Seeds of understanding of plant diversity.
F orests, grasslands, and other plant communities often contain large numbers of plant species; in the extreme, over a thousand tree species may be present in a single square kilometer of tropical forest (1). Ecologists have long sought to understand what factors govern the array of plant species present in any particular area, and indeed, how so many species can coexist at all given that all p...
متن کاملextraction and characterization of allium irancum plant extract and its application in the green synthesis of silver nano particles and oxidation of thiocarbony1 compounds
سنتز سبز نانوذرات فلزی (nps) درسالهای اخیر توجه بسیارزیادی را به خود جلب کرده است. زیرا این پروتوکل کم هزینه وسازگار با محیط زیست از روش های استاندارد سنتز. در این پایان نامه ما گزارش میکنیم یک روش ساده و سازگار با محیط زیست برای سنتز نانوذرات نقره با استفاده از محلول آبی عصاره گیاه allium iranicum به عنوان یک عامل کاهش دهنده ی طبیعی. نانو ذرات نقره مشخص شد با استفاده از تکنیک های uv-visible، x...
Antiproliferative constituents in the plant 8. Seeds of Rhynchosia volubilis.
The MeOH extract of the seeds of Rhynchosia volubilis (Leguminosae) showed antiproliferative activity against human gastric adenocarcinoma [MK-1, 50% growth inhibition (GI50): 25 microg/ml], human uterus carcinoma (HeLa, GI50: 30 microg/ml), and murine melanoma (B16F10, GI50: 8 microg/ml) cells. Bioactivity-guided fractionation resulted in the isolation of gallic acid methylester (1), gallic ac...
متن کاملSowing the seeds of dialogue: public engagement through plant science.
With enhanced public accessibility of scientific information, increased demand for a scientifically literate workforce and citizenry, stipulations from funding agencies to broaden the impact of science research, and changing rewards systems at universities, scientists are looking for ways to engage the public in their work. This commentary is designed to share our philosophy of engaging the pub...
متن کاملPI(3,5)P2 sows the seeds of plant growth
I n all eukaryotes, formin proteins nu-cleate and elongate actin fi laments using conserved " formin homology " domains called FH1 and FH2. Many fungal and animal formins are regulated by Rho GTPases, but plant formins lack N-terminal Rho-binding domains (1). van Gisbergen et al. reveal that certain formins in the moss Physcomitrella patens are regulated instead by the phospholipid PI(3,5)P 2 (...
