Euxine elements), 35 taxa (4.71%) are Mediterranean elements, and 320 taxa (43.12%) are multi-regional or are taxa whose phytogeographical regions are unknown. The 3 largest families are Asteraceae (111 taxa), Fabaceae (65 taxa) andBrassicaceae (59 taxa). The 3 largest genera are Astragalus (25 taxa), Centaurea (14 taxa)andSilene (13 taxa).
Zelkova spach. (an ancient tree) is a member of the Ulmaceae family. Zelkova of about six species (Zelkova sicula Di Pasq., Garfì & Quézel, Zelkova abelicea (Lam.) Boiss., Zelkova carpinifolia (Pall.) C. Koch, Zelkova serrata (Thunb) Makino, Zelkova schneideriana Hand.-Mazz. and Zelkova sinica C.K. Schneid.) of deciduous, semi-evergreen trees occurring in written in woodland, thickets and in Italy, Greece, Turkey, Iran and Asia. Zelkova have alternate, ovate to elliptic toothed leaves. Most species display good fall colour of yellows and orange-browns. Zelkova carpinifolia, known as Caucasian elm, Caucasian zelkova or just zelkova is a species of Zelkova, native to the Caucasus, Kaçkar, and Alborz mountains in the extreme southeast of Europe and southwest Asia (Turkey, Azerbaijan, Iran, Georgia, Armenia). Zelkova carpinifolia is highly valued as an ornamental owing to its unusual outline, having a relatively short, wide trunk that divides into many ascending branches. It is rare in many regions and listed as Near Threatened according to IUCN Red List criteria. In Turkey, for example, only a few highly isolated populations are known (Kars, Hakkâri, Siirt, Muş). It seems very probable that other yet undiscovered sites with Z. carpinifolia still exist on Turkey, therefore additional field surveys should be undertaken. Currently there is no legal protection for this species. In this study, the genus of Zelkova, floristic and ecological characteristics were studied. Distribution areas in the world and Turkey is shown on the map and threat categoriesis based on the IUCN Red List criteria. In addition, pictures and images of the Zelkova carpinifolia species is given. Photos are taken in Turkey's Hakkari province. Türkiye'de Zelkova carpinifolia (Pall.) C. Koch (Ulmaceae) (Relikt Ağacı): floristik, ekoloji, dağılım ve tehditler Özet Zelkova spach. (relikt bir ağaç), Ulmaceae familyasının bir üyesidir. Ormanlık ve çalılıklarda yaprak döken ve dökmeyen Zelkova'nın İtalya, Yunanistan, Türkiye, İran ve Asya'da tanımlanmış yaklaşık altı türü vardır (Zelkova sicula Di Pasq., Garfì & Quézel, Zelkova abelicea (Lam.) Boiss., Zelkova carpinifolia (Pall.) C. Koch, Zelkova serrata (Thunb) Makino, Zelkova schneideriana Hand.-Mazz. and Zelkova sinica C.K. Schneid.). Zelkova alternat, ovat-eliptik ve dişli yapraklıdır. Çoğu türü sarı ve turuncu-kahverengi, sonbahar renklerindedirler. Kafkas karaağacı, Kafkas zelkovası ya da sadece zelkova olarak bilinen Zelkova carpinifolia, Kafkasya, Kaçkar, Avrupa ve güneybatı Asya (Türkiye, Azerbaycan, İran, Gürcistan, Ermenistan) güneydoğunun en uçlarında Elburz dağlarının doğal bir Zelkova türüdür. Zelkova carpinifolia çok sayıda yükselen dallara ayrılan nispeten kısa, geniş gövdeli; sıra dışı görüntüsü sayesinde çok iyi bir süs bitkisi olarak değerlendirilir. Pek çok bölgede nadir bulunur ve IUCN Kırmızı Liste kriterlerine göre NT olarak listelenir. Türkiye'de izole halde birkaç populasyonu bilinmektedir (Kars, Hakkâri, Siirt, Muş). Türkiye'de Z. carpinifolia'nın mevcut olduğu henüz keşfedilmemiş yerler hala çok muhtemel görünmektedir, bu nedenle arazi araştırmaları yapılmalıdır. Şu anda bu tür için yasal koruma bulunmaktadır. Bu çalışmada Zelkova cinsinin floristik ve ekolojik karakterleri araştırılmıştır.

