Computing with phenotypic diversity using semantic descriptions Presentation Transcript

  • 1. Computing with phenotypic diversityusing semantic descriptionsJim Balhoff
  • 2. Phenotypic datahttp://www.linnean-online.org/and a cytoplasmic terminal death domain essential for proteininteractions with signaling adaptor complexes. The flste370fmutation is an A to T transversion at a splice acceptor site,Figure 2. The dominant gene Nkt is phenotypically similar, however complements fls mutants. Nkt homozygotes show complete loss ofscales, teeth and gill rakers resembling the fls phenotype (A–C). Heterozygous Nkt zebrafish show an intermediate phenotype of scale loss andpatterning defect (arrows) while no effect on fin development is seen (D). Heterozygous Nkt also show a dominant effect on the number of teeth(arrows, E) and gill rakers (F), showing deficiencies along the posterior branchial arches and formation of rudimentary rakers along ceratobranchial 1and 2 (arrows, F).

  • 13. Semantic descriptions• Mullins et al. 2012. A revision of Evaniscus (Hymenoptera,Evaniidae) using ontology-based semantic phenotypeannotation. ZooKeys• Balhoff et al. 2013. A semantic model for speciesdescription applied to the ensign wasps (Hymenoptera:Evaniidae) of New Caledonia. Systematic Biology(describes semantics)• Taxonomic descriptions available as RDF in Dryad• http://dx.doi.org/10.5061/dryad.2gd84• http://dx.doi.org/10.5061/dryad.2jd88• Phenoscape is working to provide KB data in RDF
  • 14. Conclusion• Standardize association of character data withphenotype models and referenced organisms• Common model for Phenoscape annotationsand wasp taxonomic descriptions• Character state annotations can denote classesdescribing any semantic model (not only EQ)• Specimen identifiers and a standard model forcollections data in RDF are needed (Darwin-SW, BCO)
