The Pleodorina starrii NIES-4481 genome sequence and gene models were not determined by the Joint Genome Institute (JGI), but were downloaded from NCBI on April 24, 2024. 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 1285 external models were excluded based on one of the following classifications: 1) 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 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.
