Status
The Ostreobium quekettii SAG 6.99 genome assembly and gene models have not been determined by the JGI, but were downloaded from NCBI on November 30, 2022. 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 1184 models from O. quekettii and generation of the FilteredModels1 (GeneCatalog) gene track. All published models are available in the ExternalModels track. Please note that this copy of the genome is not maintained by NCBI and is therefore not automatically updated. In order to allow comparative analyses with other algal genomes sequenced by the JGI, a copy of this genome is incorporated into PhycoCosm. The JGI Annotation Pipeline was used to add functional annotation to this genome.

Note: This genome was found to have low BUSCO assembly completeness, but has been added to PhycoCosm because of its unique position as the first sequenced Ostreobineae genome.
