  2. 1. Mitochondrial and Eukaryotic Origins : A Phylogenetic Perspective

    Author : Björn Brindefalk; Siv Andersson; James McInerney; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Molecular evolution; Phylogenetics; Mitochondrial origin and Evolution; Molecular biology; Molekylärbiologi; molekylärbiologi; Molecular Biology;

    Abstract : Mitochondria are eukaryotic cellular organelles responsible for power-generation, believed to have come into existence by an endo-symbiontic event where a bacterial cell was incorporated by an un-specified "proto-eukaryote". Phylogenetic analysis have shown that the mitochondrial ancestor was most related to present-day alpha-proteobacteria, although the exact nature of the mitochondrial progenitor remains disputed.

  4. 2. Exploration of microbial diversity and evolution through cultivation independent phylogenomics

    Author : Joran Martijn; Thijs J.G. Ettema; Andrew Roger; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; cultivation independent genomics; metagenomics; single-cell genomics; metagenomic binning; phylogenetics; phylogenomics; phylogenetic artefacts; comparative genomics; gene tree-species tree reconciliation; rRNA amplicon sequencing; Tara Oceans; origin of mitochondria; Alphaproteobacteria; Rickettsiales; Haloarchaea; endosymbiosis; Biologi med inriktning mot molekylär evolution; Biology with specialization in Molecular Evolution;

    Abstract : 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. READ MORE

  5. 3. Genomic and evolutionary exploration of Asgard archaea

    Author : Eva F. Caceres; Thijs J. G. Ettema; Simonetta Gribaldo; Uppsala universitet; []
    Keywords : archaea; Asgard; eukaryogenesis; metagenomics; genome binning; phylogenetics; phylogenomics; comparative genomics; gene tree-species tree reconciliation; ancestral reconstruction; long-read metagenomics;

    Abstract : 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. READ MORE

  6. 4. Mitochondrial Genome Analysis Using Next Generation Sequencing for Forensic Applications

    Author : Kimberly Sturk-Andreaggi; Marie Allen; Antti Sajantila; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Mitochondrial DNA; next generation sequencing; massively parallel sequencing; forensic genetics; nuclear mitochondrial DNA segment NUMT ; length heteroplasmy; haplogroup; quality control; population data; Biology with specialization in Molecular Biology; Biologi med inriktning mot molekylärbiologi;

    Abstract : Mitochondrial DNA (mtDNA) analysis plays a specialized role in forensic applications, overcoming certain limitations of autosomal DNA markers. The high copy number and uniparental inheritance pattern of mtDNA are advantageous in cases involving shed hairs and aged skeletal elements, especially decades-old missing persons cases. READ MORE