Understanding how plants cope with changing habitats is a timely and important topic in plant research. Phenotypic plasticity describes the capability of a genotype to produce different phenotypes when exposed to different environmental conditions. In contrast, the constant production of a set of distinct phenotypes by one genotype mediates bet-hedging, a strategy that reduces the temporal variance in fitness at the expense of a lowered arithmetic mean fitness. Both phenomena are thought to represent important adaptation strategies to unstable environments. However, little is known about the underlying mechanisms of these phenomena, partly due to the lack of suitable model systems. We used phylogenetic and comparative analyses of fruit and seed anatomy, biomechanics, physiology and environmental responses to study fruit and seed heteromorphism, a typical morphological basis of a bet-hedging strategy of plants, in the annual Brassicaceae Aethionema arabicum. Our results indicate that heteromorphism evolved
The composition of the hydrodistilled essential oils obtained from aerial parts of Grammosciadium schischkinii (V.M.Vinogr. & Tamamsch.) V.M.Vinogr., G. haussknechtii Boiss., G. pterocarpum Boiss. and G. platycarpum Boiss. & Hausskn. ex Boiss. (Apiaceae) which belong to subgenus Caropodium, growing in Turkey, were simultaneously analyzed by GC and GC-MS. The analysis revealed fifty-seven constituents, accounting 84.3–99.5% of the oils. The essential oil composition of G. schischkinii and G. haussknechtii which are endemic taxa to Turkey, have herein demonstrated for the first time. Moreover, we firstly defined the chemical characterization of the essential oil obtained from G. platycarpum gathered from Turkey. Oil samples showed different chemical compositions with regard to species and locations. Linalool (88.5 and 94.2%) was the main component of the oil samples from G. platycarpum, while hexadecanoic acid (20.6%) was the major in the oil sample of G. haussknechtii. Caryophyllene oxide (45.9 and 20.7%) was defined as the principal constituent in the oil samples of G. schischkinii and G. pterocarpum, respectively. In addition, phytol (19.1%) was determined as the main component in the oil of G. haussknechtii and this compound was first determined in the highest amount among the essential oils of the genus Grammosciadium.
Essential oils obtained by hydrodistillation from the aerial parts and fruits of five taxa of genus Grammosciadium DC., belonging to subgenus Grammosciadium (G. confertum Hub.-Mor. & Lamond, G. cornutum (Nábělek) C.C.Towns., G. macrodon Boiss. subsp. macrodon, G. macrodon Boiss. subsp. nezaketae B.Bani and G.daucoides DC. ), collected from different locations in Turkey, were simultaneously analyzed by GC and GC/MS systems. 124 components representing 71.1-99.8% of the total contents were identified in the oils. Oil samples from fruits and aerial parts of the plants showed different chemical profiles with regard to species. We have herein demonstrated that the chemical composition of essential oil samples from G. cornutum , G. macrodon subsp. macrodon , G. macrodon subsp. nezaketae (an endemic subspecies) , and G. confertum (an endemic species) growing in Turkey was determined for the first time. Hexadecanoic acid (13.3-21.2% and 48.1-59.8%) was the main component of the samples of G. cornutum and G. confertum, respectively, while caryophyllene oxide (13.1-29.2%) was the major constituent in the samples of G. macrodon subsp. nezaketae and G. macrodon subsp. macrodon as well as γ-terpinene (61.9%) and carvacrol (68.9%) in G. daucoides samples. In addition, pentacosane can be considered a chemotaxonomic marker for the essential oil of G. macrodon subsp. macrodon.

Abstract: Volatile constituents obtained from crushed fruits and aerial parts of Grammosciadium pterocarpum Boiss. (Apiaceae) by microdistillation were analyzed by gas chromatography (GC) and GC–mass spectrometry (GC–MS) systems, simultaneously. Fifteen components comprising 99.5% of the volatile oil of the fruit and twenty components comprising 97.4% of the volatile oil of the aerial parts were identified. The main
constituents of the fruit volatiles were found to be linalool (68.4%) and β-pinene (22.0%), whereas caryophyllene oxide (55.1%) and β-caryophyllene (15.3%) were found to be major constituents in the volatiles of the aerial parts.
In this study, the Artemisia santonicum L.(facultative halophyte plant) community and soil peculiarity of Ereğli-Karaman had been analyzed based on the minimal area approach. Of the samples collected from the research area between the years 1995-1996 and 2012-2013, 100 plants were evaluated, and uncommon and endemic taxa were identified. The number of endemic taxa within the study area is 15. The study area is located in the southeast of Central Anatolia covered with alkaline soils. The Artemisia santonicum community is under the control of very cold and arid Mediterranean climate. Relations between the ecologial properties (such as soil properties and climate) and plant cover are examined. Based on the results of floral biodiversity and ecological properties were discussed. Results showed that, on the distribution of vegetation are important factors, respectively; climatic, edaphic, anthropogenic. In terms of biodiversity conservation of these areas it is very important furthermore the protection of these areas showed that very necessary.
... It is widely recognized that overgrazing is a primary factor in vegetation degradation in Central Anatolia (Ünal and Fırıncıoğlu 2007;Gökbulak et al. 2018). In his region, grazing significantly reduces the cover of forbs and grasses (Fırıncıoğlu et al. 2009(Fırıncıoğlu et al. , 2010, with forbs experiencing the most substantial negative impact (Fırıncıoğlu, Seefeldt, and Şahin 2007). However, the cover of cushion-type subshrubs appears similar in both grazed and ungrazed areas (Fırıncıoğlu et al. 2010). ...
