Sequencing and Analysis of the Hydra Genome
Chapman, Kirkness et al., Nature
An international research collaboration reports their sequencing and analysis of the Hydra magnipapillata genome, and compare it to the genomes of several other organisms. "The Hydra genome has been shaped by bursts of transposable element expansion, horizontal gene transfer, trans-splicing, and simplification of gene structure and gene content that parallel simplification of the Hydra life cycle," the authors write. They team suggests that comparisons of the Hydra genome to the reported sequences of other animals have helped them to elucidate the evolution of several of the organism's characteristics.
African Dog Genetics Suggest New View of Domestication Needed
August 04, 2009
An international research team led by investigators at Cornell University has discovered that African village dogs are as genetically diverse as East Asian dogs, leading them to question the assertion that dogs were domesticated in Asia.
