Nannochloropsis oceanica CCAP849/10
Nannochloropsis oceanica CCAP849/10 was imaged using a Keyence BZ-X700 with 100x oil immersion PlanApo NA 1.45 objective lens and overlayed with chlorophyll autofluorescence (Cy5) (bandwidths: excitation 620/60, emission 700/75).

The Nannochloropsis oceanica CCAP849/10 genome sequence and gene models were not determined by the Joint Genome Institute (JGI), but were provided by collaborators at Los Alamos National Laboratory (LANL). 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 1,087 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 this genome.

Nannochloropsis oceanica CCAP849/10

Nannochloropsis oceanica is an industrially relevant unicellular microalgal Eugstigmatophyte [1,2]. Molecular protocol development for N. oceanica has indicated successful application of CRISPR/Cas9 genome editing, targeted gene replacement, and transformation capabilities [3-6]. N. oceanica CCAP849/10 was obtained from the Culture Collection of Algae and Protozoa (CCAP) from the United Kingdom and is easily cultivated in f/2 medium.
