The actin cytoskeleton is a key target for signaling networks and plays a central role in translating signals into cellular responses in eukaryotic cells. Self-incompatibility (SI) is an important mechanism responsible for preventing self-fertilization. The SI system of Papaver rhoeas pollen involves a Ca(2+)-dependent signaling network, including massive actin depolymerization as one of the ea...
Recently, the NADPH-dependent short-chain dehydrogenase/reductase (SDR) salutaridine reductase (E.C. 1.1.1.248) implicated in morphine biosynthesis was cloned from Papaver somniferum. In this report, a homology model of the Papaver bracteatum homolog was created based on the x-ray structure of human carbonyl reductase 1. The model shows the typical alpha/beta-folding pattern of SDRs, including ...
Papaver Rhoeas L. Hydroalcoholic Extract Exacerbates Forced Swimming Test-Induced Depression in Mice
INTRODUCTION Depression is one of the most frequent psychiatric disorders in the world with occurs with higher incidence in women. In the present study, the effect of water-alcoholic extract of Papaver rhoeas L. on forced swimming test (FST) in Swiss-Webster mice were examined. METHODS We used Swiss-Webster mice (20-25 g) to execute FST on them. The plant extract (1, 10, 30, and 100 mg/kg) wa...
DRUG ADDIcTIoN, especially through the use of poppy (Papaver somniferum Linn.) and hemp (Cannabis sativa Linn.), is the main concern of this paper. Although the use of these two plants in medieval Islam was extensive, yet little has been written on this timely subject by historians of medicine and pharmacology. Consulting contemporary original sources, it is my hope to sketch a history of their...
1 An experiment was carried out to test the hypotheses that in heterogeneous environments: (i) the size of species’ root systems will be negatively correlated with their ability to place roots precisely in nutrient-rich patches; (ii) precision of root placement will be less affected by distance to nutrient patches in species with large root systems; (iii) species with greater precision in root ...
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...
