It is the leading website and database of Drosophila genes and genomes. FlyBase curates a variety of data from published biological literature, including phenotype, gene expression, interactions (genetic and physical), gene ontology (GO) information and many others. These data are organized in ∼31 different data-type reports such as the Gene Report or the Allele Report. The range of data we provide increases and changes as new types of data become available. Whether you are using the fruit fly Drosophila melanogaster as an experimental system or wish to understand Drosophila biological knowledge in relation to human disease or to other model systems, FlyBase can help you successfully find the information you are looking for.
