    Species of the eukaryotic phylum Rhodelphidia are non-photosynthetic, flagellate predators with gene-rich genomes, in contrast to their closely related sister lineage—the red algae—which are immotile, typically photoautotrophic and have relatively small intron-poor genomes and reduced metabolism.

    Successive fusion of yeast chromosomes is used to produce a single-chromosome strain that is viable, albeit with slightly reduced fitness.

    Eukaryotes acquired their prokaryotic genes in two episodes of evolutionary influx corresponding to the origin of mitochondria and plastids, respectively, followed by extensive differential gene loss, uncovering a massive imprint of endosymbiosis in the nuclear genomes of complex cells.

    To investigate the core engine of the eukaryotic mitotic cycle, a minimal control network has been generated in fission yeast that efficiently sustains cellular reproduction. Orderly progression through the major events of the cell cycle is driven by oscillation of an engineered minimal CDK module lacking much of the canonical regulation.
