background: with the increasing concern for health and nutrition, dietary fat has attracted considerable attention. the composition of fatty acids in the diet is important because they are associated with major diseases including cancers, diabetes, and cardiovascular disease. the fatty acid synthase (fasn) and stearoyl-coa desaturase (delta-9-desaturase) (scd) genes affect fatty acid compositio...

The identification of the efficiency of some mtDNA genes of Mus musculus species complex (house mouse) for biosystematics research was studied in this approach. Recent studies have made use of different mitochondrial genes including NADH dehydrogenase genes, cytochrome b gene, cytochrome oxidase genes, D-loop region and whole mtDNA genome to study the house mouse species. Usage of each of these...

pertussis is still endemic and the recently resurgence of the disease caused by bordetella pertussis has been shown in many countries. the polymorphism of the virulence genes of b. pertussis and lack of any information about the allelic variation between the iranian isolates promotes us to analysis of the genes encoded virulence factors including ptxs1, prn, fim3 and cya to understand the diffe...

septoria tritici blotch (stb), caused by the ascomycete fungus mycosphaerella graminicola (asexual stage: septoria tritici), is one of the most important foliar diseases of wheat. in this research, quantitative expression analysis of five candidate genes for the induction of resistance to stb (pr-1, bsi, msr, per, and ppi) was conducted in the wheat cultivars ‘seri 82’ (susceptible) and ‘fronta...

background: all aerobically growing organisms suffer from exposure to oxidative stress, caused by partially reduced forms of molecular oxygen, known as reactive oxygen species (ros). these are highly reactive and capable of damaging cellular constituents such as dna, lipids and proteins. consequently, cells from many different organisms have evolved mechanisms to protect their components agains...

Codon bias refers to the differences in the frequency of occurrence of synonymous codons in coding DNA. Pattern of codon and optimum codon utilization is significantly different between the lives. This difference is due to the long term function of natural selection and evolution process. Genetics drift, mutation and regulation of gene expression are the main reasons for codon bias. In this stu...
