The Galdieria sulphuraria 002 genome sequence and gene models have not been determined by the JGI, but were downloaded from the Red Algal Resources to Promote Integrative Research in Algal Genomics webpage on October 31, 2019. Please note that this copy of the genome is not maintained by Red Algal Resources 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.

Galdieria sulphuraria 002 originates from La Solfatara volcanic crater in Italy and belongs to the Cyanidiales, a monophyletic clade of polyextremophilic unicellular red algae. The Cyanidiales thrive in acidic and thermal habitats, such as volcanoes, geysers, acid rivers, and geothermal plants. It is estimated that 1% of their gene inventory is derived from horizontal gene transfer (HGT), and the majority of these HGT-derived genes are related to polyextremophily (Rossoni et al., 2019).
