Travel Tales of a Worldwide Weed: Genomic Signatures of Plantago major L. Reveal Distinct Genotypic Groups With Links to Colonial Trade Routes.

Retracing pathways of historical species introductions is fundamental to understanding the factors involved in the successful colonization and spread, centuries after a species' establishment in an introduced range. Numerous plants have been introduced to regions outside their native ranges both intentionally and accidentally by European voyagers and early colonists making transoceanic journeys; however, records are scarce to document this. We use genotyping-by-sequencing and genotype-likelihood methods on the selfing, global weed, Plantago major, collected from 50 populations worldwide to investigate how patterns of genomic diversity are distributed among populations of this global weed. Although genomic differentiation among populations is found to be low, we identify six unique genotype groups showing very little sign of admixture and low degree of outcrossing among them. We show that genotype groups are latitudinally restricted, and that more than one successful genotype colonized and spread into the introduced ranges. With the exception of New Zealand, only one genotype group is present in the Southern Hemisphere. Three of the most prevalent genotypes present in the native Eurasian range gave rise to introduced populations in the Americas, Africa, Australia, and New Zealand, which could lend support to the hypothesis that P. major was unknowlingly dispersed by early European colonists. Dispersal of multiple successful genotypes is a likely reason for success. Genomic signatures and phylogeographic methods can provide new perspectives on the drivers behind the historic introductions and the successful colonization of introduced species, contributing to our understanding of the role of genomic variation for successful establishment of introduced taxa.

Ethnomedicinal Plants of Hasankeyf (Batman-Turkey).

Hasankeyf is an ancient city, dating back to more than 10,000 years, in the Southeast Anatolia Region of Turkey. The area is separated by the Tigris River on both sides and located in the Batman province. However, as a result of a dam project, in February 2020, this ancient city and some of its surrounding villages were totally flooded. The residents were moved to new settlements. This study aimed to prevent the possible loss of ethnomedicinal knowledge of plants due to migration as well as to pass on this knowledge to the future generations. The field studies were conducted between March 2017 and November 2019 in the city center and 22 rural settlements of Hasankeyf. Also, the areas where intensive migration was experienced were visited frequently. Interviews were conducted with a total of 131 participants (76 women and 55 men) while gathering plants with them. Information was collected through interviews and questionnaires. The results were analyzed by quantitative indices of information consensus factor (FIC) and use value (UV). A total of 94 plant taxa belonging to 40 families were identified in the study area. The most common medicinal plant families are Lamiaceae (13), Asteraceae (8), Rosaceae (6), Malvaceae (6), Amaryllidaceae (5), Brassicaceae (4), and Solanaceae (4). The most common preparations were infusion, fresh application, and crushing. The taxa having the highest count of use value (UV) were Teucrium polium, Matricaria aurea, Urtica dioica, Mentha longifolia, and Quercus brantii. Besides, the recorded ailments were grouped into categories based on information provided by the interviewees. The most important use categories among the informants were diabetes, gastrointestinal disorders, respiratory disorders, and dermatological disorders. The present study represents the first medical-ethnobotanical documentation and analysis of the traditional use of medicinal plants in Hasankeyf.

Taming the pandemic? The importance of homemade plant-based foods and beverages as community responses to COVID-19.

Household responses to COVID-19 in different corners of the world represent the primary health care that communities have relied on for preventing and mitigating symptoms. During a very complex and confusing time, in which public health services in multiple countries have been completely overwhelmed, and in some cases even collapsed, these first-line household responses have been quintessential for building physical, mental, and social resilience, and for improving individual and community health. This editorial discusses the outcomes of a rapid-response preliminary survey during the first phase of the pandemic among social and community contacts in five metropolises heavily affected by the COVID-19 health crisis (Wuhan, Milan, Madrid, New York, and Rio de Janeiro), and in twelve rural areas or countries initially less affected by the pandemic (Appalachia, Jamaica, Bolivia, Romania, Belarus, Lithuania, Poland, Georgia, Turkey, Pakistan, Cambodia, and South Africa). We summarized our perspectives as 17 case studies, observing that people have relied primarily on teas and spices ("food-medicines") and that there exist clear international plant favorites, popularized by various new media. Urban diasporas and rural households seem to have repurposed homemade plant-based remedies that they use in normal times for treating the flu and other respiratory symptoms or that they simply consider healthy foods. The most remarkable shift in many areas has been the increased consumption of ginger and garlic, followed by onion, turmeric, and lemon. Our preliminary inventory of food medicines serves as a baseline for future systematic ethnobotanical studies and aims to inspire in-depth research on how use patterns of plant-based foods and beverages, both "traditional" and "new", are changing during and after the COVID-19 pandemic. Our reflections in this editorial call attention to the importance of ethnobiology, ethnomedicine, and ethnogastronomy research into domestic health care strategies for improving community health.

