| Association analysis was applied to a panel of accessions of Embrapa Rice Core Collection (ERiCC) with 86 SSR and field data from two experiments. A clear subdivision between lowland and upland accessions was apparent, thereby indicating the presence of population structure. Thirty-two accessions with admixed ancestry were identified through structure analysis, these being discarded from association analysis, thus leaving 210 accessions subdivided into two panels. The association of yield and grain-quality traits with SSR was undertaken with a mixed linear model, with markers and subpopulation as fixed factors, and kinship matrix as a random factor. Eight markers from the two appraised panels showed significant association with four different traits,... |

| Abstract Based on RNA-seq analysis, we recently found that the bovine NCAPG (non-SMC condensin I complex, subunit G) gene is differentially expressed during development of the longissimus muscle. In the present study, we validated this result and, using quantitative real-time PCR analysis, identified two adjacent genes, LCORL and DCAF16, that are more abundant in fetal muscle tissue; further analysis of tissue-specific expression patterns indicated high abundance of NCAPG in muscle. Since no polymorphisms were detected in a previous study of Qinchuan cattle, we extended our investigation to examine the occurrence of single-nucleotide polymorphisms (SNPs) in the NCAPG gene. Three SNPs, i.e., one located in the intron region (g47747: T > G), a synonymous... |

| 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... |
