Complete chloroplast genome of the mixotrophic chrysophyte Poterioochromonas malhamensis (Ochromonadales, Synurophyceae) from Van Lake in Eastern Anatolia

We sequenced the chloroplast genome of Poterioochromonas malhamensis (Pringsheim) R.A.Andersen strain SZCZR2049, which originates from Van Lake in Turkey. This genome is 133,923 bp long, and like those currently available for six phototrophic chrysophytes, it displays a long, gene-rich inverted repeat and a very short single-copy region. Compared to its chrysophyte counterparts, the P. malhamensis inverted repeat differs noticeably in gene content and the whole genome is missing 11 protein-coding genes. The maximum likelihood phylogeny inferred from concatenated protein-coding genes positioned P. malhamensis among the chrysophytes sensu lato as sister to the clade containing the Synurales (Synurophyceae) and Chromulinales (Chrysophyceae).
