Unscrambling the genetics of the chicken's 'blue' egg
Date:8/20/2013

They are the latest foodie fashion and look set to become big business in the baking aisles of all the major supermarkets the blue egg produced by some chickens is prettier and some say tastier and cleaner-breaking than the traditional brown one and now, thanks to scientists from The University of Nottingham, we know what caused the eggs in some breeds to turn this unusual colour.

In a four-year research project just published in the journal, PLOS ONE, the team from the School of Biology, has identified the genetic mutation which first produced the blue egg in native South American chicken, the Mapuche fowl, and their European descendants, Araucana between 200 and 500 years ago. The results could inform future research into agricultural breeding techniques if demand for the blue egg continues to grow.

The scientists used the unique genetic resources conserved by heritage or 'fancy' poultry breeders to identify at fine resolution the exact location of the mutation in the genome in blue egg laying chicken. This work was followed by further genomic study which revealed the genetic cause of the blue coloured egg shell surprisingly an ancient harmless retrovirus in the domestic chicken.

A retrovirus is a virus that, unlike most cellular organisms, carries its genetic blueprint in the form of ribonucleic acid (RNA). It reproduces itself in a host cell using a special enzyme called 'reverse transcriptase' which transcribes RNA into deoxyribonucleic acid (DNA). This makes it possible for genetic material from a retrovirus to become permanently incorporated into the DNA of an infected cell. In this case, the retrovirus' effect was to trigger an accumulation of a green-blue bile pigment called biliverdin in the eggshell as the egg develops in the hen.

Leading the team, BBSRC doctoral research fellow, David Wragg said: "An unexpected find was the unique integration sites for the retrovirus in South American/European and Asi
