Phenotypic characteristics for discrimination between advanced genotypes of Brachiaria ruziziensis
Authors: B.A. Rezende, C.B. Ribeiro, D.H.L. Teixeira, F.M.A. Gon?§alves and F. Souza Sobrinho
The aim of this study was to use multivariate methods and Pearson and partial correlations to disregard phenotypic characteristics that contribute little to differentiation between Brachiaria ruziziensis genotypes. Eighty-one genotypes of B. ruziziensis were assessed in completely randomized blocks with three replications. Ten phenotypic characteristics w.. Read More»

Single nucleotide polymorphisms associated with carcass traits in a population of Brahman and Brahman-influenced steers
Authors: A.M. Royer, C. Shivers, D.G. Riley, M.A. Elzo and M.D. Garcia
Brahman cattle are important in tropical regions due to their ability to tolerate excessive heat and parasites. However, Brahman cattle exhibit lower carcass quality characteristics when compared to Bos taurus breeds. The objective of this study was to evaluate potential associations between single nucleotide polymorphisms (SN.. Read More»

Joint analysis of beef growth and carcass quality traits through calculation of co-variance components and correlations
Authors: H.R. Mirzaei, A.P. Verbyla and W.S. Pitchford
A joint growth-carcass model using random regression was used to estimate the (co)variance components of beef cattle body weights and carcass quality traits and correlations between them. During a four-year period (1994-1997) of the Australian “southern crossbreeding project”, mature Hereford cows (N = 581) were ma.. Read More»

An insight in the genetic control and interrelationship of some quality traits in Brassica napus
Authors: S. Ahmad, H.A. Sadaqat, M.H.N. Tahir and F.S. Awan
A study on three leading lines (KN-256, KN-257, and KN-258) of Brassica napus and an approved variety, Punjab-Sarson, was conducted to gain insight into the genetic control of some quality traits using generation mean analysis. Our results showed that additive gene action predominated in the inheritance of oil content and erucic acid in cross KN-256 x KN-.. Read More»

Prediction model of a joint analysis of beef growth and carcass quality traits
Authors: H.R. Mirzaei, A.P. Verbyla and W.S. Pitchford
A joint growth-carcass analysis was conducted to develop equations for predicting carcass quality traits associated with variation in growth path of crossbred cattle. During a four-year period (1994-1997) of the Australian “Southern Crossbreeding Project”, mature Hereford cows (r = 581) were mated to 97 sires of Je.. Read More»

Operational taxonomic units (OTUs) of endophytic bacteria isolated from banana cultivars in the Amazon
Authors: ?. Souza, V.B. Nogueira, J.C. Cruz, N.R. Sousa, A.R.L. Proc?³pio and G.F. Silva
Endophytic microorganisms colonize plants, inhibit the growth of pathogens (by competing for nutrients and/or space), or produce antagonistic substances. Fifty-five endophytic bacteria were isolated from the leaf tissue of the FHIA 18 banana cultivar. Genetic diversity analyses were performed using the enterobacterial repetitive intergenic consensus seque.. Read More»

Polymorphisms in GJA1 and their association with growth traits in chicken
Authors: M. Shahjahan, R.R. Liu, G.P. Zhao, J.J. Zhang, M.Q. Zheng, Q.H. Li and J. Wen
This study aimed to screen single nucleotide polymorphisms (SNPs) in the chicken gap junction protein alpha 1 (GJA1) gene, and to investigate their association with five growth traits measured in 269 chickens encompassing Chinese indigenous Beijing-You (BJY) and commercial Cobb broiler (CB) populations. Four variants were detected in the chicken GJA1 gene.. Read More»

Comparative quantitative trait locus mapping of maize flowering-related traits in an F2:3 and recombinant inbred line population
Authors: Y.H. Liu, Q. Yi, X.B. Hou, X.G. Zhang, J.J. Zhang, H.M. Liu,Y.F. Hu and Y.B. Huang
Flowering-related traits in maize are affected by complex factors and are important for the improvement of cropping systems in the maize zone. Quantitative trait loci (QTLs) detected using different materials and methods usually vary. In the present study, 266 maize (Zea mays) F2:3 families and 301 recombinant inbred lines (RI.. Read More»

Association of genetic variations in the ACLY gene with growth traits in Chinese beef cattle
Authors: M.N. Li, X. Guo, P.J. Bao, X.Y. Wu, X.Z. Ding, M. Chu, C.N. Liang and P. Yan
ATP citrate lyase (ACLY) is the primary enzyme responsible for the synthesis of cytosolic acetyl-CoA, which is a key precursor of both fatty acid and mevalonate synthesis pathways. Genetic variation of the ACLY gene may influence multiple traits associated with animal production. Here, we identified three non-synonymous mutati.. Read More»
