Xenopus ANatomical entity (XAN): embryo
Like Gene Ontology (GO), biomedical ontology such as phenotype ontology classifies and organizes gene-mutant/null phenotypic information from the very general at the top to more specific terms in the directed acyclic graph (DAG) by viewing an individual term as a node and its relations to parental terms (allowing for multiple parents) as directed edges. To navigate this hierarchy, we display all parental phenotypic terms to the current phenotypic term of interest ordered by their shortest distances to the current term. Also, only direct children phenotypic terms of the current phenotypic term are listed. Biomedical ontologies we have incorporated are as follows:
- Worm Phenotype (WP) Ontology WP classifies and organizes phenotype descriptions for C. elegans and other nematodes. Using it, WormBase provides primary resource for phenotype annotations for C. elegans.
- Xenopus Anatomy (XA) Ontology XA represents the lineage of tissues and the timing of development for frogs (Xenopus laevis and Xenopus tropicalis). It is used to annotate Xenopus gene expression patterns and mutant and morphant phenotypes.
- UniProtKB KeyWords (KW) Ontology Keywords in UniProtKB are controlled vocabulary, providing a summary of the entry content and are used to index UniProtKB/Swiss-Prot entries based on 10 categories (the category "Technical term" being excluded here). Each keyword is attributed manually to UniProtKB/Swiss-Prot entries and automatically to UniProtKB/TrEMBL entries (according to specific annotation rules).
- CTD Diseases (CD) Ontology CD is MEDIC disease vocabulary that is modified by CTD from the "Diseases" [C] branch of Medical Subject Headings (MeSH), combined with genetic disorders from the Online Mendelian Inheritance in OMIM database.
- CTD Chemicals (CC) Ontology CC is chemical vocabulary that is adapted by CTD from the "Chemicals and Drugs" category and Supplementary Concept Records of Medical Subject Headings (MeSH, a hierarchical vocabulary used to index articles for MEDLINE/PubMed).
