Ensembl Genomes is developed by EMBL-EBI and is powered by the Ensembl software system for the analysis and visualisation of genomic data. For details of our funding please click here.

The first Rhizaria genome

Ensembl Protists now includes a Rhizaria genome, Bigelowiella natans. Rhizaria as a whole, is one of the most poorly understood supergroups of eukaryotes with an intreasting mix of photosynthetic and non-photosynthetic organisms. The Rhizaria genomes help us to understand the process of secondary endosymbiosis and its impact on the molecular and cell biology of secondary plastid-containing algae and pathogens where the plastids are lost. Bigelowiella natans belongs to the photosynthetic sub-group called chlorarachniophytes, they still possess the nucleus (nucleomorph) and cytoplasm of their algal endosymbionts in a highly reduced and simplified form.

Along with the rhizaria genome, Ensembl Protists now also have six plant pathogen genomes of the genus Pythium, a fungal-like organism, resulted from the secondary endosymbiotic event but lost its ablitly to do photosynthesis.


EMBL-EBI and Rothamsted Research have jointly released the PhytoPath portal, a joint project bringing together Ensembl Genomes with PHI-base, a community-curated resource describing the role of genes in pathogenic infection. PhytoPath provides access to genomic and phentoypic data from fungal and oomycete plant pathogens, and has enabled a considerable increase in the coverage of phytopathogen genomes in Ensembl Fungi and Ensembl Protists.

PhytoPath also provides enhanced searching of the PHI-base resource as well as the fungi and protists in Ensembl Genomes.


PhytoPath is funded by the BBSRC.
