Background: Branched polymers of glucose are universally used for energy storage in cells, taking the form of glycogen in animals, fungi, Bacteria, and Archaea, and of amylopectin in plants. Some enzymes involved in glycogen and amylopectin metabolism are similarly conserved in all forms of life, but some, interestingly, are not. In this paper we focus on the phylogeny of glycogen branching and debranching enzymes, respectively involved in introducing and removing of the ?(1?6) bonds in glucose polymers, bonds that provide the unique branching structure to glucose polymers. Results: We performed a large-scale phylogenomic analysis of branching and debranching enzymes in over 400 completely sequenced genomes, including more than 200 from eukaryotes. We show that branching and debranching enzymes can be found in all kingdoms of life, including all major groups of eukaryotes, and thus were likely to have been present in the last universal common ancestor (LUCA) but have been lost in seemingly random fashion in numerous single-celled eukaryotes. We also show how animal branching and debranching enzymes evolved from their LUCA ancestors by acquiring additional domains. Furthermore, we show that enzymes commonly perceived as orthologous, such as human branching enzyme GBE1 and E. coli branching enzyme GlgB, are in fact related by a gene duplication and consequently paralogous. Conclusions: Despite being usually associated with animal liver glycogen and plant starch, energy storage in the form of branched glucose polymers is clearly an ancient process and has probably been present in the last universal common ancestor of all present life. The evolution of the enzymes enabling this form of energy storage is more complex than previously thought and illustrates the need for explicit phylogenomic analysis in the study of even seemingly ?simple? metabolic enzymes. Patterns of conservation in the evolution of the glycogen/starch branching and debranching enzymes hint at some as yet unknown mechanisms, as mutations disrupting these patterns lead to a variety of genetic diseases in humans and other mammals.

PhD scholarships at the Australian Centre for Ancient DNA, Adelaide, Australia Project 1: Epigenetic modifications in adaptation to climate change Project 2: Phylogenomic analysis of the impacts of climate change, population fragmentation and localised extinctions We have 2 PhD positions available at the Australian Centre for Ancient DNA (ACAD), School of Earth & Environmental Sciences, at the University of Adelaide. For more information about ACAD, check out http://bit.ly/1wjI463 for links to Twitter, Facebook, our blog, recent publications and the official website. The positions are open to both international and domestic students with a strong academic achievement in either of the following areas: evolutionary biology, bioinformatics, or molecular biology. Competitive scholarships are also available via the University of Adelaide Graduate Centre for domestic (http://bit.ly/1ktxIHU) and international students (http://bit.ly/1iMxKwV). Both the Australian Department of Immigration and University of Adelaide expect international applicants to meet the English Language Proficiency (ELP) requirements. The ELP is based on high scores in IELTS (International English Language Testing System) or TOEFL (Test of English as a Foreign Language). For further information please refer to http://bit.ly/1ktxIY8. The projects are described below. There is the potential for fieldwork, and training in ancient DNA, bioinformatics, genomics, and population genetics. Interested applicants are encouraged to send a resume, a cover letter, and the contact details of 3 referees to Dr Bastien Llamas (email@example.com). 1) The role of epigenetic modifications in bovid adaptation to environmental change (Australian Research Council grant LP130100646). Supervision: Dr Bastien Llamas and Prof Alan Cooper. This project will use a novel experimental system to explore the potentially important role of epigenetics in long-term evolution and how animals adapt to rapid climate change. Bones of ancient bison and cattle preserved in permafrost or caves will be analysed for epigenetic markers using advanced Next Generation Sequencing approaches, and the patterns contrasted over a 30,000-year record of major climatic and environmental shifts. It has strong potential to reveal key loci for climate adaptation in modern cattle. Most previous genetic research has been blind to epigenetic marks, and this study promises to be a major advance in addressing this issue, with considerable implications for conservation genetics and the cattle industry. 2) Using phylogenomics to record the impacts of climate change, extinction and population fragmentation (Australian Research Council grant DP140104233). Supervision: Dr Julien Soubrier and Prof Alan Cooper. We will use ancient DNA from permafrost-preserved Steppe bison bones and bovid exome capture systems to build a detailed record of the genomic impacts of rapid climate and environmental change at the end of the Pleistocene (30-11 kyr). The project will analyse how ancestral genetic diversity is distributed amongst surviving bison populations, and the role of nuclear loci under selection and drift. It will create a novel temporal dataset of genomic adaptation and evolution, and will generate critical data for studies of evolutionary processes such as extinctions, speciation and conservation biology and management. via Gmail
Global analysis of saliva as a source of bacterial genes for insights into human population structure and migration studies
Background: The genetic diversity of the human microbiome holds great potential for shedding light on the history of our ancestors. Helicobacter pylori is the most prominent example as its analysis allowed a fine-scale resolution of past migration patterns including some that could not be distinguished using human genetic markers. However studies of H. pylori require stomach biopsies, which severely limits the number of samples that can be analysed. By focussing on the house-keeping gene gdh (coding for the glucose-6-phosphate dehydrogenase), on the virulence gene gtf (coding for the glucosyltransferase) of mitis-streptococci and on the 16S-23S rRNA internal transcribed spacer (ITS) region of the Fusobacterium nucleatum/periodonticum-group we here tested the hypothesis that bacterial genes from human saliva have the potential for distinguishing human populations. Results: Analysis of 10 individuals from each of seven geographic regions, encompassing Africa, Asia and Europe, revealed that the genes gdh and ITS exhibited the highest number of polymorphic sites (59% and 79%, respectively) and most OTUs (defined at 99% identity) were unique to a given country. In contrast, the gene gtf had the lowest number of polymorphic sites (21%), and most OTUs were shared among countries. Most of the variation in the gdh and ITS genes was explained by the high clonal diversity within individuals (around 80%) followed by inter-individual variation of around 20%, leaving the geographic region as providing virtually no source of sequence variation. Conversely, for gtf the variation within individuals accounted for 32%, between individuals for 57% and among geographic regions for 11%. This geographic signature persisted upon extension of the analysis to four additional locations from the American continent. Pearson correlation analysis, pairwise Fst-cluster analysis as well as UniFrac analyses consistently supported a tree structure in which the European countries clustered tightly together and branched with American countries and South Africa, to the exclusion of Asian countries and the Congo. Conclusion: This study shows that saliva harbours protein-coding bacterial genes that are geographically structured, and which could potentially be used for addressing previously unresolved human migration events.
