Associations of DNA polymorphisms in growth hormone and its transcriptional regulators with growth and carcass traits in two populations of Brangus bulls
Authors: Thomas MG, Enns RM, Shirley KL, Garcia MD, Garrett AJ, and Silver GA
Sequence polymorphisms in the growth hormone (GH) gene and its transcriptional regulators, Pit-1 and Prop-1, were evaluated for associations with growth and carcass traits in two populations of Brangus bulls Chihuahuan Desert Rangeland Research Center (CDRRC, N = 248 from 14 sires) and a cooperating breeding program (COOP, N =..

Responses to selection for milk traits in dairy buffaloes
Authors: L.O. Seno, V.L. Cardoso and H. Tonhati
The aim of the present study was to estimate the index and individual responses to selection for milk (MY), fat (FY) and protein (PY) yields for different breeding goals for two commercial buffalo milk production systems in São Paulo State characterized by: 1) all milk produced is sold to the industry (MILK) and 2) all ..

Acid phosphatase activity distribution in salivary glands of triatomines (Heteroptera, Reduviidae, Triatominae)
Authors: Anhe ACB, Lima-Oliveira APM and Azeredo-Oliveira MTV
Acid phosphatase activity (Gömori technique) in salivary gland cells was investigated in adult insects (males and females) of four species of triatomines: Triatoma infestans, Panstrongylus megistus, Rhodnius neglectus, and Rhodnius prolixus. Binucleated cells with bulky and polyploidy nuclei were detected, with acid phosp.. Read More»

Transcriptional regulation of catabolic pathways for aromatic compounds in Corynebacterium glutamicum
Authors: K. Brinkrolf, I. Brune and A. Tauch
Corynebacterium glutamicum is a gram-positive soil microorganism able to utilize a large variety of aromatic compounds as the sole carbon source. The corresponding catabolic routes are associated with multiple ring-fission dioxygenases and among other channeling reactions, include the gentisate pathway, the protocatechuate and.. Read More»

Phenotypic and genetic correlations for body structure scores (frame) with productive traits and index for CEIP classification in Nellore beef cattle
Authors: Horimoto ARVR, Ferraz JBS, Balieiro JCC and Eler JP
The present study was carried out to estimate both (co)variance components and genetic parameters for frame scores obtained using two methods (FRAME_GMA and FRAME_BIF) as well as phenotypic and genetic correlations with traits such as weaning weight, weight gain from weaning to yearling, scrotal circumference, muscle score, an..

Genetic trend for milk yield in Guzerat herds participating in progeny testing and MOET nucleus schemes
Authors: M.G.C.D. Peixoto, R.S. Verneque, R.L. Teodoro, V.M. Penna and M.L.Martinez
Genetic trends for 305-day milk yield (P305) in Brazilian Guzerat herds under selection were compared. Data from 4898 lactations of 3179 purebred and crossbred cows from various regions of Brazil were used. Milk yield was adjusted for mature age and the contemporary groups were defined as herd and calving year. Genetic paramet.. Read More»

Evaluation of DNA polymorphisms involving growth hormone relative to growth and carcass characteristics in Brahman steers
Authors: V.R. Beauchemin, M.G. Thomas, D.E. Franke2 and G.A. Silver
Associations of DNA polymorphisms in growth hormone (GH) relative to growth and carcass characteristics in growing Brahman steers (N = 324 from 68 sires) were evaluated. Polymorphisms were an Msp-I RFLP and a leucine/valine SNP in the GH gene as well as a Hinf-I RFLP and a histidine/arginine SNP in transcriptional regulators o.. Read More»

Genetic variation of Prochilodus lineatus (Valenciennes, 1836) from ParanÃ?¡, BaÃ?Âa, Miranda, and CorumbÃ?¡ rivers, Brazil
Authors: E. Revaldaves, E. Renesto and J.R. Gold
The curimbatá (Prochilodus lineatus) is one of the migratory species in the Paraná River Basin impacted by the construction of dams. Mitochondrial DNA sequences and random amplified polymorphic DNA (RAPD) fragments were used to investigate genetic variability and geographic structure of five populations of curimb.. Read More»

Characterization of the male-specific lethal 3 gene in the oriental river prawn, Macrobrachium nipponense
Authors: Y.P. Zhang, S.M. Sun, H.T. Fu, X.P. Ge, H. Qiao, W.Y. Zhang, Y.W. Xiong, S.F. Jiang, Y.S. Gong and S.B. Jin
In this study, male-specific lethal 3 homolog (Mnmsl3) was cloned and characterized from the freshwater prawn Macrobrachium nipponense (Crustacea: Decapoda: Palaemonidae) by rapid amplification of cDNA ends. The deduced amino acid sequences of Mnmsl3 showed high-sequence homology to the insect Msl3 and contained a conserved chromatin organization modifier.. Read More»

Determination of ancestral proportions in synthetic bovine breeds using commonly employed microsatellite markers
Authors: H.M.S. Bicalho, C.G. Pimenta, I.K.P. Mendes, H.B. Pena, E.M. Queiroz and S.D.J. Pena
The International Society of Animal Genetics (ISAG) has chosen nine microsatellites (international marker set) as a standard that should be included in all cattle parentage studies. They are BM1824, BM2113, INRA023, SPS115, TGLA122, TGLA126, TGLA227, ETH10, and ETH225. We decided to ascertain whether this microsatellite set co.. Read More»
