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.
Independent Studies Use Illumina GA To Sequence Three Human Genomes
The three studies — analyzing the genomes of a HapMap sample of African origin, a Han Chinese individual, and a leukemia patient — are the first published genomes sequenced on the Illumina Genome Analyzer and increased the number of peer-reviewed individual human genomes from two to five.
