ready Phenotypic QualiTy Ontology

Abbreviation: PATO

General Information
PATO is an ontology of phenotypic qualities, intended for use in a number of applications, primarily phenotype annotation. This ontology can be used in conjunction with other ontologies such as GO or anatomical ontologies to refer to phenotypes.

NIF maintains the largest searchable collection of neuroscience data, the largest catalog of biomedical resources, and the largest ontology for neuroscience on the web.

The Zebrafish Information Network
The Zebrafish Information Network, ZFIN, serves as the primary community database resource for the laboratory use of zebrafish. We develop and support integrated zebrafish genetic, genomic, developmental and physiological information and link this information extensively to corresponding data in other model organism and human databases.

Open Targets
Open Targets is a data integration platform for access to and visualisation of potential drug targets associated with disease. Each drug target is linked to a disease using integrated genome-wide data from a broad range of data sources.

A resource providing data on bioentities and their associated ontology terms for Plant Biology. The database provides access to ontology-based annotations of genes, phenotypes and germplasms from about 90 plant species. A number of internal and external ontologies are used to annotate the biological data available from this resource.

Alliance of Genome Resources
The primary mission of the Alliance of Genome Resources (the Alliance) is to develop and maintain sustainable genome information resources that facilitate the use of diverse model organisms in understanding the genetic and genomic basis of human biology, health and disease.

OBO Foundry
The Open Biological and Biomedical Ontology (OBO) Foundry is a collective of ontology developers that are committed to collaboration and adherence to shared principles. The mission of the OBO Foundry is to develop a family of interoperable ontologies that are both logically well-formed and scientifically accurate. To achieve this, OBO Foundry participants voluntarily adhere to and contribute to the development of an evolving set of principles including open use, collaborative development, non-overlapping and strictly-scoped content, and common syntax and relations, based on ontology models that work well, such as the Gene Ontology (GO). The OBO Foundry is overseen by an Operations Committee with Editorial, Technical and Outreach working groups.

RIKEN Arabidopsis Genome Encyclopedia II
RARGE II provides basic information about the Arabidopsis genome, such as information related to cDNA sequences and transposon insertion mutants. To create it, publicly available information for a total of 66,209 Arabidopsis mutant lines was used, including loss-of-function (RATM and TARAPPER) and gain-of-function (AtFOX and OsFOX) lines, as well as phenotype data gained through the mapping of descriptions onto Plant Ontology (PO) and Phenotypic Quality Ontology (PATO) terms.

The LEAFDATA resource collects information from primary research articles focusing on Arabidopsis leaf growth and development. The result section of selected papers is manually annotated and organized into distinct categories. Text fragments of the manuscripts are displayed with links to the original papers on PubMed.

Encyclopedia of Life
The Encyclopedia of Life (EOL) is a collaborative encyclopedia to describe all known living species. It identifies sources of biodiversity knowledge that are legally and practically shareable; integrates them with other sources and adds metadata; provides searching and other services; and collaborates with other projects to support data sharing.