Background: Vertebrate mitogenomes are economically organized and usually lack intergenic sequences other than the control region. Intergenic spacers located between the tRNAThr and tRNAPro genes (?T-P spacers?) have been observed in several taxa, including gadiform species, but information about their biological roles and putative functions is still lacking. Results: Sequence characterization of the complete European hake Merluccius merluccius mitogenome identified a complex T-P spacer ranging in size from 223?532?bp. Further analyses of 32 gadiform species, representing 8 families and 28 genera, revealed the evolutionary preserved presence of T-P spacers across all taxa. Molecular complexity of the T-P spacers was found to be coherent with the phylogenetic relationships, supporting a common ancestral origin and gain of function during codfish evolution. Intraspecific variation of T-P spacer sequences was assessed in 225 Atlantic cod specimens and revealed 26 haplotypes. Pyrosequencing data representing the mito-transcriptome poly (A) fraction in Atlantic cod identified an abundant H-strand specific long noncoding RNA of about 375?nt. The T-P spacer corresponded to the 5? part of this transcript, which terminated within the control region in a tail-to-tail configuration with the L-strand specific transcript (the 7S RNA). Conclusions: The T-P spacer is inferred to be evolutionary preserved in gadiform mitogenomes due to gain of function through a long noncoding RNA. We suggest that the T-P spacer adds stability to the H-strand specific long noncoding RNA by forming stable hairpin structures and additional protein binding sites.

The implications of a Silurian and other thylacocephalan crustaceans for the functional morphology and systematic affinities of the group
Background: Thylacocephala is a group of enigmatic extinct arthropods. Here we provide a full description of the oldest unequivocal thylacocephalan, a new genus and species Thylacares brandonensis, which is present in the Silurian Waukesha fauna from Wisconsin, USA. We also present details of younger, Jurassic specimens, from the Solnhofen lithographic limestones, which are crucial to our interpretation of the systematic position of Thylacocephala. In the past, Thylacocephala has been interpreted as a crustacean ingroup and as closely related to various groups such as cirripeds, decapods or remipeds. Results: The Waukesha thylacocephalan, Thylacares brandonensis n. gen. n. sp., bears compound eyes and raptorial appendages that are relatively small compared to those of other representatives of the group. As in other thylacocephalans the large bivalved shield encloses much of the entire body. The shield lacks a marked optical notch. The eyes, which project just beyond the shield margin, appear to be stalked. Head appendages, which may represent antennulae, antennae and mandibles, appear to be present. The trunk is comprised of up to 22 segments. New details observed on thylacocephalans from the Jurassic Solnhofen lithographic limestones include antennulae and antennae of Mayrocaris bucculata, and endites on the raptorial appendages and an elongate last trunk appendage in Clausocaris lithographica. Preserved features of the internal morphology in C. lithographica include the muscles of the raptorial appendage and trunk. Conclusions: Our results indicate that some ‘typical’ thylacocephalan characters are unique to the group; these autapomorphies contribute to the difficulty of determining thylacocephalan affinities. While the new features reported here are consistent with a eucrustacean affinity, most previous hypotheses for the position of Thylacocephala within Eucrustacea (as Stomatopoda, Thecostraca or Decapoda) are shown to be unlikely. A sister group relationship to Remipedia appears compatible with the observed features of Thylacocephala but more fossil evidence is required to test this assertion. The raptorial appendages of Thylacocephala most likely projected 45 degrees abaxially instead of directly forward as previously reconstructed. The overall morphology of thylacocephalans supports a predatory mode of life.