... As noted above, the fruit shattering in Arabidopsis requires the differentiation of an intricate DZ along the valve margins (Ballester and Ferrándiz 2017). Comparative anatomical analysis shows that the organisation of DZ structures is largely conserved in dehiscent fruit species (Aethionema, Brassica, Capsella, Cardamine and Lepidium), whereas its identity is partially developed or completely lost in species with an indehiscent silique/silicle (Aethionema and Lepidium) Mühlhausen et al. 2013;Lenser et al. 2016;. A close examination of the DZ patterning genes shows that the expression of the respective genes is abolished in the corresponding cells of indehiscent fruits (Mühlhausen et al. 2013;Lenser et al. 2016). ...
... The first attempt to identify the specimens of Lepyrodiclis was made using major floristic accounts (Schischkin 1936, Davis 1967, Davis et al. 1988, Rechinger 1988, Güner et al. 2000, as well as local floristic studies (Behçet 1989, Altan and Behçet 1994, Altıok and Behçet 2005, Korkmaz et al. 2008, Öztürk et al. 2015, Tel and Eğilmez 2015, Bingöl et al. 2017, Keser and Özgökçe 2019. Morphological examinations and comparisons of the specimens were made at the herbaria of GAZI, ISTE, EGE, HUB, E and G. Pictures were taken at different magnifications with a scanning electron microscope (SEM) to determine the taxonomically important pollen and seed micromorphological characters. ...
... A few isolated populations are also known in Türkiye (Kars, Hakkâri, Siirt, Muş). In Türkiye, it is still very likely places where Zelkova carpinifolia has not yet been discovered [29][30][31][32][33] . Hyrcanian forests are significant remnants of Arcto-Tertiary forests in western Eurasia 34 and are home to various thermophilous species 26,[35][36][37][38] . ...
... Here, we exploit the diaspore dimorphism of Aethionema arabicum (Figure 1), an annual member of the earliest diverging sister tribe within the Brassicaceae, in which seed and fruit dimorphism was associated with a switch to an annual life history (Lenser et al., 2016;Mohammadin et al., 2017;Chandler et al., 2024). Ae. arabicum is adapted to arid and semiarid environments, its lifehistory strategy appears to be a blend of bet-hedging and phenotypic plasticity (Bhattacharya et al., 2019b), and it exhibits true seed and fruit dimorphism with no intermediate morphs (Lenser et al., 2016). ...
... Additionally caryophyllene oxide (11.4%) was determined as main compound of the essential oil of SP. These results indicate that chemical constituents in the essential oils and the amounts of the major compounds showed difference, according to the geographical location, season, climatological variations, plant variety and experimental conditions investigated parts of the plants [17][18][19][20]. ...
... Anatolia, some of these studies were carried out by Birand (1947, 1970), Çetik et al. (1981, 1985), Yurdakulol (1974), Akman et al. (1984, 1985, 1996), Ocakverdi et al. (1991), Tatlı et al. (1994) and Geven et al. (2009, 2010). In this study, the Artemisia community and ecological characteristics of ...
... Effectively germinating seeds are an excellent source of material for the initiation of in vitro culture aimed at the mass vegetative propagation of species exhibiting unique features. Such an approach was previously reported for different metallophytes like Alyssum corsicum [40], Gypsophila fastigiata [5], or Viola arvensis [6]. Similarly, seeds of Alyssum murale, A. alyssoides, and A. montanum were used to determine the composition of the growth medium for successful plant regeneration and multiplication. ...
... The aerial parts alkaloid extracts of Sophora alopecuroides L. var. alopecuroides presented antibacterial ability against Bacillus subtilis and Staphylococcus aureus with MICs of 62.5 mg/mL, corresponding to 0.02 mg/mL and 0.08 mg/mL ciprofloxacin, and the seeds alkaloid extracts performed antifungal capacity against Candida krusei (MIC = 25.00 mg/mL) as equal effect to 1.75 mg/mL fluconazole (Kucukboyac et al., 2011). ...
... During field investigations within 2010 and 2012, we collected unknown samples of Dichoropetalum in Yenişarbademli, Dedegöl Mountains (Isparta, south-western Turkey), which did not match any previously described species. After thorough investigation of relevant literature (Korovin 1951, Zohary 1966, Chamberlain 1972, Rechinger 1987, Pimenov 1987, Davis et al. 1988, Pimenov & Leonov 1993, Güner et al. 2000, Parolly & Nordt 2004-2005, Adıgüzel et al. 2011, Pimenov & Kljuykov 2011, Akpulat & Akalın 2010 and comparisons with specimens from the herbaria GAZI, ANK and HUB (acronyms according to Thiers 2016), we conclude that samples from Yenişarbademli belong to an undescribed species which is named below D. vuralii. ...
