| contents | Genomes of nitrogen-fixing eukaryotes reveal an alternate path for organellogenesis. Frail, Sarah Steele-Ogus, Melissa Doenier, Jon Moulin, Solène L Y Braukmann, Tom Xu, Shouling Yeh, Ellen Biological Evolution Diatoms Genome, Plastid Multigene Family Nitrogen Fixation Organelle Biogenesis Origin of Life Proteome Symbiosis Transformation, Genetic Cyanobacteria Gene Transfer, Horizontal Endosymbiotic gene transfer (EGT) and import of host-encoded proteins have been considered hallmarks of organelles necessary for stable integration of two cells. However, newer endosymbiotic models have challenged the origin and timing of such genetic integration during organellogenesis. diatoms contain diazoplasts, obligate endosymbionts derived from cyanobacteria that are closely phylogenetically related to UCYN-A, a recently described nitrogen-fixing organelle. Diazoplasts function as permanent membrane compartments in hosts, but it is unknown if genetic integration has occurred. We report genomic analyses of two diatom species, freshwater and marine , which are highly divergent but share a common ancestor at the origin of the endosymbiosis |
