Ovule Ontogenesis And Megagametophyte Development In Onobrychis Schahuensis Bornm. (Fabaceae), Abdolkarim Chehregani, Nayereh Tanomi
Turkish Journal of Botany
The ovule ontogenesis and the megasporogenesis events in Onobrychis schahuensis Bornm. were studied with light microscopy. The primordium is tetra-zonate and gives rise to an anatropous ovule. The archesporium may consist of one or more archesporial cells, but only one of them undergoes meiosis, forming a linear shaped tetrad. Normally, only a single megaspore is functional, which is located in the chalazal position, while the others degenerate very soon. The young ovule is hemianatropous but the mature one is anatropous, crassinucellar, and bitegmic; integuments form a zig-zag micropyle. A 7-celled embryo-sac is formed corresponding to the Polygonum type. The present …

Phylogenetic Relationships Of Some Turkish Crocus (Iridaceae) Taxa Based On Morphological And Anatomical Characters, Fati̇h Coşkun, Selami̇ Selvi̇, Fati̇h Satil
Turkish Journal of Botany
In this study, relationships among the 15 taxa of the genus Crocus L. distributed in Turkey were analysed using 29 morphological and 4 anatomical characters. Analysis of the data set utilising maximum parsimony criterion with Branch-and-Bound search algorithm yielded 32 most parsimonious trees. Bootstrap analysis with the majority rule consensus algorithm generated a consensus tree supporting some branches. Our data mostly did not agree with the previous sectional and serial treatments. The most interesting result was the condition of Crocus pallasii, which was previously included in the section Crocus. C. pallasii showed a sister group relationship with C. cancellatus from …
High Frequency Plant Production Via Shoot Organogenesis And Somatic Embryogenesis From Callus In Tylophora Indica, An Endangered Plant Species, Aastha Sahai, Anwar Shahzad, Mohammad Anis
Turkish Journal of Botany
An efficient and reproducible protocol has been developed for the in vitro production of an endangered medicinal climber Tylophora indica (Burm.f.) Merr. via leaf explants. Different types of calli produced on benzyladenine (BA) and thidiazuron (TDZ) supplemented Murashige and Skoog (MS) basal medium were selected for shoot induction and somatic embryogenesis studies. Calli when transferred from BA (5 µM) and TDZ (2.5 µM) to MS medium containing BA (5 µM) resulted in high frequency shoot induction (26.8 ± 0.97 shoots/culture) along with somatic embryogenesis (10.20 ± 0.37 embryoids/culture) up to 3 subculture passages. Embryoids transformed into complete plantlets when transferred …

Turkish Journal of Botany
Twenty-three populations belonging to 10 wild Primula L. (Primulaceae) taxa of Turkey, some of which are morphologically quite similar, were investigated based on nrDNA ITS regions. The plant materials were collected from different geographical areas of Anatolia in vegetation periods of 2005 and 2006. Total genomic DNAs were isolated from the healthy leaves of each population. The entire ITS regions of the populations were amplified by universal primers with the aid of a polymerase chain reaction (PCR), and then the PCR products were sequenced. Neighbour-Joining (NJ) and Maximum Parsimony (MP) trees were constructed in order to identify the relationships among …

Turkish Journal of Botany
The genus Cyclotrichium, a member of the tribe Mentheae subtribe Menthinae (Lamiaceae, Nepetoideae), was analysed with respect to morphological revision, phylogenetic analysis, and cytogenetic properties. All species of the genus were investigated for morphological characters and ITS (internal transcribed spacers) of nrDNA sequence comparison (except C. hausknechtii for ITS). Six members of the genus were also analysed for chromosome numbers. The combined results strongly suggested that Cyclotrichium is a separate genus in Nepetoideae with distinct morphological, phylogenetic, and cytogenetic characteristics. For intrageneric phylogeny of Cyclotrichium, 3 groups were recognised: 1. C. niveum; 2. C. origanifolium; and 3. the remaining 6 …

Re-Evaluated Conservation Status Of Salvia (Sage) In Turkey I: The Mediterranean And The Aegean Geographic Regions, Ferhat Celep, Musa Doğan, Ahmet Kahraman
Turkish Journal of Botany
The precise evaluation of the conservation status of endemic and rare species is necessary in order to prevent their extinction. According to our current taxonomic revision of Turkish Salvia L., the Mediterranean and Aegean geographic regions of Turkey have 60 taxa, 32 of which are endemic (mainly local endemics), 5 of which are non-endemic rare, and the remaining 23 taxa are widely distributed. The rate of endemism is 53% in the area. The destruction of habitat through human encroachment such as urbanisation, land clearing, overgrazing, pollution, and road and dam constructions is the principal threat in the study area. Based …

Comparative Pharmacognostic Studies On The Barks Of Four Ficus Species, K Babu, Gokul Shankar Sabesan, Sadananda Rai
Turkish Journal of Botany
The barks of 4 Ficus species, namely F. racemosa, F. virens, F. religiosa and F. benghalensis, are important ingredients in many Ayurvedic and traditional formulations. The barks are considered to be very effective in various treatments, such as diabetes, skin diseases, ulcers, and nervous disorders. During market research, we observed that various species of Ficus barks were sold in Indian market under traditional names, such as Plaksah, Udumbarah, Asvatthah, and Vatah. The barks of the species mention above are usually interchanged or adulterated with other species of Ficus because of the limited knowledge in identification and differentiation. Therefore, a detailed …

Embryological And Cytochemical Features Of Scilla Autumnalis L., Zeynep Mi̇ne Coşkun, Meral Ünal
Turkish Journal of Botany
Nucellar epidermal cells in the micropylar region of Scilla autumnalis L. differentiate into a nucellar cap. It secretes a PAS-positive exudate filling the micropyle. A group of cells at the chalazal end of the nucellus forms a hypostase. Close to the antipodals, the hypostase cells contain abundant starch grains, suggesting a function as a storage tissue. Another ovular structure is the obturator. It secretes an exudate that stains deeply with PAS reaction, and it takes a role in directing the growth of pollen tubes toward the micropyle. Cytochemical tests in the mature embryo sac indicate the presence of high amounts …
