  1. Plant structure and growth stage ontologies to describe phenotypes and gene expression in angiosperms Pankaj Jaiswal Cornell University www.plantontology.org

  2. Vocabulary examples Different resources try to control their vocabulary. However there is no standardized format, definition and often no equivalence (cross reference) to another resource. The vocabularies are organized in a simple tree format….??

  3. Plant structure cellroot guard celltrichoblastroot hairroot cortex is a is a i i part of is a p i Plant Structure +-- cell | +-- guard cell | +-- root hair | +-- trichoblast | +-- root hair +-- root +-- root cortex +-- trichoblast +-- root hair • Statement looks like • Trichome, root hair, root cortex are part of root • Trichoblast, root hair and guard cell are type of cell • Root hair develops from trichoblast • Cell and root are types of plant structure i i i i D i p p D term to term relationship develops from D

  4. Inflorescence terms were synonymized Annual Review of Plant BiologyVol. 53: 399-419 Flower terms have children with is_a and sensu Genome Biology 2000, 1:reviews1015.1-1015.4 Plant and Cell Physiology 2005 46(1):69-78

  5. BBCH model Rice Arabidopsis Temporal aspect POC

  6. Temporal Anatomy

  7. Use of synonyms to search for species specific stage

  8. Objectives met • Ontologies released with an emphasis on rice, maize and Arabidopsis • Plant structure • Plant growth and plant part developmental stages • More than 5400 associations to genes and stocks from rice, maize and Arabidopsis. • First publication, Jaiswal et al. Comp. and Funct. Genomics 2006 (in press) • Users meeting in PAG 2005 and PAG 2006 Future plans • Extend vocabularies to include terms required by other cereals, legumes (soybean and Medicago), Solanaceae (tomato), tree (Populus) for functional annotation of phenotypes and gene expression • Resolve the inherent problems faced on multiplicative usage of terms with similar structures under sensu nodes. • Grant renewal and maintenance
