this research was conducted in two protect and destroy region in the middle zagros, in illam province. in order to identification of ecological species group and evaluate density of regeneration, effect of many factors such as protection, vegetation, physiographic factors, physical and chemical properties of soil in study locations were studied. to achieve these purpose number of 54 plots using...
Temperament is fundamental to animal production due to its direct influence on the animal-herdsman relationship. When compared to calm animals, the aggressive, anxious or fearful ones exhibit less weight gain, lower reproductive efficiency, decreased milk production and higher herd maintenance costs, all of which contribute to reduced profits. However, temperament is a trait that is complex and...
High-density SNP arrays for genome-wide assessment of allelic variation have made high resolution genetic characterization of crop germplasm feasible. A medium density array for apple, the IRSC 8K SNP array, has been successfully developed and used for screens of bi-parental populations. However, the number of robust and well-distributed markers contained on this array was not sufficient to per...
OBJECTIVES The thickness of the brain's cortical gray matter (GM) and the fractional anisotropy (FA) of the cerebral white matter (WM) each follow an inverted U-shape trajectory with age. The two measures are positively correlated and may be modulated by common biological mechanisms. We employed four types of genetic analyses to localize individual genes acting pleiotropically upon these phenot...
abstract this study examines the effect of teaching lexical inferencing strategies on developing reading comprehension skill of iranian advanced efl learners. participants were female students of meraj and shokouh institudes of garmsar a quasi-experimental design using two intact advanced classes of efl students at meraj and shokouh institutes. as the first step, a general toefl proficiency te...
Body weight is one of the most important economically useful traits, which characterized by complex inheritance. Therefore, a search for genetic mechanisms affecting its formation increased scientific interest. This work presents first time results genome-wide association studies in resource population sheep (Ovis aries) from backcross (Romanov à Katah-din) Romanov family, whose body was recor...
Dry direct-seeding of rice is rapidly increasing in China, but variable planting depth associated with machine sowing can lead to low seedling emergence rates. Phenotype analysis of 621 rice accessions showed that mesocotyl length (ML) was induced by deep soil covering and was important in deep-sowing tolerance in the field. Here, we performed and compared GWAS using three types of SNPs (non-sy...
Relative proportions of peripheral blood (PB) B lymphocytes (B220%) as well as CD4 (CD4%) and CD8 (CD8%) T lymphocytes differ significantly among inbred mouse strains: B220% is high in C57BL/6J (B6) and C57BR/cdJ, intermediate in BALB/cByJ (BALB) and DBA/2J (D2), and low in NOD/LtJ (NOD) and SJL/J (SJL) mice, whereas CD4% and CD8% are high in NOD and SJL mice and low in the other 4 strains. By ...
Central corneal thickness (CCT) is one of the most heritable ocular traits and it is also a phenotypic risk factor for primary open angle glaucoma (POAG). The present study uses the BXD Recombinant Inbred (RI) strains to identify novel quantitative trait loci (QTLs) modulating CCT in the mouse with the potential of identifying a molecular link between CCT and risk of developing POAG. The BXD RI...
The mechanisms underlying host resistance to Mycobacterium avium subsp. paratuberculosis (MAP) infection are largely unknown. In the current study, we hypothesize that cows with an ability produce higher levels of interferon-gamma (IFNɣ) might control MAP more successfully. To test this hypothesis, IFNɣ production was measured using a specific ELISA kit in avian purified protein derivative (aPP...
