Multigene Phylogeny of Choanozoa and the Origin of Animals
Multigene Phylogeny of Choanozoa and the Origin of Animals Kamran Shalchian-Tabrizi1*, Marianne A. Minge2, Mari Espelund2, Russell Orr1, Torgeir Ruden3, Kjetill S. Jakobsen2, Thomas Cavalier-Smith4 1 Microbial Evolution Research Group, Department of Biology, University of Oslo, Oslo, Norway, 2 Centre for Ecological and Evolutionary Synthesis, University of Oslo, Oslo, Norway, 3 Scientific Computer Group, Center for Information Technology Services, University of Oslo, Oslo, Norway, 4 Department of Zoology, University of Oxford, Oxford, United Kingdom Abstract Animals are evolutionarily related to fungi and to the predominantly unicellular protozoan phylum Choanozoa, together known as opisthokonts. To establish the sequence of events when animals evolved from unicellular ancestors, and understand those key evolutionary transitions, we need to establish which choanozoans are most closely related to animals and also the evolutionary position of each choanozoan group within the opisthokont phylogenetic tree. Here we focus on Ministeria vibrans, a minute bacteria-eating cell with slender radiating tentacles. Single-gene trees suggested that it is either the closest unicellular relative of animals or else sister to choanoflagellates, traditionally considered likely animal ancestors. Sequencing thousands of Ministeria protein genes now reveals about 14 with domains of key significance for animal cell biology, including several previously unknown from deeply diverging Choanozoa, e.g. domains involved in hedgehog, Notch and tyrosine kinase signaling -

Tres o quatre assignatures de micro a la carrera, i cap d'elles tractava a fons amb protistes i menys els parents unicel·lulars dels animals. En fi, "Bitxos" raros, origen dels animals... em va semblar interessant. Així que em vaig presentar al despatx del Iñaki vestit amb el tratge de comercial de Tecnocasa, per veure si podia fer les pràctiques del Màster amb ells. El primer que vaig volguer remarcar durant l'entrevista és que no pretenia anar amb tratge a la feina, que no es pensés que jo de normal vaig tan seriós... Sigui com sigui, després de rumiar-s'ho, em va dir que endavant i em va emplaçar a fer una posterior entrevista amb els diferents membres del lab perquè tries un projecte de màster. Per tant, aquí el meu primer agraïment i molt gran, al Iñaki, per permetre'm, no només fer el màster, sinó també permetre'm fer aquesta tesis al seu laboratori. També per la llibertat alhora de triar projectes i per donar-li al MCG un ambient cordial on hi dóna gust treballar. Gràcies, doncs, per deixar-me entrar al món científic per la porta de la protistologia, la genòmica i l'evolució, que de ben segur m'acompanyaran sempre. -
The Evolution of the GPCR Signaling System in Eukaryotes: Modularity, Conservation, and the Transition to Metazoan Multicellularity

Accepted: February 19, 2014 http://gbe.oxfordjournals.org/ Abstract The G-protein-coupled receptor (GPCR) signaling system is one of the main signaling pathways in eukaryotes. Here, we analyze the evolutionary history of all its components, from receptors to regulators, to gain a broad picture of its system-level evolution. Using eukaryotic genomes covering most lineages sampled to date, we find that the various components of the GPCR signaling pathway evolved independently, highlighting the modular nature of this system. Our data show that some GPCR families, G proteins, and regulators of G proteins diversified through lineage-specific diversifications and recurrent domain shuffling. Moreover, most of the at Centro de Información y Documentación CientÃfica on May 25, 2015 gene families involved in the GPCR signaling system were already present in the last common ancestor of eukaryotes. Furthermore, we show that the unicellular ancestor of Metazoa already had most of the cytoplasmic components of the GPCR signaling system, including, remarkably, all the G protein alpha subunits, which are typical of metazoans. -

On the Age of Eukaryotes: Evaluating Evidence from Fossils and Molecular Clocks
Downloaded from http://cshperspectives.cshlp.org/ on October 6, 2021 - Published by Cold Spring Harbor Laboratory Press On the Age of Eukaryotes: Evaluating Evidence from Fossils and Molecular Clocks Laura Eme, Susan C. Sharpe, Matthew W. Brown1, and Andrew J. Roger Centre for Comparative Genomics and Evolutionary Bioinformatics, Department of Biochemistry and Molecular Biology, Dalhousie University, Halifax B3H 4R2, Canada Correspondence: [email protected] Our understanding of the phylogenetic relationships among eukaryotic lineages has im- proved dramatically over the few past decades thanks to the development of sophisticated phylogenetic methods and models of evolution, in combination with the increasing avail- ability of sequence data for a variety of eukaryotic lineages. Concurrently, efforts have been made to infer the age of major evolutionary events along the tree of eukaryotes using fossil- calibrated molecular clock-based methods. Here, we review the progress and pitfalls in estimating the age of the last eukaryotic common ancestor (LECA) and major lineages. After reviewing previous attempts to date deep eukaryote divergences, we present the results of a Bayesian relaxed-molecular clock analysis of a large dataset (159 proteins, 85 taxa) using 19 fossil calibrations. We show that for major eukaryote groups estimated dates of divergence, as well as their credible intervals, are heavily influenced by the relaxed molec- ular clock models and methods used, and by the nature and treatment of fossil calibrations. Whereas the estimated age of LECA varied widely, ranging from 1007 (943–1102) Ma to 1898 (1655–2094) Ma, all analyses suggested that the eukaryotic supergroups subsequently diverged rapidly (i.e., within 300 Ma of LECA). -

Comparisons of genomes from animals and their closest relatives – 4 choanoflagellates, filastereans and ichthyosporeans – have recently revealed the genomic 5 landscape of animal origins. However, the cell and developmental biology of the first animals have 6 been less well examined. Using principles from evolutionary cell biology, we reason that the last 7 common ancestor of animals and choanoflagellates (the ‘Urchoanozoan’) used a collar complex - 8 a flagellum surrounded by a microvillar collar – to capture bacterial prey. The origin of animal 9 multicellularity likely occurred through the modification of pre-existing mechanisms for 10 extracellular matrix synthesis and regulation of cytokinesis. -
