1. Exploring the diversity and evolution of giant viruses in deep sea sediments using genome-resolved metagenomics
Sammanfattning : Viruses are the most abundant biological entities on this planet, which is impressive considering that they are completely dependent on their hosts for reproduction. Recently the idea of what viruses are has changed dramatically, with the discovery of giant viruses that belong to the Nucleocytoplasmic Large DNA Viruses (NCLDV), such as Mimiviridae, Marseilleviridae, and the proposed families Pandoraviruses, and Pithoviruses.

2. Genomic and evolutionary exploration of Asgard archaea
Sammanfattning : Current evolutionary theories postulate that eukaryotes emerged from the symbiosis of an archaeal host with, at least, one bacterial symbiont. However, our limited grasp of microbial diversity hampers insights into the features of the prokaryotic ancestors of eukaryotes. LÄS MER
3. Expanding the Chlamydiae tree : Insights into genome diversity and evolution
Sammanfattning : Chlamydiae is a phylum of obligate intracellular bacteria. They have a conserved lifecycle and infect eukaryotic hosts, ranging from animals to amoeba. Chlamydiae includes pathogens, and is well-studied from a medical perspective. LÄS MER
4. Exploration of microbial diversity and evolution through cultivation independent phylogenomics
Sammanfattning : Our understanding of microbial evolution is largely dependent on available genomic data of diverse organisms. Yet, genome-sequencing efforts have mostly ignored the diverse uncultivable majority in favor of cultivable and sociologically relevant organisms. LÄS MER
5. Novel insights into protist diversity and niche adaptation using single cell transcriptomics
Sammanfattning : Protists are a polyphyletic group of microbes that represents the vast majority of eukaryotic diversity. Despite this, most sequencing efforts targeting eukaryotes have been focused on animals, fungi and plants. LÄS MER
