The answer is that now we do. This winter Anne and Elinor have been in discussions with Formidlingsavdelingen and they have drawn up landscape and portrait templates for us. Portrait (sample columns) – portrait blank – landscape (sample columns) – landscape blank. Use of the templates are optional and the text included is meant as an example only. However, everyone MUST include the SFF logo and the UiB logo on all posters. Follow this link to the UiB intranet and the profiltorg in the left sidebar to learn more about ordering visit cards. Finding out who does what … Journalists are generally satisfied with the information that they get from UiB, but … In early March På Høyden published the results of a study by Aaland Research Centre that considered how journalists evaluated UiB’s dissemination of information in 2009. UiB scored generally between 6 & 7 on a scale between 1 & 10. The study also gave journalists the possibility of giving suggestions on how to be better. Two suggestions stood out: good personal pages – that these should particularly include information about one’s research interests and competencies. competency lists – that it should be easy to find out who does what in each unity (example) Elinor has begun work on a CGB competency list (the example list seemed a bit long, so this is something shorter). Please check that the lists giving the names of group members for each of the six themes are up to date – they come from the old web site and there have been changes! Feedback welcome!

Environ Microbiol 12:1075-1088 Abstract: Summary Ammonia-oxidizing archaea are frequent and ubiquitous inhabitants of terrestrial and marine environments. As they have only recently been detected, most aspects of their metabolism are yet unknown. Here we report on the occurrence of genes encoding potential homologues of copper-dependent nitrite reductases (NirK) in ammonia-oxidizing archaea of soils and other environments using metagenomic approaches and PCR amplification. Two pairs of highly overlapping 40 kb genome fragments, each containing nirK genes of archaea, were isolated from a metagenomic soil library. Between 68% and 85% of the open reading frames on these genome fragments had homologues in the genomes of the marine archaeal ammonia oxidizers Nitrosopumilus maritimus and Cenarchaeum symbiosum. Extensions of NirK homologues with C-terminal fused amicyanin domains were deduced from two of the four fosmids indicating structural variation of these multicopper proteins in archaea. Phylogenetic analyses including all major groups of currently known NirK homologues revealed that the deduced protein sequences of marine and soil archaea were separated into two highly divergent lineages that did not contain bacterial homologues. In contrast, another separated lineage contained potential multicopper oxidases of both domains, archaea and bacteria. More nirK gene variants directly amplified by PCR from several environments indicated further diversity of the gene and a widespread occurrence in archaea. Transcription of the potential archaeal nirK in soil was demonstrated at different water contents, but no significant increase in transcript copy number was observed with increased denitrifying activity. Cardenas P, Rapp HT, Schander C, Tendal OS Molecular taxonomy and phylogeny of the Geodiidae (Porifera, Demospongiae, Astrophorida) – combining phylogenetic and Linnaean classification. Zoologica Scripta 39:89-106 Abstract: Cardenas, P., Rapp, H.T., Schander, C. & Tendal, O. S. (2010). Molecular taxonomy and phylogeny of the Geodiidae (Porifera, Demospongiae, Astrophorida) - combining phylogenetic and Linnaean classification.-Zoologica Scripta, 39, 89-106. According to the fossil records, the Geodiidae represents one of the oldest families of demosponges (Phylum Porifera). There are approximately 220 described extant species, geographically and bathymetrically widely distributed around the world. Species of this family all share a two-layered cortex with ball-shaped spicules called 'sterrasters' in the endocortex. However, molecular studies have questioned the monophyly of the group. Moreover, the evolutionary history and the intrafamily relationships of the Geodiidae are not fully resolved. Using a partial sequence of the cytochrome c oxidase subunit 1 (COI) gene and a partial sequence of the 28S rDNA gene (D1-D2 domains), we present the first molecular phylogeny focusing oil this group. The congruent results from the two gene fragments suggest that (i) the Geodiidae is monophyletic, (ii) the Erylinae/Geodinae subdivision sensu Sollas, 1888 is valid and that (iii) Isops and Sidonops ire junior synonyms of Geodia. The synonymization of Isops and Sidonops implies that the oscule/pore morphology as a diagnostic character should be abandoned. Geodia bentscheli nom. nov. has been given for Geodia mesotriaena (Hentschel, 1929). This study served as the basis for a revised phylogenetic classification of the Geodiidae. Well-supported clades led to the establishment of clade names following the PhyloCode. The Geodinae clade is strongly supported and notably composed of Depressiogeodia, Cydonium and Geodia. A morphological synapomorphy of Geodinae is the presence of euasters in the ectocortex. The Erylinae (Erylus, Penares, Caminus and Pachymatisma) form a strongly supported monophyletic group with three morphological

