Polymorphisms in the melatonin receptor gene promoter and their associations with fertility characteristics in buffalo herd in Eastern Amazon

Buffalo production is spreading globally because of its economic advantage. Then, it has become necessary to improve the reproductive and productive efficiency of these animals, as well as to look for genetic factors that increase this efficiency. The objectives of this study were to characterize the promoter region of the melatonin 1A receptor gene (MTRN1A), to det.. Read More»

Buffalo farming in Brazil is increasing, as is the challenge of identifying molecular markers that will improve productivity. Therefore, the aim of this study was to analyze single nucleotide polymorphisms of the receptor gene for the hormone melatonin in buffaloes from northern Brazil by polymerase chain reactions (PCRs) and restriction fragment length polymorphism..

Genetic polymorphisms in β-defensin II gene in Amazon sheep from Brazil

    B.B. Souza, E.M. Barbosa, J.S.N. Azevedo, J.E.G. Campelo,L.F.S. Rodrigues, L.M.L. Pinheiro, S.C.B Silva, A.S. Schierholt, P.H. Souza, E.C. Gonçalves and E. Silva Filho

The northern region of Brazil produces a large number of sheep, with Pará being the largest sheep breeding state in the region. In the Amazon region, livestock production is a challenge due to the high diversity of pathogens affecting humans and animals. Defensins are antimicrobial peptides acting as a first barrier against micro-organisms and present high va.. Read More»

Novel polymorphism in exon 1 of the melatonin receptor gene unassociated with reproductive characteristics of buffaloes in the Amazon Region

    E.M. Barbosa, B.B. Souza, R.C. Guimarães, J.S.N. Azevedo,E.C. Gonçalves, H.F.L. Ribeiro, S.T. Rolim Filho and E. Silva Filho

The objective of this study was to sequence part of the exon 1 in the melatonin receptor 1A gene (MTRN1A) in buffaloes to detect a novel polymorphism with which to associate reproductive characteristics, such as age at first birth and the interval between births, in buffaloes from the northeastern region of the State of Pará (Brazil). Buffalo hair samples (77.. Read More»
