The Nannochloropsis salina CCMP1776 genome sequence and gene models have not been determined by the JGI, but were downloaded from the Los Alamos National Laboratory (LANL) Greenhouse portal on October 31, 2019. All published models are available as ExternalModels. In order to ensure this genome is comparable to those sequenced and annotated by the JGI, we applied standard filters to ExternalModels to produce the initial GeneCatalog. A total of 357 of 8,927 external models were excluded based on one of the following classifications: 1) association with repetitive elements, 2) pseudogenes with internal stop codons, 3) alternative isoforms or overlapping transcript models, 4) alleles on secondary scaffolds, and 5) short models lacking functional annotation. 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.

Nannochloropsis salina CCMP1776

Nannochloropsis salina CCMP1776 (Heterokonta, Ochrophyta, Class Eustigmatophyceae) is from a genus of eukaryotic microalgae. Its high lipid content and halotolerance makes this species an important candidate for biofuel feedstock, maintained in large-volume, outdoor culture.
