The Zebrafish Information Network: the zebrafish model organism database.

The Zebrafish Information Network (ZFIN; http://zfin.org) is a web based community resource that implements the curation of zebrafish genetic, genomic and developmental data. ZFIN provides an integrated representation of mutants, genes, genetic markers, mapping panels, publications and community resources such as meeting announcements and contact information. Recent enhancements to ZFIN include (i) comprehensive curation of gene expression data from the literature and from directly submitted data, (ii) increased support and annotation of the genome sequence, (iii) expanded use of ontologies to support curation and query forms, (iv) curation of morpholino data from the literature, and (v) increased versatility of gene pages, with new data types, links and analysis tools.

GSD: a genetic screen database.

The systematic assignment of gene function to a sequenced genome is one of the outstanding challenges in the post-genomic era. Large-scale systematic mutagenesis screens are important tools for reaching this goal. Here we describe GSD, a software package that allows storage and integration of data from genetic screens. GSD was initially developed for a large-scale F3 mutagenesis screen for developmental mutants of medaka (Oryzias latipes). The version presented here supports a wide range of different screens (mutagenesis, RNAi, morpholinos, transgenesis and others) using different organisms. Data are stored in a relational database and can be made accessible through web interfaces. Researchers can enter data describing their screened embryos: They can track statistics, submit images and describe the resulting phenotypes using a phenotype classification ontology. We developed a fish phenotype classification ontology of medaka and zebrafish for this software package and made it available to the public. In addition, a list of genetic lines resulting from each screen can be generated. These lines (mutant alleles, transgenic lines) can be described and categorized in the same ways as the screened individuals. Raw data from the screen can be integrated to describe these lines. A query module that searches this list can be used to publish the screen results on the Internet. A test version is available at and the software can be downloaded from this site.

The Zebrafish Information Network (ZFIN): the zebrafish model organism database.

The Zebrafish Information Network (ZFIN) is a web based community resource that serves as a centralized location for the curation and integration of zebrafish genetic, genomic and developmental data. ZFIN is publicly accessible at http://zfin.org. ZFIN provides an integrated representation of mutants, genes, genetic markers, mapping panels, publications and community contact data. Recent enhancements to ZFIN include: (i) an anatomical dictionary that provides a controlled vocabulary of anatomical terms, grouped by developmental stages, that may be used to annotate and query gene expression data; (ii) gene expression data; (iii) expanded support for genome sequence; (iv) gene annotation using the standardized vocabulary of Gene Ontology (GO) terms that can be used to elucidate relationships between gene products in zebrafish and other organisms; and (v) collaborations with other databases (NCBI, Sanger Institute and SWISS-PROT) to provide standardization and interconnections based on shared curation.
