Nuclear gene indicates coat-color polymorphism in mammoths.
نویسندگان
چکیده
By amplifying the melanocortin type 1 receptor from the woolly mammoth, we can report the complete nucleotide sequence of a nuclear-encoded gene from an extinct species. We found two alleles and show that one allele produces a functional protein whereas the other one encodes a protein with strongly reduced activity. This finding suggests that mammoths may have been polymorphic in coat color, with both dark- and light-haired individuals co-occurring.

Polymorphisms in Melanocortin Receptor 1 Gene in Goat Breeds: A Window for Coat Color Controling Mechanism
The broad goal of this research was to examine the nature of the Melanocortin receptor 1 (MC1R) locus on the coat color phenotype of seven goat breeds with different color coat. Blood samples were collected from five Iranian indigenous (Khalkhal, Markhor, Naeini, Najdi and Tali) and two exotic (Cashmere and Saanen) goat breeds. Polymerase chain reaction restriction fragment length polymorphism ...
متن کاملPopulation-level genotyping of coat colour polymorphism in woolly mammoth (Mammuthus primigenius)
Patterns in the spatial or temporal distribution of genotypes may be indicative of natural selection. Previous work on the woolly mammoth melanocortin-1 receptor (Mc1r) gene identified three polymorphic positions that suggest Pleistocene populations may have harboured both lightand dark-haired mammoths (Rompler et al., 2006, 313: 62). Here, we extend this work and present the first populationle...
متن کاملAnalysis of agouti signaling protein (ASIP) gene polymorphisms and association with coat color in Tibetan sheep (Ovis aries).
Tibetan sheep, an indigenous breed, have a wide variety of phenotypes and a colorful coat, which make this breed an interesting model for evaluating the effects of coat-color gene mutations on this phenotypic trait. The agouti signaling protein (ASIP) gene is a positional candidate gene, as was inferred based on previous study. In our research, ASIP gene copy numbers in genomic DNA were detecte...
متن کاملMC1R, KIT, IGF2, and NR6A1 as markers for genetic differentiation in Thai native, wild boars, and Duroc and Chinese Meishan pigs.
Mutations in melanocortin 1 receptor (MC1R) gene and v-kit Hardy-Zuckerman 4 feline sarcoma viral oncogene homolog (KIT) gene have been shown to affect coat color patterns in pigs. Additional functional marker genes, such as insulin like growth factor-2 (IGF2) and orphan nuclear receptor, germ cell nuclear factor (NR6A1), have been described for variations in factors such as fat deposition, lit...
متن کاملA noncoding melanophilin gene (MLPH) SNP at the splice donor of exon 1 represents a candidate causal mutation for coat color dilution in dogs.
Coat color dilution in several breeds of dog is characterized by a specific pigmentation phenotype and sometimes accompanied by hair loss and recurrent skin inflammation, the so-called color dilution alopecia or black hair follicular dysplasia. Coat color dilution (d) is inherited as a Mendelian autosomal recessive trait. In a previous study, MLPH polymorphisms showed perfect cosegregation with...
