Welcome to SmedGD v1.3.14 - now even SMED-ier.
Please let us know what you think.


Some of the new features:

  • A new version of Gbrowse with pop-up balloons and other improvements (version 1.69)
  • A new data track with PDB homology of the MAKER annotations. Pop-up bubbles have structual images.
  • Two new data tracks with gene annotations from Nikolaus Rajewsky and Marc Friedlaender at the MDC.
  • A new data track aligning the EST contigs with SPA
  • Improvements to the miRNA data track
  • Renaming and rearrangement of several of the data tracks.


Planarians are free-living (non-parasitic) freshwater organisms possessing derivatives of all three germ layers (i.e., ectoderm, mesoderm and endoderm). These animals are renowned for their developmental plasticity and have attracted the attention of generations of biologists (http://planaria.stowers.org).


Among all flatworm species studied thus far, the planarian Schmidtea mediterranea is rapidly emerging as a key model organism for the study of regeneration, tissue homeostasis and stem cell biology. The Schmidtea mediterranea Genome Database (SmedGD) is a GMOD compliant database that integrates in a single web-accessible portal all available data associated with the planarian genome, including predicted and annotated genes, ESTs, protein homologies, gene expression patterns and RNAi phenotypes.
