DNA sequence polymorphism and codon usage bias were investigated in a set of 41 nuclear loci in the Pacific oyster Crassostrea gigas. Our results revealed a very high level of DNA polymorphism in oysters, in the order of magnitude of the highest levels reported in animals to date. A total of 290 single nucleotide polymorphisms (SNPs) were detected, 76 of which being localised in exons and 214 in non-coding regions. Average density of SNPs was estimated to be one SNP every 60 bp in coding regions and one every 40 bp in non-coding regions. Non-synonymous substitutions contributed substantially to the polymorphism observed in coding regions. The non-synonymous to silent diversity ratio was 0.16 on average, which is fairly higher to the ratio reported in other... |

Tibetan (TB) and Bama (BM) miniature pigs are two popular pig breeds that are used as experimental animals in China due to their small body size. Here, we analyzed single-nucleotide polymorphisms (SNPs) in gene fragments that are closely related to growth traits [growth hormone (GH), growth hormone receptor (GHR), and insulin-like growth factor (IGF)-1)] in these pig breeds and a large white (LW) control pig breed. On the basis of the analysis of 100 BMs, 108 TBs, and 50 LWs, the polymorphic distribution levels of GH, GHR, and IGF-1 were significantly different among these three pig breeds. According to correlation analyses between SNPs and five growth traits - body weight (BW), body length (BL), withers height (WH), chest circumference (CC), and abdomen... |

ABSTRACT In this study, POU1F1 gene polymorphism was detected in five sheep populations (large-tailed Han, small-tailed Han, Yuxi fat-tailed, Lanzhou large-tailed, and Mongolian sheep), using DNA pooling and sequencing, to provide theoretical basis for the breeding of excellent sheep varieties. Three single-nucleotide polymorphism (SNP) loci of POU1F1 gene were detected in five sheep populations, namely C355T (C/T), C71G (C/G), and C330G (C/G). C and T frequencies of C355T were 0.67/0.33, 0.81/0.19, 0.67/0.33, 1.00/0.00, and 0.93/0.07, respectively, in large-tailed Han, small-tailed Han, Yuxi fat-tailed, Mongolian, and Lanzhou large-tailed sheep. C of C355T locus was the dominant allele in five sheep populations. C and G allele frequencies of C330G locus... |

A raça Canchim tem possui pouca gordura de cobertura o que limita o valor da carcaça produzida. O cromossomo 4 já foi associado com deposição de gordura em bovinos. O gene IGFBP3 foi relacionado ao metabolismo de gorduras e encontra-se no cromomosso 4. Este trabalho objetivou identificar polimorfismos no gene IGFBP3, investigar associação desses SNPs com espessura de gordura, área de olho de lombo e peso aos 18 meses de bovinos da raça Canchim. Um total de 647 animais, compreendendo machos e fêmeas, nascidos de 2003 a 2006, criados em regime de pastagem em oito fazendas localizadas nos estados de SP e GO, foi avaliado para espessura de gordura subcutânea, área de olho de lombo e peso aos 18 meses de idade. Para a identificação dos SNPS foram calculados os... |

ABSTRACT: The main application of genomic selection (GS) is the early identification of genetically superior animals for traits difficult-to-measure or lately evaluated, such as meat pH (measured after slaughter). Because the number of markers in GS is generally larger than the number of genotyped animals and these markers are highly correlated owing to linkage disequilibrium, statistical methods based on dimensionality reduction have been proposed. Among them, the partial least squares (PLS) technique stands out, because of its simplicity and high predictive accuracy. However, choosing the optimal number of components remains a relevant issue for PLS applications. Thus, we applied PLS (and principal component and traditional multiple regression)... |

ABSTRACT Myostatin (MSTN) is a negative regulator of skeletal muscle growth. In order to investigate whether there is a correlation between MSTN polymorphisms and chicken production performance, in this study, single nucleotide polymorphisms (SNPs) in MSTN gene were examined across 180 Daheng broilers by direct sequencing of PCR product, and the correlations between the genotype and body weight at the age of 1-10 weeks and carcass traits at the age of 73 day were analyzed. Five SNPs (rs313622770, rs313744840, rs316247861, rs314431084, rs317126751) of MSTN gene were identified across Daheng broiler samples, and four haplotypes were reconstructed based on the five SNPs. Results of association analysis showed that four (rs313622770, rs313744840, rs316247861... |

Selective breeding strategies require pedigree information over generations, but many species produced in aquaculture are too small to be physically tagged at early stages. Consequently, maintaining a sufficient number of separate families is often needed but costly and logistically difficult. Alternatively, parentage assignment can be obtained using DNA markers. We developed a panel of single nucleotide polymorphism (SNP) markers for the European abalone Haliotis tuberculata using an existing transcriptomic resource. An initial set of 2,176,887 SNPs was filtered to select 500 for high throughput genotyping. Of these, 298 SNPs were amplified in at least 90% of our H. tuberculata samples, consisting of a mixed family cohort (945 offspring) generated by... |

A pungência em frutos de pimenta do gênero Capsicum, devido à presença de capsaicinóides, é uma das características mais atrativas e muito valorizadas pela culinária mundial. Neste trabalho, objetivou-se validar e avaliar a eficiência de predição dos marcadores moleculares pun1¹, pun1³ e o SNP identificado pelo método tetra-primer ARMS-PCR para a determinação de pungência em acessos de Capsicum spp. Trinta e seis acessos do Banco de Germoplasma da Universidade Federal de São Carlos foram avaliados através de análises sensoriais (em frutos maduros) e moleculares para pungência (na fase de plântula através da extração do DNA em folhas). Os marcadores SNP ARMS-PCR, pun1¹ e pun1³ foram usados na avaliação molecular. Os resultados mostram a eficiência desses... |
