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.
Study Finding Erroneous Protein-Protein Interactions in Curated Databases Stirs Debate
The study's authors said they have been overwhelmed by reactions to their finding that curation of protein-protein interaction experiments "can be error-prone and possibly of lower quality than commonly assumed."
