Background and Aims: Trichomonas vaginalis is a flagellated protozoa that is associated with vaginitis, cervicitis, urethritis and other vaginal disorders. Current study aimed to evaluate the anti-Trichomonas activity of Medicago sativa and Satureja hortensis, in vitro. Materials and Methods: Ethanolic extract of Medicago sativa and Satureja hortensis were obtained by rotary evaporator. anti-T...

تنش شوری و خشکی از مشکلات اساسی در حال افزایش جهان است که سطح وسیعی از مناطق شور و کم آب کشور ما را در بر می گیرد. با توجه به افزایش سطح اراضی شور و خشک و کمبود اراضی مطلوب در کشور، شناسایی گیاهان مرتعی مقاوم به شوری و خشکی در مرحله جوانه زنی و گیاهچه در اصلاح و احیای مراتع اهمیت زیادی دارد. به این منظور، آزمایشی در قالب طرح کاملاً تصادفی با هفت سطح شوری شامل غلظت های مشخصی از nacl (شاهد، 2، 4، ...

Saponins isolated from Medicago sativa L. appeared to stimulate lipolytic activity and did not influence amylolytic or proteolytic activity of Neopancreatinum (extract of pancreatic enzymes: lipase, proteases and amylases). Saponins isolated from the aerial part of Medicago sativa L. were demonstrated to stimulate lipase activity more effectively than saponins separated from the root of this pl...

Phosphorus (P)-deficiency is a major abiotic stress that limits legume growth in many types of soils. The relationship between Medicago and Sinorhizobium, is known to be affected by different environmental conditions. Recent reports have shown that, in combination with S. meliloti 2011, Medicago truncatula had a lower symbiotic efficiency than Medicago sativa. However, little is known about how...

We report the high-quality draft genome sequence of Xanthomonas alfalfae subsp. alfalfae strain CFBP 3836, the causal agent of bacterial leaf and stem spot in lucerne (Medicago sativa). Comparative genomics will help to decipher the mechanisms provoking disease and triggering the defense responses of this pathogen of the model legume Medicago truncatula.

Simple sequence repeat (SSR) or microsatellite DNA markers have been shown to function well in plant and mammalian species for genetic map construction and genotype identification. The objectives of the work reported here were to search GenBank for the presence of SSR-containing sequences from the genus Medicago, to assess the presence and frequency of SSR DNA in the alfalfa (Medicago sativa (L...

Poly-3-hydroxybutyrate (PHB) and glycogen are major carbon storage compounds in Sinorhizobium meliloti. The roles of PHB and glycogen in rhizobia-legume symbiosis are not fully understood. Glycogen synthase mutations were constructed by in-frame deletion (glgA1) or insertion (glgA2). These mutations were combined with a phbC mutation to make all combinations of double and triple mutants. PHB wa...

Biodiversity of the genus Medicago in Iran was studied. Distribution of two perennial species M. sativa and M. lupulina mainly conforms to the mountainous regions of Iran. Among the other annual species of this genus, M. rigidula has the most similar distribution to the distribution of perrenial species in mountainous regions. Most species of Medicago (apart from M. sativa and M. lupulina) are ...

یونجه مقادیر قابل توجهی از عناصر پتاسیم و منیزیم خاک را جذب می کند. کود دهی پتاسیم عملکرد یونجه را افزایش داده ولی تغییراتعملکرد ناشی از مصرف توام پتاسیم و منیزیم، هنوز بدرستی شناخته نشده است. فرض ما براین اساس استوار بود که روابط آنتاگونیستی پتاسیم ومنیزیم، عملکرد یونجه را تحت تاثیر قرار می دهد. هدف از تحقیق حاضر، بررسی برهم کنش پتاسیم و منیزیم بر عملکرد یونجه و اجزای عملکردبود. آزمایش به صورت...

BACKGROUND Nanotechnology has the potential to provide agriculture with new tools that may be used in the rapid detection and molecular treatment of diseases and enhancement of plant ability to absorb nutrients, among others. Data on nanoparticle toxicity in plants is largely heterogeneous with a diversity of physicochemical parameters reported, which difficult generalizations. Here a cell biol...
