Genetic variation of the bronze locus (MC1R) in turkeys from Southern Brazil

Autor: Josmael Corso, Diego Hepp, Mônica C. Ledur, Jane O. Peixoto, Nelson J. R. Fagundes, Thales R. O. Freitas

Publikováno v: Genetics and Molecular Biology, Vol 40, Iss 1, Pp 104-108 (2017)

Abstract Domestic turkeys present several color phenotypes controlled by at least five genetic loci, but only one of these has been identified precisely: the bronze locus, which turned out to be the melanocortin-1 receptor (MC1R) gene. MC1R variation

Divergent genetic mechanism leads to spiny hair in rodents.

Autor: Gislene L Gonçalves, Renan Maestri, Gilson R P Moreira, Marly A M Jacobi, Thales R O Freitas, Hopi E Hoekstra

Publikováno v: PLoS ONE, Vol 13, Iss 8, p e0202219 (2018)

Spines, or modified hairs, have evolved multiple times in mammals, particularly in rodents. In this study, we investigated the evolution of spines in six rodent families. We first measured and compared the morphology and physical properties of hairs

Pleistocene climatic oscillations in Neotropical open areas: Refuge isolation in the rodent Oxymycterus nasutus endemic to grasslands.

Autor: Willian T Peçanha, Sergio L Althoff, Daniel Galiano, Fernando M Quintela, Renan Maestri, Gislene L Gonçalves, Thales R O Freitas

Publikováno v: PLoS ONE, Vol 12, Iss 11, p e0187329 (2017)

Pleistocene climatic oscillations favoured the expansion of grassland ecosystems and open vegetation landscapes throughout the Neotropics, and influenced the evolutionary history of species adapted to such environments. In this study, we sampled popu

Van der Waals materials as dielectric layers for tailoring the near-field photonic response of surfaces

Autor: D. Grasseschi, D. A. Bahamon, F. C. B. Maia, I. D. Barcelos, R. O. Freitas, C. J. S. de Matos

Publikováno v: Optics express. 30(1)

Epsilon near-zero photonics and surface polariton nanophotonics have become major fields within optics, leading to unusual and enhanced light-matter interaction. Specific dielectric responses are required in both cases, which can be achieved, e.g., v

DNA barcoding of sigmodontine rodents: identifying wildlife reservoirs of zoonoses.

Autor: Lívia Müller, Gislene L Gonçalves, Pedro Cordeiro-Estrela, Jorge R Marinho, Sérgio L Althoff, André F Testoni, Enrique M González, Thales R O Freitas

Publikováno v: PLoS ONE, Vol 8, Iss 11, p e80282 (2013)

Species identification through DNA barcoding is a tool to be added to taxonomic procedures, once it has been validated. Applying barcoding techniques in public health would aid in the identification and correct delimitation of the distribution of rod

Molecular evolution of the melanocortin 1-receptor pigmentation gene in rodents

Autor: G L, Gonçalves, V R, Paixão-Côrtes, T R O, Freitas

Publikováno v: Genetics and molecular research : GMR. 12(3)

Adaptive variation in the melanocortin 1-receptor gene (MC1R), a key locus in melanogenesis, has been identified in some species of rodents. However, in others, MC1R has no causative role in pigmentation phenotypes despite their coat color variation.
