Phosphorus (P), in the form of phosphate ion (Pi), is a vital element contributing in biomolecule structures, metabolic reactions, signaling pathways and energy transfer within the living cells. The objective of the present study was to assess the influence of fungal infection on Pi metabolism in compare to the effects of phosphate stress in Arabidopsis. Quantification of total P contents showe...

Most plant species are sensitive to high ammonium concentrations. In this experiment the sensitivity of lettuce and spinach to ammonium was investigated. In a factorial experiment with framework of a completely randomized design with two factors, nitrogen form (ammonium and nitrate) and plant species (lettuce and spinach), and three replications seeds were germinated in a mixture of perlite, sa...
determination of uranium in natural water and complex solutions using ion exchange chromatography: a combined procedure using ion exchange chromatography and uv-vis spectrophotometry techniques has been developed to measure uranum in natural water and complex solutions. after conditicing , one hundred milli liters of sample solutions have been passed through an ion exchange column,pachked with ...
In transgenic tobacco plants containing a pea ferredoxin transcribed region (Fed-1) driven by the cauliflower mosaic virus 35S promoter (P35S), light acts at a post-transcriptional level to control the abundance of Fed-1 mRNA in green leaves. To determine whether the light signal for this response involves photosynthesis, we treated transgenic seedlings with or without 3-(3,4-dichlorophenyl)-1,...
Rice stripe disease, caused by Rice stripe virus (RSV), is one of the most serious rice diseases in temperate and subtropical regions of the world. Since RSV is not transmissible mechanically, an insect transmission test was the original basis for identification of the viral population and cultivar resistance. A simple, rapid and reliable method is described by which virus-free small brown plan...
پس از بازنگری کلی بر تکنولوژی soi مدل و ترانزیستورهای soi و انواع روش های تبدیل سیگنال آنالوگ به دیجیتال مورد بررسی قرار می گیرد. در ادامه با طراحی زیرمدارهای مبدل a/d فلاش سه بینی اثر تکنولوژی soi بر این مدل بررسی می شود. مدل های soi بکاررفته از دانشگاه برکلی و پارامترهای آنها از دانشگاه فلوریدا تهیه شده و شبیه سازی مدارات بوسیله نرم افزار pspice5.0 و spice-opus انجام شده است. براساس شبیه سازی...
nowadays, the development of anti cancer drugs is an important subject in pharmacology. bisphosphonates (b.p) are a great choice for design and production of the types of drugs which not only could perform as anti cancer agents but also could inhibit the function of acetyl cholinesterase (ache). ache hydrolyzes the acetylcholine (which is a neurotransmitter in nervous system) using the oh in i...
Effects of nutrient solutions on quantitative and qualitative indices of tulip (Tulipa gesneriana cv. Apricot parrot) were studied in a completely randomized design with 5 nutrient solutions, 4 experimental units and 3 replications. Plants were fed with five nutrient solutions (S1, S2, S3, S4 and S5) having NH4+-N/total N ratios of 0, 0.038, 0.074, 0.11 and 0.14, respectively. All nutrient solu...
