Galdieria sulphuraria Assembly and Gene Annotation

About Galdieria sulphuraria

Galdieria sulphuraria is an extremophilic unicellular species of red algae. It is the type species of the genus Galdieria. It is known for its broad metabolic capacities, including photosynthesis and heterotrophic growth on over 50 different extracellular carbon sources. The members of the Cyanidiophyceae family are among the most acidophilic known photosynthetic organisms, and the growth conditions of G. sulphuraria, pH between 0 and 4, and temperatures up to 56°C, are among the most extreme known for eukaryotes. Analysis of its genome suggests that its thermoacidophilic adaptations derive from horizontal gene transfer from archaea and bacteria, another rarity among eukaryotes.

Assembly

The assembly presented is the ASM34128v1 assembly submitted to INSDC with the assembly accession GCA_000341285.1.

Annotation

The annotation presented is derived from annotation submitted to INSDC with the assembly accession GCA_000341285.1, with additional non-coding genes derived from Rfam. For more details, please visit INSDC annotation import.

Repeats were annotated with the Ensembl Genomes repeat feature pipeline. There are: 9,272 Low complexity (Dust) features, covering 0 Mb (3.6% of the genome); 251 RepeatMasker features (annotated with the RepBase library), covering 0 Mb (0.3% of the genome); 1,654 RepeatMasker features (annotated with the PGSB-REdat library), covering 0 Mb (1.5% of the genome); 1,406 Tandem repeats (TRF) features, covering 0 Mb (1.0% of the genome).
