Pollen and Achene Morphology of Some Centaurea L. Taxa (Asteraceae), Turkey Mellifera 2018, 18(2):26-36 MELLIFERA RESEARCH ARTICLE Pollen and Achene Morphology of Some Centaurea L. Taxa (Asteraceae), Turkey Oktay BIYIKLIOĞLU1*, Talip ÇETER1, Barış BANİ1 1 Kastamonu University, Arts and Sciences Faculty, Department of Biology, Kastamonu, Turkey *Corresponding author e-mail: [email protected] Received: 5th December, 2018; accepted: 15th December, 2018; published: 28th December, 2018 A B S T R A C T Centaurea is one of the largest genus of the family Asteraceae. Turkey is one of the distribution areas of this genus. This genus represented with 194 taxa in Turkey, which 105 of them are endemics. In thi s study, pollen morphology and achene micro and macro morphology of 5 taxa belonging to Centaurea (C. iberica, C. virgata, C. cheirolopha, C. urvelli subsp. urvelli, C. solstitialis subsp. solstitialis) were investigated. The aim of the study was to determine taxonomic value of pollen and achene micro features. Pollen grains of Centaurea taxa observed as isopolar, with tricolporate aperture and subprolate and prolate-spheroidal pollen shape. Polar axis ranges between 30.4-49.9 µm while equatorial axis between 25.7-41 µm. The achene shape was observed as ovoid and oblong in studied taxa. SEM showed that the achene surface had a striate sculpture and was depressed on both latera l surfaces, without rare hairs. The micro characters contain polar axis, equatorial axis, pollen shape, pollen surface ornamentation, 26 intine and exine thickness, achene length, Pappus length, achene surface ornamentation was determined as important features for systematics of taxa.

  • Asteraceae) Taxa from Turkey

(Asteraceae) Taxa from Turkey Neslihan Tasar1, Gulden Dogan2* and Yasar Kiran2 1 Munzur University, Tunceli Vocational School, Department of Organic Agriculture, Tunceli, Turkey 2 Firat University, Science Fac., Biology Department, Elazig, Turkey Received March 29, 2018; accepted May 1, 2018 Summary The somatic chromosome numbers and karyotypes were examined in seven species of genus Cen- taurea L. distributed in Turkey. The chromosome numbers were determined as 2n=2x=16 in C. behen L. and C. solstitialis L.; 2n=2x=18 in C. cynarocephala Wagenitz and C. agregata Fisch. & Mey. ex DC. ssp. agregata; 2n=2x=20 in C. iberica Trev. ex Sprengel; 2n=2x=26 in C. balsamita Lam.; 2n=4x=36 in C. virgata Lam. All of the chromosomes had centromeres at median point (M), median region (m), and submedian region (sm). Sat- ellite chromosomes (sat-chromosomes) were observed only in C. virgata. The findings for each of the analyzed taxa are compared each other and with the results of previous studies. Key words Asteraceae, Centaurea, Chromosome number, Karyotype, Turkey.

  • Centaurea Revisited: a Molecular Survey of the Jacea Group

No attempt at phylogenetic reconstruction has been made since recent revisions in circumscription, and previous reconstructions did not include a good representation of species. A new molecular survey is thus needed. Methods Phylogenetic analyses were conducted using sequences of the internal transcribed spacers (ITS) 1 and 2 and the 5.8S gene. Parsimony and Bayesian approaches were used. Key Results A close correlation between geography and the phylogenetic tree based on ITS sequences was found in all the analyses, with three main groups being resolved: (1) comprising the most widely distributed circum- Mediterranean/Eurosiberian sections; (2) the western Mediterranean sections; and (3) the eastern Mediterranean and Irano-Turanian sections. The results show that the sectional classification in current use needs major revision, with many old sections being merged into larger ones.

