Ülkemizde ise 135 familyaya ait yaklaşık 10.000 çiçekli bitki tespit edilmiştir. Bu bitkilerin yaklaşık olarak %32'si endemiktir. Günümüzde tıbbi ve aromatik bitkilerin önemi her geçen gün artmakta ve buna paralel olarak ticret hacmi de genişlemektedir. Parfümeri ve eczacılık gibi alanlarda kullanılan ada çayı hem herba olarak hem de uçucu yağ olarak ticareti yapılan önemli ürünlerden biridir. Türkiye'de 2022 yılında 12.781 dekar alanda 2.356 ton adaçayı yetiştirilmiştir. 2022 yılında 2.434 ton adaçayı ihracatından 8.489.836 dolar, 278 kg ada çayı yağından 5.354 dolar gelir elde edilmiştir. 1.138 ton ada çayı ve 1.144 kg ada çayı yağı ithal edilmiş bunun için 3.080.157 dolar harcama gerçekleşmiştir. Türkiye'nin Yukarı Fırat bölümünde 15 tanesi endemik 38 adaçayı (Salvia) türü doğal yayılış göstermektedir. Tunceli'de ise 6'sı endemik 26 adaçayı türünün doğal yayılışı vardır. İklimsel ve toprak özellikleri ile ada çayı yetiştiriciliği için Tunceli uygun şartları bulundurmaktadır.

Pollen morphology of 20 species of the Veronica were investigated using Light Microscope (LM) and Scanning Electron Microscope (SEM). Different palyno-morphological features including; pollen ornamentation, colpus ornamentation, size of polar and equatorial diameter, P/E ratio, exine thickness, and size of colpus were observed. The study revealed that the pollen grains of the studied Veronica species were in all cases tricolpate, radially symmetrical and isopolar, oblate-spheroidal or prolate spheroidal. The surface pattern of the exine varied from striato-reticulate and striato-microreticulate to microechinate-perforate, which allows recognition of three homonymous types of pollen grains.

Bugün bilim, kuraklığa ve çoraklaşmaya töleransı yüksek, potansiyel hayvan yemi olabilecek ve meraların iyileştirilmesinde kullanılabilecek bitkiler üzerinde çalışmalar yürütmektedir. Kurak bir iklime sahip Karapınar (Konya)'da yürütülen küçükbaş hayvancılık bu durumdan en fazla etkilenecek yerlerdendir. Bu çalışmayla Karapınar ve çevresinde meraların iyileştirilmesinde yararlanılabilecek bölgesel türlerin ve potansiyellerinin tespit edilmesi amaçlanmıştır. Yapılan arazi çalışmaları ile yaygın olan 13 tuzcul bitki tespit edilmiş ve bunların yem bitkisi ya da mera iyileştirmesindeki potansiyelleri değerlendirilmiştir. Mera ıslah çalışmalarında kullanılan Atriplex canescens ile aynı aileden 9 türün Karapınar'da bulunduğu, bunlardan özellikle Salicornia perennans'ın hayvan yemi, Camphorosma monspeliaca ve Bassia prostrata'nın ise mera ıslahında kullanılabileceği önerilmiştir.

The seeds of Acanthophyllum were characterised by oblong or obovate shape. Seeds dorsal and ventral side are generally convex. The largest seeds are found in A. acerosum (2.45 mm in length and 1.16 mm in width). The smallest seeds are found in A. verticillatum (1.61 mm in length and 0.84 mm in width). Seeds surface of Acanthophyllum species are fine tuberculate arranged with elongate or polygonal cells like jigsaw puzzle. The shape of suture is sinuous, undulate or dentate. The colour of seed is reddish-brown or yellowish-brown. The radicle is on the one side of each seed and just out beyond the hilar notch. Colour of seeds, seed length and width, hilum length and width, suture shape, testa cell shape and the number of suture points per plate are important characters in differentiating Acanthophyllum species. By this study, similarities and differences between the species of Acanthophyllum genus are revealed and contributed to taxonomic studies.

No hornwort taxa could be detected and only 7 taxa liverwort belong to 5 genera were collected from the area. Factors affecting the low number of liverworts can be listed as limited habitat diversity, poor water resources, high ultraviolet, rapid evaporation and poor vegetation. Mosses are represented by 168 taxa in 67 genera belonging to 17 families. Pottiaceae, Brachytheciaceae, Orthotrichaceae, Grimmiaceae, and Bryaceae which have more than ten taxa are the most species-rich families in the research area. These families, which mostly contain xerophilous taxa, are compatible with the climate of the region. Taxa, such as Asterella saccata and Orthotrichum cupulatum var. fuscum which were recently given as new records for Turkey from the research area, reveal the bryophyte diversity potential of the region.

It includes ca. 300 herbaceous species and mostly grows in Eurasia. Nepeta is represented in Turkey by 40 taxa and of these 16 are endemic. Nepeta species are commonly utilized in traditional medicine by the local people, primarily as spasmolytic, diuretic, and bronchodilator agents. As a consequence of studies on Nepeta taxa, terpenoids and flavonoids have been identified as the most common components. In this report, chemical contents of two endemic Nepeta taxa (N. viscida from Buharkent/Aydın and N. nuda L. subsp. lydiae from Altınyayla/Burdur) were presented. The main constituents were determined as α-terpineol (20.59%), trans-β-caryophyllene (9.90%) and spathulenol (9.37%) for N. viscida, and 1,8-cineole (31.31%), borneol (18.95%) and caryophyllene oxide (14.59%) for N. nuda subsp. lydiae.

However, the COVID-19 pandemic can have adverse effects on patients with epilepsy (PWE) and affect the mental health of the community in general. This study aimed to evaluate the depression and anxiety of epilepsy patients, the effect of the epidemic on the frequency of seizures, and the quality of life of the patients in the past 3 months during the pandemic. Methods: The patients who were referred to an epilepsy outpatient clinic of a tertiary neuropsychiatry center within the past 2 years were retrospectively evaluated. The data regarding the seizures, quality of life, anxiety, and depression were recorded during follow-up or through an online platform. Seizure frequency, frequency change during the pandemic (April 2020 to June 2020), medications, admissions were obtained, and Beck Depression and Anxiety Scale were applied to the patients. The patients' quality of life was evaluated using the "Quality of Life Scale Short Form-36 (SF-36)" form. Results: One hundred sixty-four patients (77 men, 87 women) included in the study were analyzed. The median overall seizure frequency and seizure frequency during pandemic were 0.2 seizures/month (0-1) and 0 seizures/month (0-0.9), respectively. 125(76.2%) of the patients reported that they had no seizures during that period. No significant difference was found between the frequency of seizures reported by the patients before and during the pandemic period (p=0.12). Only one patient had a PCR confirmed COVID-19 diagnosis, and the other six patients were diagnosed clinically and radiologically. No significant relationship was found between COVID-19 diagnosis and seizure frequency (p=0.671). 105(64.02%) patients were considered to have depressive symptoms with ten or more points according to the Beck Depression Scale. 116 patients (70.7%) were considered to have anxiety symptoms with nine or more points from the Beck Anxiety Scale. Conclusion: This study was conducted to evaluate the seizure frequency, psychiatric status, and quality of life of PWE in April, May, and June 2020 during the first peak of the COVID-19 pandemic in our country while the social restrictions were applied at the highest level. We found that there was no significant increase in the seizure frequency of patients during the pandemic period and depressive symptoms were common in this patient group and affected their quality of life.
