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.
PacBio Reveals Commercial Specs; Initial Focus on Long Reads, Short Runs, Low Experiment Cost
While several competing sequencing platforms are focusing on large numbers of reads and low cost per base, PacBio is initially emphasizing the comparatively long read lengths, short run time, low cost per experiment, and different applications that its single-molecule analysis system will provide.
