Metabolism of Abscisic Acid in Guard Cells of Vicia faba L. and Commelina communis L.
Metabolism of abscisic acid (ABA) was investigated in isolated guard cells and in mesophyll tissue of Vicia faba L. and Commelina communis L. After incubation in buffer containing [G-(3)H]+/-ABA, the tissue was extracted by grinding and the metabolites separated by thin layer chromatography. Guard cells of Commelina metabolized ABA to phaseic acid (PA), dihydrophaseic acid (DPA), and alkali lab...
متن کاملLipophilic Constituents of Rumex vesicarius L. and Rumex dentatus L.
Rumex dentatus L. and Rumex vesicarius L., of the family Polygonaceae, are edible herbs growing wild in Egypt. Their lipoid constituents were examined by both liquid chromatography/mass spectrometry (LC/MS) and by gas chromatography/mass spectrometry (GC/MS). Their essential oil compositions consisted mainly of thujene, limonene, fenchon, estragole, and anethole but at largely different concent...

در این مطالعه عوامل موثر بر انتقال ژن به گیاه ترشک مورد بررسی قرار گرفت. از اگرو باکتریوم، سویه LBA4404 حاوی پلاسمید pBI121، وغلظتهای مختلف کانامایسین و زمان‌های مختلف تلقیح با استفاده از ریز نمونه برگ برای ارزیابی انتقال ژن گزارشگر gus استفاده گردید. کشت قطعات برگ روی محیط کشت MS دارای 5/1 میلی‌گرم در لیترBAP و 75/0 میلی‌گرم در لیترIAA و غلظت‌های کانامایسین صفر، 10، 25، 50، 75 و 100 میلی گرم...
متن کاملRelationship between Respiration and Photosynthesis in Guard Cell and Mesophyll Cell Protoplasts of Commelina communis L.
A mass spectrometric method combining (16)O/(18)O and (12)C/(13)C isotopes was used to quantify the unidirectional fluxes of O(2) and CO(2) during a dark to light transition for guard cell protoplasts and mesophyll cell protoplasts of Commelina communis L. In darkness, O(2) uptake and CO(2) evolution were similar on a protein basis. Under light, guard cell protoplasts evolved O(2) (61 micromole...
متن کامل3-O-Galloylated Procyanidins from Rumex acetosa L. Inhibit the Attachment of Influenza A Virus
Infections by influenza A viruses (IAV) are a major health burden to mankind. The current antiviral arsenal against IAV is limited and novel drugs are urgently required. Medicinal plants are known as an abundant source for bioactive compounds, including antiviral agents. The aim of the present study was to characterize the anti-IAV potential of a proanthocyanidin-enriched extract derived from t...
