The Chrysochromulina parva Lackey genome sequence and gene models have not been determined by the JGI, but were downloaded from Los Alamos National Laboratory (LANL) Greenhouse portal on October 31, 2019. 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 3347 models and the 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 LANL 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 the genes.

Chrysochromulina sp. are naked (non-coccolithophore) haptophytes that are widely distributed in both fresh-water and marine habitats. This species was isolated from Big Walnut Creek, OH, USA. Chrysochromulina sp. are highly oleaginous, making them of potential interest as a biofuel source.
