for study the effect of arbuscularmycorrhiza fungi a factorial experiment in a randomized complete block design with four replications was carried out in the summer of 1389 at the agricultural research station in city of zahak. the experiment included two factors; the first factor was inoculated glomus mossea mycorrhiza and no-inoculated one. the second factor was in four varieties of corn: s.c...

the present experiment was conducted to determine nutritional values of wild pistachio trees (p. khinjuk) leaves it's use it in the diet of sheep. initially chemical composition of p. khinjuk leaf was determined. the diets containing 0, 5, 10, 15, 20, 25 and 30% of p. khinjuk leaf were prepared and used for sheep to determine the best replacement level of it with corn silage. fermentation ...

PII protein in bacteria is a sensor for 2-oxoglutarate and a transmitter for glutamine signaling. We identified an OsGlnB gene that encoded a bacterial PII-like protein in rice. Yeast two-hybrid analysis showed that an OsGlnB gene product interacted with N-acetylglutamate kinase 1 (OsNAGK1) and PII-like protein (OsGlnB) itself in rice. In cyanobacteria, NAGK is a key enzyme in arginine biosynth...

Cassava (Manihot esculenta Crantz) is the third-largest carbohydrate food source in tropical region after rice and corn. Its flesh used to produce foods, while other parts of plant are not fully exploited. This research aimed evaluatetheproximate composition cassava (Rayong 90 variety). Six different namely leaf, petiole, young stem, tuber, cortex periderm white variety plants were dried powder...

drought is one of the most important factors limiting crop yields around the world. drought stress in plants, the change (increase or decrease) in the production of plant proteins. this research was carried out using bread wheat genotypes. for evaluation of leaf protein pattern in wheat, 10 genotypes were assayed with 3 replications under irrigated (non-stress) and rain-fed (stress) conditions....

To gain insight into the processes controlling leaf development, we characterized an Arabidopsis mutant, varicose (vcs), with leaf and shoot apical meristem defects. The vcs phenotype is temperature dependent; low temperature growth largely suppressed defects, whereas high growth temperatures resulted in severe leaf and meristem defects. VCS encodes a putative WD-domain containing protein, sugg...

the experiment was aimed at investigating the effects of defoliation (i. e. amanipulation of source size) at different times and with different intensities on yield, grain protein content and remobilization of dry matter from shoot to grain under various levels of soil moisture and nitrogen in winter wheat. two separate field experiments were conducted simultaneously under water stress vs irrig...

in order to evaluate of morphological, physiological and biochemical traits, related to drought tolerance, an experiment was carried out in field condition. in this study two commercial cultivars (mcc361, mcc358), three kabuli and three deci type of tolerant genotypes (mcc392, mcc537, mcc696, mcc873, mcc870, mcc10,) and three kabuli and three deci type of susceptible genotypes (mcc759, mcc588, ...

Leaf protein can be obtained cost-efficiently by alkaline extraction, but overuse of chemicals and low quality of (denatured) protein limits its application. The research objective was to investigate how alkali aids protein extraction of green tea leaf residue, and use these results for further improvements in alkaline protein biorefinery. Protein extraction yield was studied for correlation to...

Reversible protein phosphorylation mediated by protein kinases and phosphatases plays an important role in the regulation of leaf senescence. We previously reported that the leucine-rich repeat receptor-like kinase SENESCENCE-ASSOCIATED RECEPTOR-LIKE KINASE (AtSARK) positively regulates leaf senescence in Arabidopsis (Arabidopsis thaliana). Here, we report the involvement of a protein serine/th...
