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.
Developers Propose SBGN as 'Standard Notation' for Systems Biology Collaboration
SBGN was launched in 2005 as an offshoot of the Systems Biology Markup Language. This week, the project published its first paper describing the standard in Nature Biotechnology and released the first version of three languages that underlie the standard.
