The European robin and Turtle dove have had their genetic codes sequenced and assembled for the first time by scientists at the Wellcome Sanger Institute and their collaborators. The genomes, completed today (21 December) will enable researchers to explore the genetic switches controlling bird migration and give insight into the magneto receptors that help robins 'see' the Earth's magnetic fields for navigation. The Turtle dove genome will help conservation efforts to save one of the UK's fastest declining bird species.
European robins live throughout Europe, Russia and western Siberia. While most British robins reside in the UK over winter, some birds will migrate to southern Europe to overwinter in warmer climates. Simultaneously in winter, migrant robins from Scandinavia, continental Europe and Russia head to the UK to avoid the harsh weather back home.
Turtle - Migrate - Breeding - Grounds - Europe
Turtle doves also migrate, visiting their breeding grounds in Europe and spending the winter months in Africa. However, since 1995, 94 per cent of Turtle doves have been lost and there are fewer than 5,000 breeding pairs left in the UK. The Turtle dove is the UK's fastest-declining bird species, and as a result, they are listed as vulnerable on the International Union for Conservation of Nature (IUCN) Red List.
Migration patterns and behaviours vary across species, but also within species. Similarly, environmental pressures such as disease and limited food resources affect various bird species differently. To fully understand the genetic components of complex traits, such as migration and breeding, the whole genetic code must be read and analysed.
European - Robin - Turtle - Genomes - Sanger
The European robin and Turtle dove's genomes were read by the Sanger Institute and its partners, in celebration of Sanger's 25th anniversary.
Collaborators at the University of Lincoln sent robin and Turtle dove samples to the Sanger Institute near Cambridge. The sequencing teams extracted DNA from the samples and used PacBio SMRT Sequencing...