  • Systematic Implications of Achene Characteristics in Genera Centaurea L., Cyanus Mill., Psephellus Cass. and Rhaponticoides Vaill
    Bangladesh J. Plant Taxon. 22(2): 125-136, 2015 (December) SYSTEMATIC IMPLICATIONS OF ACHENE CHARACTERISTICS IN GENERA CENTAUREA L., CYANUS MILL., PSEPHELLUS CASS. AND RHAPONTICOIDES VAILL. (ASTERACEAE) 1 MEHMET BONA Department of Botany, Faculty of Science, Istanbul University, Istanbul, Turkey Keywords: Achene; Asteraceae; Scanning Electron Microscopy; Taxonomy. Abstract This study examines the exomorphic achene characteristics of 23 taxa belonging to Centaurea, Cyanus, Psephellus and Rhaponticoides in Asteraceae using light microscope and scanning electron microscope (SEM). The exomorphic characteristics studied are shape, size, colour and surface pattern of achene, and hair, length and colour of pappus. The results of the present investigation showed that achene size of the studied taxa is 3–7 × 1–4 mm. Pappus length is 1–14 mm, deciduous for three taxa and inner row is differentiated from the outer, 1–3 mm long, for 10 taxa. SEM studies showed eight different types of achene surface patterns for the studied taxa: Glebulate, glebulate-ruminate, reticulate, ribbed, ruminate, smooth, smooth-glebulate and undulate. Achene characteristics are useful for both intrageneric and intraspecific classification of the studied taxa. Introduction Morphological and anatomical studies on fruit and seed structure play an important role in systematics (Kumar et al., 2012). Microstructural details of the seed and fruit coat enable the distinguishing of taxa or the discovery of their affinities. This is especially useful for families in which the identification of particular taxa is complicated (Kumar et al., 2012; Bona, 2013; Piwowarczyk et al., 2014). Furthermore, observations of micromorphological features can also provide us with information about developmental strategies, adaptation to different environmental conditions and evolutionary tendencies within related groups of plants (Kreitschitz and Vallès, 2007; Moazzeni et al., 2010).

  • Two New Species of Centaurea (Compositae, Cardueae) from Turkey
    Willdenowia 36 – 2006 423 GERHARD WAGENITZ, FRANK H. HELLWIG, GERALD PAROLLY & LUDWIG MARTINS Two new species of Centaurea (Compositae, Cardueae) from Turkey Abstract Wagenitz, G., Hellwig, F. H., Parolly, G. & Martins, L.: Two new species of Centaurea (Compositae, Cardueae) from Turkey. – Willdenowia 36 (Special Issue): 423-435. – ISSN 0511-9618; © 2006 BGBM Berlin-Dahlem. doi:10.3372/wi.36.36139 (available via http://dx.doi.org/) Two new species of Centaurea collected by R. Ulrich in southern Anatolia are described, mapped and illustrated. C. ulrichiorum is apparently very isolated and cannot be assigned to any of the known sections; molecular data place it in a clade comprising, e.g., the sections Jacea and Acrolophus. C. werneri is a member of C. sect. Acrolophus with affinities to species of the Balkans. Key words: angiosperms, Asteraceae, Anatolia, ITS, ETS, systematics, endemism. Introduction Centaurea L. is one of the largest genera in the flora of Turkey. This holds true even if the new, re- vised system is accepted that excludes Rhaponticoides Vaill., Psephellus Cass. and Cyanus Mill. (Wagenitz & Hellwig 2000, Greuter 2003). Since the last revision for the Flora of Turkey (Wagenitz 1975a) the following new species of Centaurea s.l. have been added (literature cita- tions are given for the newly described species): Centaurea amplifolia Boiss. & Heldr. ≡ Rhaponticoides amplifolia (Boiss. & Heldr.)

Its affinities within the genus are discussed. The new species is closely related to R. wagenitziana and R. aytachii from which we delimit it. Rhaponticoides gokceoglui is readily distinguished from those species by its entirely leafy stem, lacking a distinct appendage on phyllaries, ovate outer and ovate- oblong to oblong middle phyllaries with a very narrow scarious margin, and inner phyllaries cucullate at apex only. Habitat conditions and conservation status of R. gokceoglui are considered. Finally, a distribution map and a key to the pinkish- flowered species of Rhaponticoides in Turkey are provided.
