Authors: H.O. Santos, E.V.R. Von Pinho, I.V. Von Pinho, S.M.F. Dutra,T. Andrade and R.M. Guimar�£es
Phytohormones have different characteristics and functions, and they may be subject to changes in their gene expression and synthesis during seed development. In this study, we evaluated the physiological qualities of habanero peppers (Capsicum chinense Jacquin) during seed development and the expression of genes involved in germination. Seeds were obtain.. Read More»

Effect of a high-concentrate diet on milk components and mammary health in Holstein dairy cows
Authors: Z.L. Xie, J. Zhang, D.M. Zhang, J.F. Li, Y.H. Lin
The poor egg-laying rate of geese hinders the development of the goose industry; therefore, the reproductive performance of geese is an important area of investigation. To evaluate the relationship between photoperiod, reproductive hormones, and reproductive activity during the egg-laying cycle in geese under natural condition.. Read More»

Effect of high-concentrate diet on amino acid transporter expression and milk quality in Holstein dairy cows
Authors: Z.L. Xie, P.S. Ye, Y.S. Zhang and X.Z. Shen
In order to evaluate the effect of high-concentrate diet supplementation on milk protein content, six Holstein dairy cows were assigned into high-concentrate diet (HC) or low-concentrate diet (LC) groups (N = 3/group) for 50 days. With regard to milk protein, HC feeding significantly reduced the percentage of milk protein (P < 0.01), and milk protein y.. Read More»

Investigation of TG gene variants and their effects on growth, carcass composition, and meat quality traits in Chinese steers
Authors: Investigation of TG gene variants and their effects on growth, carcass composition, and meat quality traits in Chinese steers
Thyroid hormones play an important role in regulating metabolism and can affect metabolism-related traits such as fat deposition. The thyroglobulin (TG) gene produces the precursor of thyroid hormones and has been proposed as a candidate gene for a quantitative trait locus with an effect on fat deposition. In this study, we identified 4 novel single nucle.. Read More»

Association of CAPN1 316, CAPN1 4751 and TG5 markers with bovine meat quality traits in Mexico
Authors: C.A. Bonilla, M.S. Rubio, A.M. Sifuentes, G.M. Parra-Bracamonte, V.W. Arellano, M.R.D. M�©ndez, J.M. Berruecos and R. Ortiz
We examined allele and genotype frequencies for the molecular markers CAPN1 316, CAPN1 4751 and TG5, and determined whether they are associated with beef quality traits in Mexican cattle. One hundred and twenty-four longissimus dorsi muscle samples were collected from cattle from north, central and southern Mexico. CAPN1 316 a.. Read More»

Association of SNPs on CAPN1 and CAST genes with tenderness in Nellore cattle
Authors: L.F.B. Pinto, J.B.S. Ferraz, F.V. Meirelles, J.P. Eler, F.M. Rezende, M.E. Carvalho, H.B. Almeida and R.C.G. Silva
We examined whether single-nucleotide polymorphisms (SNPs) in the calpain (CAPN) and calpastatin (CAST) genes, described from Bos primigenius taurus, are polymorphic in Nellore cattle. We also looked for a possible association of linkage disequilibrium of this polymorphism with tenderness of the longissimus dorsi muscle after .. Read More»

Back fat thickness and meat tenderness are associated with a 526 T�A mutation in the exon 1 promoter region of the MyF-5 gene in Chinese Bos taurus
Authors: J.A. Ujan, L.S. Zan, S.A. Ujan, C. Adoligbe and H.B. Wang
Qualitative trait loci (QTL) for growth and meat quality traits in cattle (Bos taurus) have been previously mapped to three chromosome regions, 0 to 30, 55 to 70, and 70 to 80 cM on chromosome 5. We evaluated the allele frequencies and gene-specific single nucleotide polymorphisms (SNPs) of bovine myogenic factor 5 (MyF-5) in .. Read More»

The somatotropic axis is a major regulatory pathway of energy metabolism during postnatal growth in mammals. Genes involved in this pathway influence many economically important traits. The association of selected SNPs in these genes with carcass traits was examined in grazing Brangus steers. These traits included final live w.. Read More»

A novel polymorphism of the MYPN gene and its association with meat quality traits in Bos taurus
Authors: Y. Jiao, L.S. Zan, Y.F. Liu, H.B. Wang and B.L. Guo
Myopalladin (MYPN) is a multifunctional protein that maintains sarcomeric integrity and regulates Z-line structure. It is an important candidate gene for meat quality selection through marker-assisted selection. Using PCR-RFLP technology, we discovered a single-nucleotide polymorphism (SNP) (A1795G in exon 9) of the MYPN gene... Read More»
