Comparative Plastid Genomics of Non-Photosynthetic Chrysophytes: Genome Reduction and Compaction.

ABSTRACT: Spumella-like heterotrophic chrysophytes are important eukaryotic microorganisms that feed on bacteria in aquatic and soil environments. They are characterized by their lack of pigmentation, naked cell surface, and extremely small size. Although Spumella-like chrysophytes have lost their photosynthetic ability, they still possess a leucoplast and retain a plastid genome. We have sequenced the plastid genomes of three non-photosynthetic chrysophytes, Spumella sp. Baeckdong012018B8, Pedospumella sp. Jangsampo120217C5 and Poteriospumella lacustris Yongseonkyo072317C3, and compared them to the previously sequenced plastid genome of "Spumella" sp. NIES-1846 and photosynthetic chrysophytes. We found the plastid genomes of Spumella-like flagellates
