Temperament is an important production trait in cattle and multiple strategies had been developed to generate molecular markers assist animal selection. As nonsynonymous single nucleotide polymorphisms are with the potential affect gene functions, they could be useful predict phenotypic effects. Genetic selection of less stress-responsive, temperamental animals desirable from economic welfare point view.

For most domestic animal species, including bovines, it is difficult to identify causative genetic variants involved in economically relevant traits. The candidate gene approach efficient because investigates genes that are expected be associated with the expression of a trait and defines whether variation present population phenotypic diversity. A potential limitation this identification candidates. This study used bioinformatics via search guided by functional interaction network.A network...

SNP located CACNG4, EXOC4, NRXN3, and SLC9A4 candidate genes were genotyped 250 animals with records exit velocity, pen score, score. Rs3423464051:G>A CACNG4 gene associated velocity An silico analysis five showed that alternative alleles CACNG4-rs3423464051, [...]

Fall armyworm, Spodoptera frugiperda (J.E. Smith), is an important pest that damages agriculture worldwide. Organophosphorus insecticides are used for its control; however, intensive and inadequate use of has selected resistance. The ace-1 gene confers cross resistance to organophosphorus carbamate in cholinergic synapses. SNPs associated with insecticide were searched using resequencing the populations S. from eight municipalities at Zacatecas, Mexico: Calera, Fresnillo, General R. Murguía,...

Cypermethrin (CYP) is an insecticide pyrethroid used in the agriculture for its broad-spectrum activity. However, recent studies have shown accumulation of CYP soil, and water a high toxicity against different species, including humans. On other hand, use bacteria bioremediation represents eco-friendly alternative removal xenobiotics. In this study, aim was to isolate identify from agricultural soils determine their ability tolerate biodegrade CYP. Additionally, some metabolites...
