quantitative traits locus for milk production traits has been described on centromeric end of bovine chromosome 14. reports name the acyl coa: diacylglycerol acyltransferase (dgat1) gene as a potential candidate gene with dinucleotide substitution (aa to gc) in exon viii which causes the change of lysine to alanine in amino acid (k232a).the aim of the present study was to estimate the frequency...

Mastitis is one of the most serious and costly diseases affecting dairy cattle production. In the present study, effects of a lactoferrin gene polymorphism (intron 6) on milk somatic cell count (SCC) and subclinical mastitis was investigated in 121 Holstein dairy cattle. Two alleles of A and B and two genotypes of AA and AB were found in an EcoRI recognized single nucleotide polymorphism in int...

quantitative trait loci (qtl) affecting milk production traits on bovine chromosome 6 close to the opn gene location have been identified through several whole genome scans. opn is a phosphoprotein, synthesized in a variety of tissues and cells and secreted into body fluids. in this study, dna was isolated from blood samples collected from 398 holstein cows in tehran and esfahan provinces. dna ...

C1-gas conversion for sustainable synthesis of fatty acids and ethanol: dynamics CODH/AdhE1 gene expression with biocatalyst selection.

ABSTRACT- In order to produce transgenic rice lines lacking selectable marker gene, biolistic co-transformation technique using gold nanoparticles was adopted. In the first step, the efficiency of different sizes of gold particles was evaluated. The results showed that the efficiency of the nanoparticles in the transformation was comparable to that of the micro particles. Subsequently, two sepa...
