  2. 1. Palaeobiology and diversification of Proterozoic-Cambrian photosynthetic eukaryotes

    Author : Heda Agić; Małgorzata Moczydłowska; Shuhai Xiao; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; microfossils; eukaryotes; Mesoproterozoic; Neoproterozoic; Cambrian; Ordovician; palaeobiology; biostratigraphy; phylogeny; China; Estonia; Siberian Platform; prasinophytes; microstructure; Raman spectroscopy; Earth Science with specialization in Historical Geology and Palaeontology; Geovetenskap med inriktning mot historisk geologi och paleontologi;

    Abstract : One of the most important events in the history of life is the evolution of the complex, eukaryotic cell. The eukaryotes are complex organisms with membrane-bound intracellular structures, and they include a variety of both single-celled and multicellular organisms: plants, animals, fungi and various protists.

  4. 2. Environmental sequencing to infer patterns of eukaryotic evolution : Combining long-read and short-read metabarcoding

    Author : Mahwash Jamy; Fabien Burki; Micah Dunthorn; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Protists; eukaryotes; environmental sequencing; ribosomal DNA; PacBio; long-read metabarcoding; phylogenetics; salt barrier; habitat evolution; eukaryotes evolution; evolutionary rate; Apicomplexa; pathogen; Biology with specialization in Systematics; Biologi med inriktning mot systematik;

    Abstract : Our view of eukaryotes is biased towards plants, animals, and fungi. But the vast majority of eukaryotic diversity is microbial in nature. These microbial eukaryotes are key players in all ecosystems on earth and are collectively known as protists. READ MORE

  5. 3. Mine the Gaps : Evolution of Eukaryotic Protein Indels and their Application for Testing Deep Phylogeny

    Author : Pravech Ajawatanawong; Sandra Baldauf; James McInerney; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; indel; insertion deletion; protein evolution; bioinformatics; non-bilateria; eukaryotes; phylogeny; Biology with specialization in Systematics; Biologi med inriktning mot systematik; Biologi med inriktning mot molekylär evolution; Biology with specialization in Molecular Evolution;

    Abstract : Insertions/deletions (indels) are potentially powerful evolutionary markers, but little is known about their evolution and few tools exist to effectively study them. To address this, I developed SeqFIRE, a tool for automated identification and extraction of indels from protein multiple sequence alignments. READ MORE

  6. 4. Protein Prenylation in Higher Eukaryotes

    Author : Ingela Parmryd; Patrick J Casey; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; biokemi; Biochemistry;

    Abstract : Protein prenylation is a post-translational process where proteins become covalently modified by an isoprenoid group. This modification adds hydrophobicity to the proteins. For all prenylated proteins identified to date, the prenyl group is an absolute requirement for their biological functions. READ MORE
