We will have a brief downtime on Tuesday May 28 between 8:45 and 9:30 am PDT due to network equipment maintenance.

The Geosiphon pyriformis genome sequence and gene models were not determined by the Joint Genome Institute (JGI), but were provided by Nicolas Corradi and Mathu Malar C at the University of Ottawa. In order to ensure this genome is comparable to those sequenced by the JGI, we applied filters to remove if present: 1) transposable elements, 2) pseudogenes, 3) alternative transcripts and overlapping models, 4) alleles on secondary scaffolds and 5) unsupported short models. This resulted in the removal of 11,987 models from G. pyriformis and the generation of the FilteredModels1 gene track. All provided models are available in the ExternalModels track. Please note that this copy of the genome is not maintained by the original authors and is therefore not automatically updated. In order to allow comparative analyses with other fungal genomes sequenced by the JGI, a copy of this genome is incorporated into MycoCosm. The JGI Annotation Pipeline was used to add functional annotation to this genome.

Geosiphon is the only fungus that forms endocyanosis with a cyanobacterium called Nostoc, and is an offshoot of the Arbuscular Mycorrhizal Fungi (AMF) phylogenetic tree. This organism is found in central Europe, but its genome biology is not understood. This strain of Geosiphon was isolated from a fields in Germany, and sequenced using Illumina.
