Fighting sheep worms with genomics

18.05.2004


Leading-edge technology is being used by two CSIRO Livestock Industries’ research teams to identify genes that enable sheep to resist intestinal parasites.

The discovery of such genes could lead to new products, control strategies, and markers to identify superior animals in selective breeding programs, which will substantially improve the overall health and welfare of the national flock.

With support from Meat and Livestock Australia (MLA) and Australian Wool Innovation (AWI) through their joint $30m Sheep Genomics Program, the Brisbane and Armidale-based teams will use modern genetic technologies - such as microarrays and the real-time polymerase chain reaction (PCR) - to determine the expression level of genes in worm-resistant and susceptible sheep.



"CSIRO Livestock Industries in Armidale has a long history of research into resistance to nematodes (worms), and has selectively bred nematode-resistant flocks of sheep that facilitate both projects," says Brisbane team leader, Dr Aaron Ingham.

"The Brisbane and Armidale teams will work closely together to conduct detailed complementary molecular genetic analyses on sheep produced from these flocks. The Armidale team will also provide the necessary parasitological and immunological expertise for both projects," he says.

The Brisbane team will use real time PCR to screen a number of ’candidate’ genes that are known to be involved in disease responsiveness and resistance, tissue regeneration, wound repair, appetite and basic physiology.

The Armidale team will use microarray technology to undertake a broad, unbiased screen of thousands of genes, to identify those responsible for nematode resistance.

Gene expression that is consistently different between resistant and susceptible animals will be targeted for further study.

Im Focus: Giant Magnetic Fields in the Universe

Astronomers from Bonn and Tautenburg in Thuringia (Germany) used the 100-m radio telescope at Effelsberg to observe several galaxy clusters. At the edges of these large accumulations of dark matter, stellar systems (galaxies), hot gas, and charged particles, they found magnetic fields that are exceptionally ordered over distances of many million light years. This makes them the most extended magnetic fields in the universe known so far.

The results will be published on March 22 in the journal „Astronomy & Astrophysics“.

Galaxy clusters are the largest gravitationally bound structures in the universe. With a typical extent of about 10 million light years, i.e. 100 times the...

Im Focus: Tracing down linear ubiquitination

Researchers at the Goethe University Frankfurt, together with partners from the University of Tübingen in Germany and Queen Mary University as well as Francis Crick Institute from London (UK) have developed a novel technology to decipher the secret ubiquitin code.

Ubiquitin is a small protein that can be linked to other cellular proteins, thereby controlling and modulating their functions. The attachment occurs in many...

Im Focus: Polymer-coated silicon nanosheets as alternative to graphene: A perfect team for nanoelectronics

Silicon nanosheets are thin, two-dimensional layers with exceptional optoelectronic properties very similar to those of graphene. Albeit, the nanosheets are less stable. Now researchers at the Technical University of Munich (TUM) have, for the first time ever, produced a composite material combining silicon nanosheets and a polymer that is both UV-resistant and easy to process. This brings the scientists a significant step closer to industrial applications like flexible displays and photosensors.

Im Focus: Researchers Imitate Molecular Crowding in Cells

Enzymes behave differently in a test tube compared with the molecular scrum of a living cell. Chemists from the University of Basel have now been able to simulate these confined natural conditions in artificial vesicles for the first time. As reported in the academic journal Small, the results are offering better insight into the development of nanoreactors and artificial organelles.
