In current studies, registration, genetic identification and protection of especially endemic plant species are carried out by DNA barcoding techniques. Molecular studies are based on the amplification and sequencing of the barcode gene regions by the PCR method. Campanula choruhensis Kit Tan & Sorger is endemic and widespread in Artvin and around Çoruh valley passing through it. Roots of this species are used in medicinal and aromatic studies. Intense roadworks and dam constructions are carried out in and around the distribution area of this species. This situation harms the habitat of the species and comes across with its extinction. In this study, the plastid barcode gene regions (trnK-rps16 and trnL-rpl32) of the C. choruhensis was sequenced from five populations. To make the identification of this species quickly and accurately, gene sequence compared with sequences of other related Campanula L. species. In addition, gene sequences (in Genbank Library) and phylogenetic relations were given.

The Çoruh River basin, nestled in the lower Caucasus in Türkiye, serves as a valuable repository of pear germplasm. To elucidate the genetic structure of pear populations in this region, 84 village pear cultivar genotypes (land races) from six villages, sample garden collections (SCC), and wild Panta root stock populations were analysed using eleven microsatellite markers. Genetic diversity and structure analyses indicated that village pear cultivar populations exhibit substantial genetic diversity and admixture. This diversity is attributed to local farming practices such as phenotypic selection and widespread dispersal of clonal materials. The genetic structure analysis, combined with the identification of private alleles, indicates that the pear genetic resources in the Çoruh river basin likely has originated from two gene pool sources, specifically the Meydancık and Camili village pear traditional cultivar populations. The Camili village pear cultivar population as a new in situ genetic reserve site has been proposed. Despite the existence an ex situ conservation site, the study suggests inadequateness of SCC as an ex situ site in capturing the full extent of genetic diversity of village pear cultivar genetic resources. Thus, enriching the genetic diversity in the SCC ex situ site is essential for effective pear genetic resource conservation in the Çoruh river basin. These findings contribute valuable insights for the development of targeted conservation strategies, ensuring the preservation of pear genetic resources in this region.

Gardens and the cultivation of plants have been around for thousands of years with the first examples dating to around 3,000 years ago in ancient Egypt and Mesopotamia. In the last 50 years botanic gardens are increasingly recognised as being extremely important to conservation due to their existing collections and the scientific knowledge they possess in the propagation of plant species. There are 3765 botanical institutions, 1775 botanic gardens and arboreta in 148 countries around the world with many more under construction or being planned. 628 of them are being members of the Botanic Gardens Conservation International (BGCI) platform. The Artvin Çoruh University Ali Nihat Gökyiğit Botanical Garden (ANGBB) was established in 2018 and opened to the public in 2022. ANGBB is one of the 13 botanical gardens from Turkey that are members of this platform. There are around 30,000 plants belonging to approximately 2000 different species, including 400 rare, 200 medicinal-aromatic, and about 1400 decorative species, cultivated in the garden. A total of 594 seeds belonging to specialized species such as Medicinal Aromatic and endemic plants are preserved in the seed house of the botanical garden. Within the scope of this research, the purpose, functions, planning, and design of botanic gardens have been evaluated according to the economic, ecological, and social components of sustainability, and sustainable planning and design criteria have been established for the ANGBB. These criteria address structural landscape design, plant landscape design, administrative planning, spatial planning, educational, social, and cultural planning, as well as management and maintenance. The ANGBB has been evaluated in terms of sustainable planning and design criteria, and recommendations for enhancing the sustainability of the ANGBB have been provided based on the data obtained.

The importance of nanotechnology has increased recently since it has effective and widespread usage areas. In this study, silver nanoparticles (AgNPs@Se) were synthesized using S. ebulus leaf extract and their structures were clarified by spectroscopic analyses including FTIR, UV–Vis, and XRD. The morphology and particle size of AgNPs@Se were determined by SEM analysis. Quantitative analysis of bioactive compounds of S. ebulus leaf extract was defined by HPLC analysis. Antioxidant activity of extract and AgNPs@Se was executed by DPPH•, ABTS•+, and FRAP assays. The antibacterial activity of AgNPs was carried out using agar well diffusion and microdilution broth methods. Quantitative analysis of bioactive compounds in S. ebulus leaf extract was established by HPLC. The average particle size of nanoparticles was calculated as 18.6 nm. Isoquercitrin was found as a major product. AgNPs@Se displayed excellent antioxidant activity, but they revealed a moderate antibacterial effect. The structure of nanoparticles was assigned as a face center cubic unit cell. Hence, nanoparticles could be a favorable agent for the pharmaceutical and food industry.

