Status
The genome sequence and gene models of Botryococcus braunii Showa strain v2.1 were downloaded from Phytozome, the Joint Genome Institute (JGI) Plant genomics portal on June 11, 2018. 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. Please note that this copy of the genome is not maintained by Phytozome and is therefore not automatically updated. The latest data is available at Phytozome.
