$50-million US project to chart cattle genome

Scientists plan to sequence all the genes in cattle, a $50-million US project that may uncover important findings relating to human genes and help fight human disease.

The gene-sequencing project has been touted for its benefits to the beef and dairy industries.

The National Human Genome Research Institute has approved plans to pay half the cost if $25 million is raised. The state of Texas has pledged $10 million, leaving another $15 million to be raised.

Scientists say the bovine genome is similar in size to the genomes of humans and other mammals. Sequencing the genome will allow researchers to identify functions of cattle genes.

"By comparing the human genome with the genomes of different organisms, we can better understand the structure and function of human genes and thereby develop new strategies in the battle against human disease," NHGRI director Dr. Francis Collins said in a statement.

"The more genomes we have, the more powerful this tool becomes."

The information could help producers selectively breed cattle for tenderness and marbling, as well as help animals to become more disease-resistant and less reliant on antibiotics, scientists said.

Researchers in Texas hope to begin sequencing the cattle genome in September.

The complete human genome sequence is expected next month. Scientists have already sequenced and analysed the genomes of several model organisms, including baker's yeast, the roundworm and the laboratory mouse.
