[ 1 ] - افزایش بیان ژن آنزیم p-کومارات 3-هیدروکسیلاز و ترکیبات فنیل پروپانوئیدی تحت تاثیر کیتوزان در کشت سلولی گل میمونی سازویی (Scrophularia striata)
Chitosan is the main compounds of fungal species cell walls and as biotic elicitors could be used to improve secondary metabolites. In this study, we have verified the time-course of cell growth, phenylpropanoid compounds ( total phenol, flavonols, flavonoids and echinacoside) production in cells treated with chitosan. To study mechanism of chitosan action, expression of p-coumarate 3-hydroxyla...
[ 2 ] - A Conceptual Analysis of Retrogression of Uromie Lake and Progression of Plant Species
The importance of Uromie Lake National park and Biosphere Reserve associated with is known worldwide and thus, maintaining its optimized well-being and values are on the priority list of preserving, rehabilitation and ecologic management programs. Plants, as primary producers of the greater Uromie Lake ecosystem, despite their greater diversity have covered much lesser areas primarily becaus...
[ 3 ] - Polycyclic Aromatic Hydrocarbons (PAHs) in Plants of Shadegan Wetland: Halocnemum strobilaceum and Suaeda maritima
Plants are known to bioaccumulate many contaminants. Petroleum-derived compounds, such as saturated hydrocarbons and PAHs are widespread persistent environmental contaminants. Deposition of soot and precipitation of black rain have occurred in the Shadegan Wetland. In this study, PAHs in plant parts of two prominent species of halophytes, Halocnemum strobilaceum and Suaeda maritima were determi...
[ 4 ] - معرفی برخی میکوریزای گونه های گیاهی در جنگل خیرودکنار
همزیستی میکوریزا در جذب عناصر مورد نیاز گیاه و تامین آب آن پراهمیت است و در کشاورزی، جنگلکاری و مرتعداری کاربرد فراوان دارد. به همین دلیل، این تحقیق برای بررسی اثر ارتفاع و نیز عوامل محیطی همچون دما، میزان بارندگی، شوری، نوع بافت خاک و ترکیب عنصری خاک بر نوع و پراکنش میکوریزا در جنگل تحقیقاتی خیرودکنار انجام شد. نمونهبرداری از 8 ایستگاه از ساحل دریا تا ارتفاع 504 متری و از محل سایهانداز درختان ...
[ 5 ] - Differential responses of two Iranian rice cultivars to arsenite toxicity
Arsenic (As) is a toxic metalloid which is usually found in rice fields as a contamination and has negative effects on the plant growth and reduces the crop yield. Similar to heavy metals, the deleterious effects of As may be due to, at least in part, the amount of absorbed As and disturbance of the plant water status. I...
