in order to study the role of photosynthetic tissues on grain filling and remobilization of stem reserves under terminal drought, a pot experiment as semi-field was conducted as two-factor factorial in complete randomized design with three replicates at research farm of agriculture college of vali – e – asr university of rafsanjan during january to june 2012 . first factor was source strength r...

cold stress is one of the limiting factors in production of greenhouse vegetables. chemicals offer useful approach to reduce low temperature-induced damages. this study was conducted to evaluate the effect of foliar application of methyl jasmonate (meja) at concentrations of 0 (control), 50, 100, 200 µm) on electrolyte leakage (el), relative water content (rwc), soluble carbohydrates, proline, ...

The disc gel electrophoretic patterns obtained with skin test-active (mycelial and yeast) antigens of Blastomyces dermatitidis were compared. As would be expected, the blastomycins (mycelial-phase) and the cytoplasmic ultrafiltrates (yeast-phase) were heterogeneous mixtures containing proteins, glycoproteins, lipoproteins, and carbohydrates. The skin test-active cytoplasmic ultrafiltrates and t...

Carbohydrates and derivatives (such as glycolipids, glycoproteins) are of critical importance for cell structure, metabolism and functions. The effects of carbohydrate and lipid metabolic imbalances most often cause health disorders and diseases. In this study, new carbohydrate-based nanobioconjugates were designed and synthesized at room temperature using a single-step aqueous route combining ...

I. The role of carboxyl groups in the binding of specific carbohydrates to concanavalin A, the phytohemagglutinin of the jack bean, has been studied using two techniques: (I) H + titration in the presence and absence of methyl a-D-mannopyranoside, a specifically bound carbohydrate ligand and (2) chemical modification of the protein carboxyl groups employing glycine methyl ester and a water-solu...

in order to investigate the role of bacillus cogulans on yield of two forage corn cultivars, an experiment carried out at agricultural research center of tehran province during 2009-2010. the experiment design consisted of three randomized complete blocks in a factorial arrangement. investigated treatments consisted of the kind of phosphorus and cultivar. the phosphorus factor included of the a...

Symbiotic association of legumes with rhizobia frequently results in higher photosynthesis and soluble carbohydrates in comparison with nitrate-fed plants, which might improve its potential for biomass conversion into bioethanol. A greenhouse experiment was conducted to examine the effects of nitrogen source and water availability on stem characteristics and on relationships between carbohydrat...

Cynara cardunculus var. scolymus L. is a herbaceous perennial plant that could be drought tolerant once established after the first year. To evaluate the effects of water stress on growth parametersand forage quality of this plant, a field experiment was conducted using a randomized complete block design with three replications in Isfahan, Iran during 2013-2015. Treatments wer...

BACKGROUND At initial steps of rehydration from cryptobiosis of anhydrobiotic organisms or at rehydration of dry tissues the liquid 1H NMR signal increased anomaly. The surplus in liquid signal may appear if some solid constituents dissolved, or if they were decomposed by enzymatic action. METHODS Hydration kinetics, sorption isotherm, 1H NMR spectra and high power relaxometry were applied to...
