A polar bear phylogeny based on hundreds of mitochondrial DNA sequences from polar and brown bear samples from as far back as about 120,000 years ago hints at a shared maternal ancestry for modern polar bears and Irish brown bears.

Using nuclear and mitochondrial genome sequencing and genotyping, researchers have garnered clues about the genetic diversity and structure within Tasmanian devil populations and gained insights into the contagious cancer threatening devils in the wild.

The funding will support studies of Holstein cows to develop genomic characteristics for boosting milk production efficiency.

The project's goal is to sequence the genomes of 5,000 insects and other arthropods to gain a better understanding of insect biology and better manage those that pose threats to human health, the food supply, and economic security.

By comparing genetic and gene expression patterns in African cattle breeds that are relatively sensitive or resistant to Trypanosoma congolense infection, researchers have identified genes that they suspect may contribute to trypanotolerance in cattle.

A group of partners from the three countries will share genomic evaluation data for breeding and boosting the total number of cattle being examined.

The funding will be used for purchasing equipment and operating costs of the new laboratory, which will be a spinout of the University of Alberta's Livestock Gentec Program.

The Technology Strategy Board and BBSRC will provide more than £4.5 million ($7.3 million) for 11 research and development projects using genomics-based technologies.

Researchers from the University of Lethbridge will develop new strategies to "mitigate the shedding" of E. coli O157:H7 and new compounds to control the pathogen.

By sequencing the genome and transcriptome of the leaf-cutter ant Atta cephalotes, researchers are learning about the genetic features contributing to the ant's obligate symbiotic relationship with the fungus it farms.