ABSTRACT
This study was carried out between 2013 and 2015 in order to determine the Flora of Tekmezar Mountain (Sarıbudak village, Artvin) and its surroundings. The research area is located in the A8 square according to Davis's grid system and is located in the Colchic sub-section of the Euxine part of the Euro-Siberian flora area of the Holarctic region. The study area is located between 300-3224 m altitudes. In the selection of the research area;
The geographical location of the area, its topographic structure and its unique climate, rich endemic and rare plants, being a transition zone between the European-Siberian and Irano-Turanian flora areas and having a rich
plant species diversity have been taken into consideration. In this study, it was aimed to determine new taxa and to determine the floristic structure of Tekmezar Mountain. In this study, a total of 363 taxa belonging to 89 families
and 254 genera were identified. Of these, 11 taxa belong to Polypodiopsida, 4 to Pinopsida, 327 to Magnoliopsida, and 22 to Liliopsida. The families that contain the most taxa in the research area are respectively; Asteraceae (45
taxa), Fabaceae (33 taxa), Rosaceae (28 taxa), Lamiaceae (25 taxa), Boraginaceae (14 taxa), Caryophyllaceae (12 taxa), Brassicaceae (11 taxa), Ranunculaceae (10 taxa), Apiaceae (10 taxa) and Plantaginaceae (9 taxa).
Phytogeographic regions of 174 taxa determined in the study area were determined. The distribution of these species by phytogeographic regions is as follows: 130 (35.6%) Euro-Siberian, 37 (10.2%) Iranian Turan and 7 (1.9%)
Mediterranean. There are 191 (52.3%) spread in the region. The distribution and proportions of taxa according to their life forms are as follows: Hemicryptophytes 109 taxa (29.9%), Cryptophytes 66 taxa (18.1%), Phanerophytes 49 taxa (13.4%), Kamephytes 48 taxa (13.2%), and Therophytes are 31 taxa (8.5%). 16 endemic and 29 non-endemic
rare plant species were detected in the research area, and the endemism rate is 3.9%. Endemic and non-endemic rare 45 taxa were evaluated according to IUCN categories.
known as Beşpare Villages of the central district of Artvin, between 2017 and 2020, as well as to determine the potential of fruit grown in the gardens. was made for the purpose. The study area has
an area of 7,000 hectares between 190-3000 m altitudes. Phytogeographically, it is located in the Colchic sub-section of the Holarctic region, the Euro-Siberian flora area, the Euxine section. As a result of the questionnaire applied to 120 people in the research area; It has been determined that 75 plant species belonging to 39 families are used by the local people for medicinal and aromatic purposes.
Using the survey results, informative consensus (FIC-Factor informant consensus), validity level (FLfidelity level) and UV-use value factor were analyzed. The families containing the most taxa used for medicinal and aromatic purposes in the research area are respectively; Rosaceae (8 taxa), Asterecaeae (5 taxa), Lamiaceae (4 taxa), Apiaceae (4 taxa).
with molecular studies recently, it has been determined that the nomenclature of these taxa has been changed in the names of genus and species throughout the world, although they are not in scientific
publications in our country. According to this data, Sorbus species in Turkey have been updated taxonomically, and as a result of recent studies, it has been observed that the genus names of some
Sorbus species have been changed. The number of genera belonging to the Rosaceae family distributed in Turkey; While it increased from 35 to 38 with the newly added Aria (4 species), Sorbus (2 species), Torminalis (1 species) and Hedlundia (7 species), the number of species decreased by 3 due to the synonymous situation. In this study, Sorbus species in Turkey have been updated taxonomically, genus and species identification keys as well as photos of the species are given
and Boraginaceae 26. The floristic regions of 331 taxa (43.10%) determined in the study area were determined. The distribution of taxa according to phytogeographical regions is as follows: 163 (21.20%) Iran-Turanian, 95 (12.40%) are Europe-Siberia, 26 (3.40%)
Mediterranean origin, 47 (6.10%) cosmopolitan. 82 endemic plants have been identified in the research area, and the endemism rate is 10.67%. Endemic and non-endemic plants are classified according to IUCN hazard categories.
ABSTRACT
This research was conducted to determine the flora of Erzurum marshes in Yakutiye district, Erzurum province between 2017-2019. As a result of the naming of 885 plant specimens collected from the
research area, a total of 223 plant taxa belonging to 141 genera belonging to 40 families were found to show natural spread in the area. Of the taxa identified, 33 belong to the liliopsida and 190 belong
to the Magnoliopdisa classes. Asteraceae (44), Fabaceae (20), Lamiaceae (17), Poaceae (12) and Caryophyllaceae (11) are the richest families in terms of total number of taxa. The genera containing
the most species are Achillea (5), Astragalus (5), Silene (4), Centaurea (4). The distribution of phytogeographic elements is as follows: Europe-Siberia 32 (14.0%), Iran-Turan 63 (28.1%) and multior unknown region 128 (57.9%). 25 endemic plant species have been identified in the area, with an endemism rate of 11.2%. The endangered status of 29 taxa, endemic and non-endemic, has been assessed according to the IUCN Red List Categories.
In this study, general morphological characteristics, the leaf and wood anatomical characteristics and, leaf micromorphological features of Rhamnus microcarpa, which is native in Artvin were investigated in detail. Leaves broadly ovate, 3.0-5.5 x 1.9-3.9 cm; stipules 4-7 mm; pinnately 7-10 veined; petiol 615 mm. Bud scales dark brown transverse band at the base. Wood was semi-ring porous to ring porous, rays heterocellular, fibers thick-walled especially in latewood. In leaves, dorsiventral mesophyll, hypostomatic type stomata and simple unicellular trichomes observed. Also, epicuticle scales in the lower leaf surface observed.

Bitkiler eski çağlardan beri tıbbi amaçlarla kullanılmaktadır. İçerdikleri biyoaktif sekonder metabolitlerden dolayı, bitkiler ilaç keşfi ve gelişimi için oldukça fazla ilgi görmektedir. Bu çalışmada, Galanthus woronowii türüne ait bitki materyalleri sırasıyla hekzan, diklorometan ve etil asetat ile ekstrakte edilmiştir. Çözücü dönerli buharlaştırıcı ile uzaklaştırıldıktan sonra ham ekstraktlar elde edilmiştir. Ekstraktların DPPH serbest radikal giderme, ABTS radikal katyon giderme ve indirgeme gücü aktiviteleri değerlendirilmiştir. Ayrıca toplan fenolik içerik belirlenmiştir. Etil asetat ekstraktının en çok fenolik içerdiği ve en yüksek antioksidan aktivite gösterdiği belirlenmiştir. Bu nedenlerle, bu bitki ümit verici antioksidan ajan olarak kabul edilebilir.
