Ensembl Genomes is a portal that provides integrated access to genome-scale data for non-vertebrate species. It was developed using the Ensembl genome annotation and visualization platform. It consists of sub-portals for bacteria, protists, fungi, plants and invertebrate metazoa that complement the vertebrate genomes available in Ensembl. It provides graphical views of genomes and genes using the Ensembl genome browser software. Data is retrieved through interfaces like BioMart and APIs that access relational databases describing genomic features, sequences and identifiers. Tools like the Assembly Converter and Variant Effect Predictor are also available.
