Special Online Collection: The Sea Urchin Genome

Jump to features in special collection:

The Sea Urchin GenomeThis week, Science and its online companion site the Signal Transduction Knowledge Environment (STKE) describe the sequencing of the genome of the sea urchin Strongylocentrotus purpuratus and initial insights obtained from the sequence. In Science, a Research Article and Report detail the sea urchin genome and transcriptome, while Review and Perspective articles explore the ecological role of purple sea urchins, genomic insights into their immune systems, and paleogenomic studies of sea urchins and their spiny skinned relatives. Online, an interactive poster and podcast segment highlight the contributions of sea urchins to fundamental principles of cell biology, developmental biology and gene regulation. And articles in STKE look at the signaling mechanisms involved in sea urchin embryogenesis. (Note: All articles in the Science sea urchin special section, as well as the interactive poster and podcast, are free to all site visitors.)
