Stability and Synthesis of Phospholipids during Desiccation and Rehydration of a Desiccation-Tolerant and a Desiccation-Intolerant Moss.
The fatty acid composition of the phospholipids from the desiccation-tolerant moss Tortula ruralis (Hedw.) Gaertn, Meyer and Scherb and the desiccation-intolerant moss Cratoneuron filicinum has been determined. No changes in composition occur in either moss as a consequence of rapid drying, but, after slow drying, there is a decline in some unsaturated fatty acids. Upon rehydration of T. rurali...
متن کاملMembrane Organization of the Desiccation-Tolerant Moss Tortula ruralis in Dehydrated States.
Membrane organization of the desiccation tolerant moss Tortula ruralis was studied in several intensely dehydrated states (75% relative humidity [RH], 90% RH, plasmolysis in molar salt, freezing to -20 degrees C) by (31)P nuclear magnetic resonance and ultrastructural analyses. Both methods revealed that even at 75% RH (-400 bars), the moss cellular membranes retained extended phospholipid bila...
متن کاملPolyribosomes Conserved during Desiccation of the Moss Tortula ruralis Are Active.
During desiccation of the moss Tortula ruralis (Hedw.) (Gaertn, Meyer and Scherb) polyribosomes are conserved. On rehydration, protein synthesis is rapidly resumed. In the presence of protein synthesis initiation inhibitors ribosome run-off from the conserved polyribosomes takes place, confirming that these retain their activity as intact structures during desiccation.
متن کاملProtein dynamics in thylakoids of the desiccation-tolerant plant Boea hygroscopica during dehydration and rehydration.
Plants of Boea hygroscopica F. Muell were dehydrated to 9% relative water content (RWC) by withholding water for 26 d, and afterward the plants were rehydrated. Leaves were taken from control plants after 7, 12, and 26 d from the beginning of dehydration, and after 6 and 48 h from rehydration. The RWC decreased by 80% during dehydration, but the leaves regained RWC with rehydration. Dehydrated ...
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...
