background: indirect genetic diagnosis using polymorphic dna markers can detect carriers of hemophilia a. this technique is preferable in developing countries because of its simplicity and cost effectiveness compared to direct mutation analysis. in the present study, we examined usefulness of intragenic marker bcl i restriction fragment length polymorphism (rflp) at intron 18, for carrier detec...

out of fifty-two iranian nonaflatoxigenic strains of aspergillus flavus, which were collected from various substrates (soil and kernel) and sources (peanut, corn and pistachio), fifteen representatives were selected according to their different geographical origins (six provinces: guilan and golestan, ardebil, fars, kerman and semnan) and vegetative compatibility groups (vcgs, ir1 to ir15) for ...

Molecular markers and mapping are used to analyze an organism’s genes. They allow the selection of target genetic areas based on marker genotype (and not trait phenotype), facilitate study variability diversity, create linkage maps, follow individuals or lines carrying certain may be select parental genotypes, remove drag in back-crossing, choose difficult-to-measure characteristics. Due a lack...

An early and fundamental step of the laminar organization of developing neocortex is controlled by the developmental programs that critically depend on the activities of reelin-positive cells in the marginal zone. However, the ontogeny of reelin-positive cells remained elusive. To gain insights into the spatial and temporal regulation of reelin-positive marginal zone cell development, we used a...

Prophet of POU1F1 (PROP1) plays direct or indirect important roles in the morphogenesis of pituitary gonadotropes as well as lactotropes, somatotropes and caudomedial thyrotropes. It also controls the expression of growth hormone, prolactin and thyrotropin subunits through regulatory PIT1 factor. These hormones have important influences on production traits in most animal species including the ...

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...
