10 گونه با 12 جمعیت از خانواده‌های مختلف بومی ایران مورد بررسی قرار گرفتند. بررسب عدد کروموزومی گیاهان کمک شایانی در بدست آوردن اطلاعات تکاملی آنها می نماید.هدف از این بررسی بدست آوردن عدد کروموزومی گونه‌ها و جمعیت‌های مختلف گیاهان بود. بذر گونه ها از مناطق مختلف ایران جمع آوری گردید. دو گونه Melica persica و Silene vulgaris دارای دو جمعیت است. عدد کروموزومی Papaver rhoeas (14=n2) و Filipendula...
The Romanian hamster Mesocricetus newtoni is endemic to South-Eastern Romania (Dobruja region) and North-Eastern Bulgaria, prefers steppic, arid, uncultivated habitats, but also found in alfalfa fields, less often corn cultures field-protecting vegetation belts. Previous studies provide only limited data regarding the diet of this cryptic species. one family group (one female four pups) was mon...
A field experiment was established to evaluate quantitative changes in weed species prevailing a crop rotation and 30-year cereal monoculture. The subject of the study included cropping systems: a) rotation, b) First (1989–1992) second (1993–1996) focused on infestation winter triticale monoculture; third (1997–2000) fourth (2001–2004) wheat; fifth (2005–2008), sixth (2009–2012), seventh (2013–...
BACKGROUND Clinical practice guidelines have traditionally recommended blood pressure treatment based primarily on blood pressure thresholds. In contrast, using predicted cardiovascular risk has been advocated as a more effective strategy to guide treatment decisions for cardiovascular disease (CVD) prevention. We aimed to compare outcomes from a blood pressure-lowering treatment strategy based...
The integration of signals received by a cell, and their transduction to targets, is essential for all cellular responses. The cytoskeleton has been identified as a major target of signalling cascades in both animal and plant cells. Self-incompatibility (SI) in Papaver rhoeas involves an allele-specific recognition between stigmatic S-proteins and pollen, resulting in the inhibition of incompat...