Wild edible plants in Yesilli (Mardin-Turkey), a multicultural area.

BACKGROUND: The Yesilli district (Mardin) is located in the southeastern of Turkey and hosts different cultures. The objective of this study was to record the traditional knowledge of wild edible plants used by indigenous people in Yesilli, where no ethnobotanical studies have been conducted previously. METHODS: An ethnobotanical study was carried out in Yesilli district in March 2017-March 2019 to document the traditional knowledge of wild edible plants. The data were collected by interviewing 62 informants. Additionally, the data were analysed based on the cultural importance index (CI) and factor informant consensus (FIC) to determine the cultural significance of wild edible plants and knowledge of wild edible plants among the informants. RESULTS: We documented 74 wild edible taxa belonging to 31 families and 57 genera in the present study. The richness of the wild edible taxa was highest for vegetables (46 taxa), followed by medicinal plants (17 taxa) and fruit (14 taxa). The most important families were Asteraceae (ten taxa), Rosaceae (seven taxa) and Fabaceae (six taxa). The most culturally important taxa (based on the CI index) were Ficus carica subsp. carica, Lepidium draba, Anchusa strigosa, Rhus coriaria, Glycyrrhiza glabra, Sinapis alba, Gundelia tournefortii, Notobasis syriaca, Onopordum carduchorum, Malva neglecta, Mentha longifolia, Juglans regia and Urtica dioica. The maximum number of use reports was recorded for vegetables (1011). The factor informant consensus index (Fic) varied between 0.95 and 0.98 for preserved vegetables, beverages and spices and processed fruits have the highest Fic (0.99). We reported for the first time the ethnobotanical usage of 12 taxa as food. We also recorded the use of Allium wendelboanum, an endemic species in the study area. CONCLUSION: The obtained data were compared with data from other wild edible and ethnobotanical studies conducted in Turkey and particularly those conducted in eastern Turkey. Furthermore, the data were compared with data from studies conducted in the bordering countries of Iraq and Armenia. The present study reflects the cultural diversity of the region, and it is necessary to conduct more studies since it is thought that this diversity will contribute to the economy. This study will enable the traditional use of wild plants as food sources to be passed on to future generations.

Essential oil compositions and anticholinesterase activities of two edible plants Tragopogon latifolius var. angustifolius and Lycopsis orientalis.

This is the first report in the literature on essential oil compositions of Tragopogon latifolius var. angustifolius and Lycopsis orientalis which were analysed by using GC-FID and GC-MS techniques. The main constituents of T. latifolius var. angustifolius were identified as α-selinene (10.5%), 2,5-di-tert octyl-p-benzoquinone (9.5%) and valencene (7.0%); however, the main components of L. orientalis were identified as heptacosane (10.5%), τ-muurolene (9.6%) and tetratetracontane (9.4%). The essential oils of T. latifolius var. angustifolius and L. orientalis species exhibited moderate inhibitory activity against acetyl- and butyryl-cholinesterase enzymes at 200 µg/mL.

Chemical compositions by using LC-MS/MS and GC-MS and biological activities of Sedum sediforme (Jacq.) Pau.

In this research, the chemical composition and biological activities of various extracts obtained from whole parts of Sedum sediforme (Jacq.) Pau were compared. The amounts of total phenolic and flavonoid components in crude extracts were determined by expression as pyrocatechol and quercetin equivalents, respectively. All of the extracts (petroleum ether, acetone, methanol, and water) obtained from S. sediforme showed strong antioxidant activity in four tested methods. Particularly, the IC50 values of the methanol extract, which was the richest in terms of total phenolic and flavonoid contents, were found to be lower than those of α-tocopherol and BHT in ß-carotene bleaching (9.78 ± 0.06 µg/mL), DPPH free radical scavenging (9.07 ± 0.07 µg/mL), and ABTS cation radical scavenging (5.87 ± 0.03 µg/mL) methods. Furthermore, the methanol extract of S. sediforme showed higher inhibition activity than galanthamine against acetyl- and butyryl-cholinesterase enzymes. Also, acetone and methanol extracts exhibited moderate antimicrobial activity against Candida albicans. The main constituents of fatty acid and essential oil were identified as palmitic acid (C16:0) (28.8%) and α-selinene (20.4%), respectively, by GC-MS. In the methanol extract of S. sediforme, quercetin, rutin, naringenin, and protocatechuic, p-coumaric, caffeic, and chlorogenic acids were detected and quantified by LC-MS/MS. Results of the current study showed that the methanol extract of S. sediforme may also be used as a food supplement.
