(2015-04-01) Yuzbasioglu M.; Kuruuzum-Uz A.; Guvenalp Z.; Simon A.; Tóth G.; Sebnem Harput U.; Kazaz C.; Bilgili B.; Duman H.; Saracoglu I.; Omur Demirezer L.
Phytochemical studies of the roots and aerial parts of endemic Arnebia purpurea S. Erik &H. Sumbul resulted in the isolation and characterization of four naphthoquinones [isovalerylalkannin (1), α-methyl-n-butanoyl alkannin (2), acetylalkannin (3), and alkannin (4)], a triterpene derivative [3-O-acetyl-oleanolic acid (5)], a steroid [â-sitosterol (6)], three flavonoid glycosides [isorhamnetin-3-O-rutinoside (7), kaempferol-3-O-rutinoside (8), kaempferol 3-O-(5"-acetyl) apiofuranoside 7-O-rhamnopyranoside (9)] and a phenolic acid [rosmarinic acid (10)]. 3-O-Acetyl-oleanolic acid, isorhamnetin-3-O-rutinoside, kaempferol-3-O-rutinoside, and kaempferol 3-O-(5"-acetyl) apiofuranoside 7-O-rhamnopyranoside are reported from an Arnebia species for the first time. Cytotoxic activities on L929 murine fibrosarcoma cell line of the isolated compounds were investigated using MTT assay. Naphthoquinones (1-4) showed intermediate cytotoxic activity in comparison with the standard, doxorubicin.
Dichoropetalum alanyensis (Apiaceae), a new species from South Anatolia, Turkey
(2016-01-01) Bilgili B.; Sağiroğlu M.; Şeker M.; Duman H.
Dichoropetalum alanyensis Bilgili, Sağıroğlu & H.Duman, a new species from South Anatolia in Turkey (Antalya-Alanya), is described and illustrated. It is closely related to D. chryseum (Boiss. & Heldr. ex Boiss.) Pimenov & Kljuykov, from which it differs mainly by its habit, basal leaves and lobes, and mericarp features. Diagnostic morphological characters are discussed. Notes are also given on its ecology and conservation status, together with scanning electron micrographs of mericarp surface sculpturing pattern. ITS sequences were used for DNA fingerprinting. The data were analyzed with the SEAVIEW package. Standardized data were used to generate a dendrogram that revealed the phylogenetic relationships of taxa in tribes Selineae (Dichoropetalum-Johrenia), Tordylieae (Cymbocarpum), and Bupleureae (Diplotaenia) from different localities.
Nonea dumanii sp. nov. (Boraginaceae) from the Taurus mountains (south Turkey)
(2012-10-01) Bilgili B.; Coppi A.; Selvi F.
The new species Nonea dumanii, endemic to the mountains of the western Taurus in south Turkey (C4 Antalya), is described an illustrated based on original collections by the authors. Karyological observations and analysis of ITS1 DNA sequences showed that the species is probably hexaploid with 2n =6x =60 and has phylogenetic affinity to the diploid N. monticola from the Paphlagonian mountains as well as to the tetraploid N. anchusoides from northwest Iran and southeast Turkey. From these allopatric species it is morphologically distinct in characters of the indumentum, flower and fruit. Polyploidy is supported as a major driving force for speciation in Nonea, especially in the group of Anatolian mountain species with primary base number x =10. © 2012 The Authors.

Pollen morphology of the genus Lamium L. (Lamiaceae) and its systematic implications
(2016-01-01) Atalay Z.; Celep F.; Bilgili B.; Doğan M.
This is the first comprehensive palynological investigation of the genus Lamium. The pollen morphology of 48 taxa (including species, subspecies and varieties) of the genus Lamium was investigated and documented using light microscopy (LM) and scanning electron microscopy (SEM). Lamium pollen is small to medium sized (P = 21.65-39.96 μm), oblate-spheroidal to subprolate in shape and tricolpate. Three major exine sculpturing patterns (reticulate, granulate and microreticulate) were observed. The results indicated that the exine sculpturing pattern of Lamium is systematically informative at sectional level, but not at the species and infraspecific levels. In the present study, the palynological data are compared with available phylogenetic studies to evaluate the systematic value of pollen characters in the genus. Analysis show that; (1) Mennema's infrageneric classification is partly corroborated by our palynological data, (2) recent phylogenetic analysis on the genus and our results are partly corroborated, and (3) pollen morphology supports the inclusion of L. galeobdolon (=Galeobdolon), L. orientale and L. multifidum (=Wiedemannia) in Lamium. (4) Variation in exine sculpturing pattern have systematic importance particularly at sectional level.

Taxonomy and IUCN categories of two endemic scrophularia L. (Scrophulariaceae) species cited in the data deficient (DD) category
(2015-09-18) Uzunhisarcikli M.E.; Doğan Güner E.; Bilgili B.
Scrophularia is represented with 59 species in the Flora of Turkey. This study presents the taxonomy and threatened categories of two endemic Scrophularia L. (Scrophulariaceae) species: S. erzincanica R. Mill and S. capillaris Boiss. & Bal. These species were previously placed in the Data Deficient (DD) category according to Red Data Book of Turkish Plants. This study provides the re-descriptions of taxa and suggests new IUCN categories according to IUCN 2010 threatened categories. Descriptions, localities,distribution map and images of the species are also given.
