The Cyclotella cryptica CCMP332 genome sequence and gene models have not been determined by the JGI, but were downloaded from CoGe on October 24, 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 16980 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 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 the genes.

The following text is modified from Traller et al. at UCLA:

Cyclotella cryptica is a marine photosynthetic diatom originally isolated from West Tisbury Great Pond, Martha's Vineyard, Massachusetts USA in 1956 by R. Guillard. It was a featured species in the US Department of Energy's Aquatic Species Program as a suitable strain for large-scale production of biofuel from microalgae. The clone of C. cryptica that was chosen for genome sequencing is publicly available from Bigelow National Center for Marine Algae and Microbiota under the identifier CCMP 332. The genome of this oleaginous diatom was sequenced to identify the genetic traits that enable substantial accumulation of triacylglycerol, a precursor to biofuel.
