مطالعه خصوصیات بومشناختی گونه Ferula ovina Boiss با هدف شناخت و دستیابی به اطلاعات کاربردی و استفاده از آن در برنامههای اصلاح و توسعه مراتع انجام شد. برای این منظور ابتدا به کمک نقشه پوشش گیاهی و بازدید میدانی اقدام به تهیه نقشه رویشگاه این گونه گردید. سپس سه منطقه مختلف شامل سیرچ، مدیم و حتکن به عنوان ایستگاههای مطالعاتی انتخاب شد. نمونهبرداری در هر یک از ایستگاهها با روش سیستماتیک تصادف...
Xinjiang, a region of high salinity and drought, is a host to many arid and semi-arid plants. Many of these plants including Ferula spp. have indigenous pharmaceutical histories. As many of the medicinal properties of plants are in tandem with the associated microorganisms residing within the plant tissues, it is advisable to explore the endophytic potential of such plants. In the present study...
Twelve microsatellite loci were developed from Haliotis ovina by the magnetic bead hybridization method. Genetic variability was assessed using 30 individuals from 3 wild populations. The number of alleles per locus ranged from 2 to 5, and the polymorphism information content ranged from 0.1228 to 0.6542. Observed and expected heterozygosities ranged from 0.0000 to 0.7778 and 0.1288 to 0.6310, ...
Ferula turcica and latialata are two novel endemic species discovered in the Konya Kırşehir provinces of central Anatolian region Türkiye. These new described by morphological, ecological, carpological, phytochemical characteristics phylogenetic analysis. F. morphologically distinct from szowitsiana their habit, stalk terminal umbella, mericarp size, as well profile secondary metabolite markers...
Neuroinflammation mediated by microglia cells plays a critical role in the development of Alzheimer's disease. To identify novel natural neuroinflammation inhibitors, a bioactivity-guided phytochemical research was performed on the traditional Chinese medicine "Awei", that exhibited a significant inhibitory effect on nitric oxide production in over-activated microglia cells. The research identi...
BACKGROUND A horizontal gene transfer has brought an active nuclear gene, PgiC2, from a polyploid Poa species (P. palustris or a close relative) into the common grass sheep's fescue (Festuca ovina). The donor and the receptor species are strictly reproductively separated, and PgiC2 occurs in a polymorphic state within F. ovina. The active gene copy is normally closely linked to a very similar p...
BACKGROUND Medicinal plants are considered new resources for producing agents that could act as alternatives to antibiotics in the treatment of antibiotic-resistant bacteria. The aim of this study was to evaluate the antibacterial activity of 28 plant extracts and oils against four Gram-negative bacterial species. METHODS Experimental, in vitro, evaluation of the activities of 28 plant extrac...
Studies of whether plant community structure and ecosystem properties depend on the genetic diversity of component populations have been largely restricted to species monocultures and have involved levels of genetic differentiation that do not necessarily correspond to that exhibited by neighboring mature individuals in the field. We established experimental communities of varying intraspecific...
در این مطالعه توانایی مدل رگرسیون افزایشی تعمیمیافته در تهیه نقشه رویشگاه بالقوه گونه گیاهی کما (Ferula ovinaBoiss) و ترسیم منحنیهای عکسالعمل گونه نسبت به متغیرهای محیطی در منطقه فریدون شهر واقع در غرب اصفهان با مساحت هزار کیلومترمربع بررسی شد. دادههای حضوروغیاب F. ovina به روش تصادفی طبقهبندی شده از تعداد دویست و هفتادوهشت سایت (یکصد و سیوهشت سایت حضور و یکصد و چهل سایت غیاب) جمعآوری ...
