| A raça Morada Nova foi formada na região Nordeste do Brasil, a partir de cruzamentos de ovelhas de origem portuguesacom ovinos deslanados africanos, introduzidos no período colonial. Devido à sua excelente adaptabilidade e boa eficência alimentar nas condições áridas do Nordeste brasileiro, essa raça é considerada de grande importância econômica. Com o objetivo de conhecer a variabilidade genética da raça Morada Nova bem como verificar possível diferenciação genética entre suas subpopulações, genotiparam-se 50 indivíduos, oriundos de Pernambuco ? MN1 (n=20) e de São Paulo - MN2 (n=30), utilizando-se 30 microssatélites. |

| MicroRNAs (miRNAs, miRs) encompass a class of small non-coding RNAs that often negatively regulate gene expression. miRNAs play an essential role in skeletal muscle, determining the proper development and maintenance of this tissue. In comparison to other organs and tissues, the full set of muscle miRNAs and its expression patterns are still poorly understood. In this report, a chicken skeletal muscle miRNA library was constructed, and the expression of selected miRNAs was further characterized during muscle development in chicken lines with distinct muscling phenotypes. Clone library sequence analysis revealed 40 small RNAs with similarities to previously described chicken miRNAs, seven miRNAs that were never identified before in chicken, and some... |

| Genetic selection for production traits has resulted in a rapid improvement in animal performance and development. Previous studies have mapped quantitative trait loci for body weight at 35 and 41 days, and drum and thigh yield, onto chicken chromosome 4. We investigated this region for single nucleotide polymorphisms and their associations with important economic traits. Three positional candidate genes were studied: KLF3 (Krüeppel-like factor 3), SLIT2 (Slit homolog 2), and PPARGC1A (peroxisome proliferator-activated receptor gamma, coactivator 1 alpha). Fragment sequencing of these genes was conducted in 11 F1 animals, and one polymorphism in each gene was selected and genotyped in an F2 population (N = 276) and a paternal broiler line TT (N = 840).... |
