The Nannochloris desiccata UTEX 2526 genome sequence and gene models were not determined by the Joint Genome Institute (JGI), but were downloaded from NCBI on Oct 21, 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 734 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 this genome.

Nannochloris desiccata 2526 (Trebouxiophyceae, Chlorophyta) is a clonal isolate of N. desiccata 2437 which was originally found as part of, and regrown from, a desiccated microbial mat collected from a salt marsh in Laguna Figueroa, Baja California (Margulis et al 1988). This isolate is truly axenic and grows well in brackish to marine salinities. N. desiccata was classified as a Chlorella then Mychonastes based on phenotype, however phylogenetic analysis using the sequenced genome shows it to fit in the genus Nannochloris. This strain can be obtained from the UTEX culture collection under the name Chlorella desiccata UTEX 2526. (Description courtesy of Claire Sanders)
