmada ülkemizde doğal olarak yayılış gösteren Jurinea Cass. cinsine ait türlerin morfolojik, karyolojik, palinolojik, ve moleküler özellikleri araştırılmıştır. Ayrıca tür teşhis anahtarı ve betimleri yapılarak habitat özellikleri, IUCN kategorileri ve coğrafik yayılışları verilmiştir. Türkiye Jurinea cinsine ait taksonların polenleri ışık ve taramalı elektron mikroskobunda incelenmiştir. Polenler prolat ve prolat spheroidal tipte, trikolporat ve ornemantasyonu perforattır. Sitogenetik çalışmalar sonucunda Jurinea cinsine ait 14 taksonun kromozom sayısı 2n=34 olarak tespit edilmiştir. Moleküler çalışmalar kapsamında Jurinea cinsine ait taksonların DNA'ları 2XCTAB metodunun modifiye edilmesiyle izole edilmiş ve ITS primerleriyle PCR yapılmıştır. Taksonların ITS bölgelerine ait kısmi sekans dizileri kullanılarak filogenetik analizleri gerçekleştirilmiştir. Jurinea cinsinin nümerik sınıflandırmasında ise morfolojik ve palinolojik çalışmalardan elde edilen verilerin NTSYS-pc programında değerlendirilmesiyle türler arasındaki genetik ilişkiler belirlenmiştir. Jurinea cinsi Türkiye Florasına göre ülkemizde 17 türle temsil edilmektedir. Bu cinse 1999 yılından sonra Jurinea stoechadifolia ve J. cypria türleri yeni kayıt olarak ilave edilmiştir. Yine bu çalışma kapsamında bilim dünyası için yeni olan J. turcica ve J. tortumensis türleri betimlenmiştir. Türkiye Florasına göre ülkemizde yetiştiği kabul edilen J. eriobasis, J. mesopotamica ve J. multiflora türlerinin arazi çalışmaları süresince örnekleri toplanamamıştır ve bu üç türün ülkemizde yetişmediği düşünülmektedir. Ayrıca, ülkemiz için endemik olarak kabul edilen J. ancyrensis'in İran'da da yayılış gösterdiği tespit edilmiştir. Bu revizyon çalışmasının sonucuna göre Jurinea cinsi ülkemizde 18 türle temsil edilmektedir.
In this study, naturally occuring Jurinea Cass. species of Turkey were evaluated by means of morphological, karyological, palynological and molecular features. Habitat features, IUCN categories and geographical distributions of the species were also given with species identification keys and descriptions. Pollens of the taxa belonging to the genus Jurinea in Turkey were examined with light and scanning electron microscopes. Pollens were found to be of the type prolate and prolate spheroidal, tricolporate and their ornamentation were perforate. Cytogenetic studies revealed that, the chromosome number of the 14 taxa studied were all found as 2n=34. Related to the molecular studies, DNAs were isolated according to 2XCTAB procedure, with minor modifications, and PCRs were conducted in the presence of ITS primers. Phylogenetic analyses were performed based on partially sequenced ITS regions. Numerical classification of the genus Jurinea, based on morphological and palynological data, were also conducted and genetic relationships of the species were determined via NTSYS-pc programme. According to Flora of Turkey the genus Jurinea is represented with 17 species. The species Jurinea stoechadifolia and J. cypria were added as new records in 1999. Also, in the present study, J. turcica and J. tortumensis were introduced to the scientific world as new species. During our field trials, it was not possible to collect any samples from the species J. eriobasis, J. mesopotamica and J. multiflora, while these species were given as natural inhabitants in the Flora of Turkey. Hence, it was concluded that these plants are not grown in Turkey. Furthermore, J. ancyrensis, accepted as an endemic species in our country, was determined to be also present in Iran. According to this revision study, the genus Jurinea is represented with 18 species in our country.
