The complete mitochondrial genome of an oleaginous microalga vischeria stellata strain SAG 33.83 (Eustigmatophyceae)

Abstract

The complete mitochondrial genome of an oleaginous microalga Vischeria stellata strain SAG 33.83 was sequenced and annotated. The circular genome was 42,608 bp long with 26.7% GC content. The mitochondrial genome of V. stellata strain SAG 33.83 contained 36 protein-coding genes (PCGs), 27 transfer RNA genes (tRNAs), three ribosomal RNA genes (rRNAs). Furthermore, the phylogenetic tree was constructed to validate the evolutionary relationship based on the complete mitogenomes of V. stellata strain SAG 33.83 through combining with seven species of Eustigmatophyceae, two species of Phaeophyceae and one species of Synurophyceae algae. Phylogenetic analysis revealed that Eustigmatophyceae were more closely related to Synurophyceae than Phaeophyceae and V. stellata strain SAG 33.83 had close genetic relationship with Vischeria sp.
