The Cyanidium caldarium DBV 063 E5 genome assembly and gene models have not been determined by the JGI, but were downloaded from NCBI on February 7, 2024. All published models are available as ExternalModels. In order to ensure this genome is comparable to those sequenced annotated by the JGI , we applied standard filters to ExternalModels to produce the initial GeneCatalog. A total of 100 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 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.

Cyanidium caldarium DBV 063 E5

Cyanidium caldarium is a species of the Cyanidiales that shows optimal growth at high temperatures (50 – 65°C) and low pH (0 – 4). Cells, 4-6 μm in diameter, reproduce with 4 autospores per mother cell. They are obligate photoautotrophs. Cells contain one mitochondrion and a single laminated, parietal cup-shaped chloroplast with a club-like nucleoid, while vacuoles and trienoic fatty acids are absent.
