Genetic modification of plants by the insertion of transgenes can be a powerful experimental approach to answer basic questions about gene product function. This technology can also be used to make improved crop varieties for use in the field. To apply this powerful tool to red clover, an important forage legume, a population of red clover with a high potential for regeneration in tissue cultur...
The community's obstacle in fulfilling basic commodities is price fluctuations. Price fluctuations are influenced by supply and demand. fluctuation frequently related to food needs of agricultural products since it sensitive climate change. Staple which often experiences red chili, shallot chicken egg. pandemic period impacted obstructed the community activities, including trading especially ma...
Introduction The red:far-red ratio (R:FR) is a key variable in many biological processes from basic ones such as the response of phytochrome to more integrated ones, such as tillering or weed competition. Accurate estimation of the red:far-red ratio of plant organs in field condition is an important issue to be able to integrate the increasing knowledge on phytochrome-driven processes from cell...
در این مطالعه پس از تعیین غلظت مناسب ال- کارنیتین بر رشد و تکثیر سلول ها با استفاده از آزمون mtt (متیل تیازول تترازولیوم)، اثر ماده ال-کارنیتین به عنوان یک آنتی اکسیدان در غلظت های به دست آمده بر پیری mscs مشتق از بافت چربی رت به روش رنگ آمیزی بتاگالاکتوزیداز مورد بررسی قرارگرفته و سپس پتانسیل تمایزی این نوع سلول ها به بافت استخوان و چربی با استفاده از روش rt-pcr و همچنین رنگ آمیزی های oil red ...
امروزه گسترش شهرها باعث تغییر قابل توجهای در استفاده از زمین و عوامل محیطی، به ویژه در بیشتر شهرهای بزرگ شده است . با توجه به رشد جمعیت و تغییراتی که هر روزه در شهرها در حال وقوع هستند، بایستی در برنامهریزی های اجتماعی، اقتصادی و محیطی شهرها، رشد کیفیت زندگی و حفظ محیط شهری مد نظر قرار گیرد.بسیاری از شهرها در حال حاضر مصرف کننده سوخت فسیلی ، استفاده کننده از زمین و تولیدکننده مواد زائد هستند....
This paper aims to evaluate the simultaneous adsorption of basic red 2 (BR2) and violet 3 (BV3) in a binary system batch mode using date stones as low cost adsorbents. For both dyes, experimental kinetic data were well fitted by Brouers–Sotolongo model (R =0.99) intraparticle diffusion was controlling step mass transfer mechanisms. The extent found be lower for BR2 (1.13×10 -11 cm /s) than BV3 ...
To obtain basic information on the detection of cellulolytic activity in Auricularia auricula-judae, the influences of dye reagent, pH, and temperature were assessed. Chromogenic dye (congo red, phenol red, remazol brilliant blue, and trypan blue) was individually incorporated into a medium containing either carboxymethyl-cellulose, Avicel, or D-cellobiose as a polysaccharide carbon substrate. ...
At the core of the circadian network in Arabidopsis (Arabidopsis thaliana), clock genes/proteins form multiple transcriptional/translational negative feedback loops and generate a basic approximately 24-h oscillation, which provides daily regulation for a wide range of processes. This temporal organization enhances the fitness of plants only if it corresponds to the natural day/night cycles. Li...
In their recent studies (20) on the water and electrolyte distribution between cells and serum, Van Slyk‘e, Wu, and McLean assumed for their theoretical considerations that the red hlood cells were impermeable to the cations sodium and potassium. They showed that when the serum anion concentration was changed in .whole blood COz saturation experiments, the reestablishment of electrolyte equilib...
