Haemophilus influenzae as a chassis for directed endosymbiosis
… biologists have begun to experimentally recreate endosymbiosis through directed endosymbiosis: the engineering of stable intracellular partnerships between distinct species. This thesis explores Haemophilus influenzae as a candidate chassis for directed endosymbiosis with Saccharomyces cerevisiae. …

Coevolution of plastid genomes and transcript processing pathways in photosynthetic alveolates
… with others, in a process termed “serial endosymbiosis”. The major non-photosynthetic alveolates are the apicomplexans, which include the malaria parasite Plasmodium. Apicomplexans are descended from free-living algae and possess a vestigial plastid, which originated through the same …

Habitat and Ecological Observations on Gymnodinium Acidotum Nygaard, a Colorless Dinoflagellate Phagocytizing Blue-Green Cryptophytes
… is discussed in the context of the Serial Endosymbiosis Theory of organelle evolution.

In between empathy and wonder lies the contamination that makes us human
… is invoked as a signifier that is both material--endosymbiosis; microbiome; the human virome--and affect, the moment that intrudes consciousness--empathy, wonder, or something in between. The role that the body and the gut plays in the performance of empathy with its constituent microbes is …

Cloning and characterization of a novel ferritin from the marine diatom Pseudo-nitzschia multiseries
… concurrently. iii Diatoms evolved from secondary endosymbiosis involving eukaryotic red algae; however, a broad phylogenetic comparison suggests that P. multiseries ferritin was likely acquired via lateral gene transfer from cyanobacteria – not from its ancestral endosymbionts. Until recently, no …

Identification of genes in Sinorhizobium meliloti relevant to symbiosis and competitiveness using signature tagged transposons
… This Gram-negative soil bacterium can enter an endosymbiosis with alfalfa plants through the formation of nitrogen-fixing nodules. S. meliloti genome sequence determination has provided a basis for different approaches of functional genomics to this bacterium. One of these approaches is gene …

Energy metabolism in Arbidopsis thaliana: TCA cycle evolution, amino acids degradation and alternative pathways
… the TCA cycle operated as isolated steps prior endosymbiosis events and that only after mitochondria acquisition it was possible for it to be organized and function as a cycle. The TCA cycle is composed by a set of eight enzymes. However, each enzyme is encoded by several genes which are …

The genome of Euglena gracilis: Annotation, function and expression
Euglena gracilis is a species of unicellular photosynthetic flagellate that inhibits aquatic ecosystems. E. gracilis belongs to the supergroup Excavata, and are an important component of the global biosphere, have biotechnological potential and is useful biological model due to their evolutionary …
