The research is aimed at studying economically valuable traits and genetic control of resistance to leaf-stem diseases, photoperiodic reaction short stemming soft spring wheat variety Semenovna, created by scientists the Omsk Agrarian Scientific Center (Russia) North Kazakhstan Agricultural Experimental Station (Kazakhstan). Using methods state testing, molecular genetics in vitro methods, morp...

The avianuncoupling protein (avUCP) is a member of the mitochondrial transporter superfamily that uncouples proton entry in the mitochondrial matrix from ATP synthesis. The polymerase chain reaction restriction fragment length polymorphism (PCR-RFLP) method was used to estimate the allele and genotype frequencies of the UCP/HhaI polymorphisms and to determine associations between these polymorp...

the use of proteins and peptides as human therapeutics has been increased in recent years. lipase is a relatively homogeneous proteinaceous enzyme indicated in maldigestion. the purpose of the present study was to evaluate the effect of humidity along with compactional pressure on the enzymatic activity of wheat germ lipase. samples of lipase powder were kept at different relative humidity (rh)...

to study the effects of different amounts of sulphur and boron fertilizers on grain yield and grain quality of bread wheat cultivar pishtaz, an experiment was conduncted in karaj during two cropping seasons 2001-2003. three levels of sulphur (s0= 0, s1=250 and s2= 500 kgha-1) and three levels of boron (b0= 0, b1= 20 and b2= 40 kgha-1) were different treatments of the experiment arranged in rcbd...

the genome of iranian wheat stripe virus (iwsv), a tentative member of the genus tenuivirus, is comprised of three ambisense and one negative sense rna segments. the coat and non-structural proteins encoded by the vcrna3 and vrna4 genes, respectively, were efficiently translated in vitro. translated proteins of vcrna3 and vrna4 transcripts were approximately 35000 and 22000 in mr, respectively,...

Bread wheat landraces are considered among important gene sources for quality breeding programs. This study aims to compare thousand kernel weight crude protein ratio, dry gluten grain hardness and zeleny sedimentation results of 20 bread lines selected from 5 registered cultivars in order determine future candidates Field experiments were conducted the consequent 2012-2013 2013-2014 growing se...

We have isolated, sequenced, and expressed a cold-specific cDNA clone, Wcs120, that specifically hybridizes to a major mRNA species of approximately 1650 nucleotides from cold-acclimated wheat (Triticum aestivum L.). The accumulation of this mRNA was induced in less than 24 hours of cold treatment, and remained at a high steady-state level during the entire period of cold acclimation in the two...

Freezing tolerance in plants is a complex trait that occurs in many plant species during growth at low, nonfreezing temperatures, a process known as cold acclimation. This process is regulated by a multigenic system expressing broad variation in the degree of freezing tolerance among wheat cultivars. Microarray analysis is a powerful and rapid approach to gene discovery. In species such as whea...

ABSTRACT The effect of plant density on disease is not well understood in populations of a single host plant genotype and has been studied even less in mixtures of host genotypes. We performed an experiment to evaluate the effect of wheat planting density on infection by Puccinia striiformis in experimental plots with a single wheat genotype and in plots with two genotypes making up a range of ...
