The Mesotaenium endlicherianum SAG 12.97 genome assembly and gene models have not been determined by the JGI, but were downloaded from the Cheng et al., 2019 genome supplemental data share at figshare.com on November 21, 2019. Please note that this copy of the genome is not maintained by Cheng et al. 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.
