In this study, 45 Pleurotus isolates with a wide range of geographical origins (in five provinces of Iran: Isfahan, Chaharmahal Bakhtiary, Kohkiloye boyrahmad, Lorestan and Fars) were collected. A random amplified polymorphic DNA polymerase chain reaction (RAPD-PCR) was used to assess the genetic diversity in ten populations of the Pleurotus eryngii complex. The use of ten primers allowed the p...
The dimeric metabolic enzyme phosphoglucose isomerase (PGI, EC 5.3.1.9) plays an essential role in energy production. In the grass Festuca ovina, field surveys of enzyme variation suggest that genetic variation at cytosolic PGI (PGIC) may be adaptively important. In the present study, we investigated the molecular basis of the potential adaptive significance of PGIC in F. ovina by analyzing cDN...
This study was aimed to predict the potential distribution of Ferula ovina (Boiss) in Feridoonshar, in the western part of Isfahan province, and to produce species response curves in relation to the environmental variables using the Generalized Linear Model (GLM). The presence and absence of the species in 278 sites (including 138 presence sites & 140 absence sites) were collected using random ...
Objective: This study is to investigate the antioxidant and antitumor effects of the extract fractions of the Ferula sinkiangensis K. M. Shen. Methods: Four different fractions of the Ferula sinkiangensis K. M. Shen were obtained by the extraction with petroleum ether, ethyl acetate, n-butanol, and methanol, respectively, which were used to treat the HCT116, Caco-2, HepG2, and MFC cells. Free r...
هدف از این مطالعه بررسی توانایی مدل آماری شبکه عصبی مصنوعی در تهیه نقشه رویشگاه بالقوه گونه علوفه ای و دارویی ferula ovina boissدر مراتع منطقه فریدونشهر اصفهان می باشد. به منظور تعیین رویشگاه بالقوه گونه f. ovina (کما)، از داده های محیطی به عنوان متغیر مستقل و داده های مربوط به رخداد گونه کما به عنوان متغیر وابسته استفاده گردید. نقشه پراکنش مکانی عوامل محیطی از قبیل خصوصیات توپوگرافی (ارتفاع از...
به دلیل عدم کفایت اطلاعات در مورد پراکنش گونه های گیاهی و جانوری، استفاده از مدل سازی برای پیش بینی پراکنش گونه ها در سال های اخیر افزایش یافته است. به این منظور طیف گسترده ای از تکنیک های مدل سازی ابداع شده است. در پژوهش حاضر با استفاده از عوامل محیطی و داده های رخداد گونه کما (ferula ovina boiss.) و با بکارگیری مدل ژنتیک الگوریتم نقشه پراکنش این گونه تهیه شد. داده های رخداد گونه (137 سایت) با...
variability in morphological traits, phenolic content, and antioxidant activity of 15 populations of iranian ferula species collected from natural habitats in different regions of iran were investigated. total phenolic content (tpc) of fruit extracts varied from 12.77 to 120.72 mg tannic acid per 1g dry weight. total flavonoid of fruits extract varied from 5.45 mg quercetin per 1 g dry weight i...

Species distribution maps have been widely developed based on ecological niche theory together with statistical and geographical information system in plant ecology. The current study aimed to evaluate Artificial Neural Network (ANN) in mapping potential habitat of Ferula ovina Boiss in Ferydunshar rangelands, Isfahan. This is known as valuable forage and medicinal species. Environmental data (...
