Insights into the alpaca skin transcriptome in relation to fibre colour
MetadataShow full item record
Through a combination of chemical and genomic data this study has demonstrated that "brown" alpacas are predominantly pheomelanic, and are similar to bay horses in colour phenotype. RNAseq was used to analyse colour genes the alpaca skin-transcriptome, and has provided the first annotation of the alpaca (vicPac2) genome which is not based on in-silico gene-prediction. Upregulated expression of the agouti gene results in white and diluted colour phenotypes in alpacas.

Munyard, Kylie (2013)This RIRDC report describes the research conducted as part of the alpaca colour genetics project to identify the genes involved in the inheritance of white colour in alpacas. Three approaches were used (Mendelian, physical ...
Polymorphisms Detected in the Tyrosinase and MATP (SLC45A2) Genes Did Not Explain Coat Colour Dilution in a Sample of Alpaca (Vicugna pacos)Cransberg, R.; Munyard, Kylie (2009)The molecular basis of inheritance of alpaca fibre colour is poorly understood. However, colour dilution genes are anticipated to be causing a major effect on alpaca fibre colour. Candidate genes for dilutions included ...
Polymorphisms detected in the tyrosinase and matp (slc45a2) genes did not explain coat colour dilution in a sample of Alpaca (Vicugna pacos)Cransberg, R.; Munyard, Kylie (2011)The molecular basis of the inheritance of alpaca fibre colour is poorly understood. It is likely that colour dilution is having an influence on alpaca fibre colour, with all primarily pheomelanic animals differing mainly ...
