Última Genetic variation of the bronze locus (MC1R) in turkeys from Southern Brazil Genet. Mol. Biol. Corso,Josmael; Hepp,Diego; Ledur,Mônica C.; Peixoto,Jane O.; Fagundes,Nelson J. R.; Freitas,Thales R. O.. 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 is important for breeders interested in maintaining or developing different color varieties. In this study, we sequenced most of the MC1R gene from 16 White Holland (the main commercial turkey variety) and 19 pigmented turkeys from southern Brazil with two purposes. The first was to describe the MC1R diversity in White Holland turkeys, which may serve as reservoirs of genetic diversity at this locus. The second was to test whether the traditional color classification used by Brazilian breeders is related to...

Mol. Biol. Corso,Josmael; Gonçalves,Gislene L.; Freitas,Thales R.O. de. In reptiles, dorsal body darkness often varies with substrate color or temperature environment, and is generally presumed to be an adaptation for crypsis or thermoregulation. However, the genetic basis of pigmentation is poorly known in this group. In this study we analyzed the coding region of the melanocortin-1-receptor (MC1R) gene, and therefore its role underlying the dorsal color variation in two sympatric species of sand lizards (Liolaemus) that inhabit the southeastern coast of South America: L. occipitalis and L. arambarensis. The first is light-colored and occupies aeolic pale sand dunes, while the second is brownish and lives in a darker sandy habitat. We sequenced 630 base pairs of MC1R in both species. In total, 12 nucleotide polymorphisms were... Tipo: Info:eu-repo/semantics/article Palavras-chave: Adaptation; Body color; Crypsis; Liolaemidae; Pigmentation genes.
