The Conticribra weissflogii CCMP 1336 genome sequence and gene models were not determined by the Joint Genome Institute (JGI), but were provided by the authors, Linzhou Li et al. 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 3,292 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 the authors 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.

Conticribra weissflogii (previously, Thalassiosira weissflogii) is a centric diatom belonging to the family Thalassiosiraceae. Like other diatoms, C. weissflogii has a silicified cell wall, and it has been suggested that chitin may also be an important cell wall component. The genome was sequenced to investigate the evolutionary patterns of CO2-concentrating mechanism and chitin synthesis pathways across diatoms.