  • Archaea and the Origin of Eukaryotes
    REVIEWS Archaea and the origin of eukaryotes Laura Eme, Anja Spang, Jonathan Lombard, Courtney W. Stairs and Thijs J. G. Ettema Abstract | Woese and Fox’s 1977 paper on the discovery of the Archaea triggered a revolution in the field of evolutionary biology by showing that life was divided into not only prokaryotes and eukaryotes. Rather, they revealed that prokaryotes comprise two distinct types of organisms, the Bacteria and the Archaea. In subsequent years, molecular phylogenetic analyses indicated that eukaryotes and the Archaea represent sister groups in the tree of life. During the genomic era, it became evident that eukaryotic cells possess a mixture of archaeal and bacterial features in addition to eukaryotic-specific features. Although it has been generally accepted for some time that mitochondria descend from endosymbiotic alphaproteobacteria, the precise evolutionary relationship between eukaryotes and archaea has continued to be a subject of debate. In this Review, we outline a brief history of the changing shape of the tree of life and examine how the recent discovery of a myriad of diverse archaeal lineages has changed our understanding of the evolutionary relationships between the three domains of life and the origin of eukaryotes. Furthermore, we revisit central questions regarding the process of eukaryogenesis and discuss what can currently be inferred about the evolutionary transition from the first to the last eukaryotic common ancestor. Sister groups Two descendants that split The pioneering work by Carl Woese and colleagues In this Review, we discuss how culture- independent from the same node; the revealed that all cellular life could be divided into three genomics has transformed our understanding of descendants are each other’s major evolutionary lines (also called domains): the archaeal diversity and how this has influenced our closest relative.

Using culture-independent techniques, we now show that Archaea are also abun- dant and widespread on corals. Sequence analyses of Archaea on 3 species of Caribbean corals revealed that coral-associated Archaea are novel, diverse, and include representatives from both the Crenarchaeota and Euryarchaeota. Unlike zooxanthellae and Bacteria, the Archaea do not appear to form species-specific associations with reef-building corals. Fluorescent in situ hybridizations with peptide nucleic acid (PNA) probes showed that Archaea were present at >107 cells cm–2 on Porites astreoides, comprising nearly half of the prokaryotic community. This study and one by Kellogg (Mar Ecol Prog Ser 273:81–88) show that Archaea are abundant, diverse, and potentially important com- ponents of the coral holobiont.

Accepted: February 16, 2019 Abstract The last two steps of the purine biosynthetic pathway may be catalyzed by different enzymes in prokaryotes. The genes that encode these enzymes include homologs of purH, purP, purO and those encoding the AICARFT and IMPCH domains of PurH, here named purV and purJ, respectively. In Bacteria, these reactions are mainly catalyzed by the domains AICARFT and IMPCH of PurH. In Archaea, these reactions may be carried out by PurH and also by PurP and PurO, both considered signatures of this domain and analogous to the AICARFT and IMPCH domains of PurH, respectively. These genes were searched for in 1,403 completely sequenced prokaryotic genomes publicly available. Our analyses revealed taxonomic patterns for the distribution of these genes and anticorrelations in their occurrence. The analyses of bacterial genomes revealed the existence of genes coding for PurV, PurJ, and PurO, which may no longer be considered signatures of the domain Archaea. Although highly divergent, the PurOs of Archaea and Bacteria show a high level of conservation in the amino acids of the active sites of the protein, allowing us to infer that these enzymes are analogs.

    Systema Naturae. The classification of living organisms. c Alexey B. Shipunov v. 5.601 (June 26, 2007) Preface Most of researches agree that kingdom-level classification of living things needs the special rules and principles. Two approaches are possible: (a) tree- based, Hennigian approach will look for main dichotomies inside so-called “Tree of Life”; and (b) space-based, Linnaean approach will look for the key differences inside “Natural System” multidimensional “cloud”. Despite of clear advantages of tree-like approach (easy to develop rules and algorithms; trees are self-explaining), in many cases the space-based approach is still prefer- able, because it let us to summarize any kinds of taxonomically related da- ta and to compare different classifications quite easily.

Here, we report isolation of the first cultivated representative from the THSCG, named as NAS-02. Physiological characterization demonstrated that the isolate was a thermoacidophilic, sulfur- and iron-reducing organoheterotroph, which was supported by gene contents encoded in its complete genome. There was no evidence for ammonia oxidation by the isolate. Members in THSCG are likely thermophiles, and may play roles in 1234567890();,: 1234567890();,: degrading cell debris as a scavenger and in biogeochemical cycling of sulfur and iron in the hot environments, as suggested by the physiological characteristics of the isolate and the geographical distribution of the 16S rRNA gene sequences of THSCG in terrestrial hot springs and marine hydrothermal fields. Phylogenetic analysis suggests that the THSCG lineage represented by NAS-02 has gained the ability of sulfur reduction via horizontal gene transfer. Based on the phylogeny and physiology, we propose the name Conexivisphaera calidus gen.