Postdoctoral position in Systematics and Evolution A two-year postdoctoral position in Systematics and Evolution is available in the Department of Zoology, Swedish Museum of Natural History, Stockholm. Project description “Species-level phylogeny and delimitation in a biodiversity hotspot” Madagascar is well known for its high level of endemism, basically across every organism group. The combination with severe habitat degradation has “rewarded” the island with a top placement among biodiversity hotspots. The increased evolutionary research interest last twenty years has focused on vertebrates and surprisingly little is yet known about the colonization and speciation history of most insect groups. Using Hydradephagan water beetles as model organisms this project will use dated phylogenetic frameworks to analyze colonization and speciation patterns across replicated endemic radiations and clades with representatives but seemingly without radiations. Intraspecific genetic variation will be sampled to estimate parameters in the multispecies coalescent model as a window into the speciation process. The project also includes evaluation of species delimitation methods on endemic radiations with non-reciprocally monophyletic species in gene-trees. Tasks The position is part of a research project and group (Bergsten Systematic Entomology Lab: http://bit.ly/1uZz1FZ) at the Swedish Museum of Natural History on the taxonomy, faunistics, phylogeny, colonization, speciation and evolutionary history of Hydradephagan water beetles on Madagascar. The work includes DNA labwork, fieldwork, data analyses, help with supervision of student projects, article- and grant writing. The DNA labwork will be conducted at the Molecular Systematics Laboratory at the Swedish Museum of Natural History. Qualifications To be qualified for the postdoctoral position the applicant needs to have a PhD degree (or have a PhD thesis ready with a date fixed within 2014 for thesis defense) in Systematics/Phylogenetics/Evolutionary Biology or similar direction of studies. The PhD degree should have been received no more than six years before the deadline for applications. Criteria for selection Among qualified applicants selection is made according to scientific merits, quality of the PhD thesis, personal skills, the applicant´s documented knowledge in subjects of relevance for the research area, ability to master English language (both spoken and written), analytical ability, creativity, initiative, independence, teamwork and ability to cooperate. Previous experience with molecular (DNA) lab work and knowledge of relevant theory and methods (phylogenetic, dating, species delimitation, biogeographic and diversification rate analyses) weigh heavily. Experience with entomological fieldwork, taxonomic work and French language (spoken in Madagascar) are consider as additional qualifications. Terms of employment The position is for two years full time. Start of position should be in 2014 but exact date up to negotiation with the successful candidate. The position is financed by a grant from the Swedish Research Council, VR. For more information, please contact Johannes Bergsten (firstname.lastname@example.org). Union representative is Bodil Kajrup, SACO-S. Both can be reached at telephone number + 46 8 519 540 00.

Dear EvolDir Community, We are pleased to announce the RNA-seqlopedia: http://bit.ly/1z4tj30 The RNA-seqlopedia is meant as a resource for researchers trying to utilize RNA-seq protocols for their research, including de novo assembly of transcriptomes as well as quantification of gene expression. The site focuses on multiple aspects of RNA-seq work including experimental design, molecular protocols, and bioinformatic analyses. We realize that the site does not yet cover all aspects of transcriptomic analysis, and undoubtedly contains errors or dated information that will be modified. We will continue to update the site and add to its content, particularly via input from the scientific community, so we request your input! We hope that the RNA-seqlopedia will prove to be a useful research resource for those interested in transcriptomic analyses using second (and third) generation sequencing. The site was made possible by a grant from the NIH National Center for Research Resources, and is being created and maintained by the Cresko Lab at the University of Oregon. If you have any feedback or suggestions, please write us. Sincerely, Clay Small Julian Catchen Susie Bassham Bill Cresko William A. Cresko, Ph.D. Associate Professor of Biology Director, Institute of Ecology and Evolution University of Oregon http://bit.ly/1pMIFIC; @wcresko email@example.com via Gmail
*Postdoctoral position in Evolutionary Genomics and Molecular and Cellular biology * */Molecular and cellular mechanisms of hyper-resistance to stress in the ameiotic bdelloid rotifer Adineta vaga/*** ** A 3-year postdoctoral research position is available in the group of Biochemistry, Biophysics and Molecular Genetics of Micro-organisms at the life Science Institute (ISV) of the Catholic University of Louvain (UCL, Belgium) to take part in a collaborative ARC research program with the Research Units in Environmental and Evolutionary Biology (URBE) and in Cellular Biology (URBC) at the University of Namur (UNamur, Be). This postdoc position is embedded within the research project entitled: /Asexuality and ‘immortality’, bdelloid rotifers as an evolutionary ‘scandal’ and a model system in biology. /This project is funded during 5 years and will start in October 2014. *Project:* Bdelloid rotifers are micro-organisms (animals) that have recently attracted much interest in the scientific community because of their ancient asexuality and their extreme resistance to stress, such as desiccation and high doses of ionizing radiation. They are capable to survive when their genome is shattered into small fragments and repair the DNA double strands breaks (DSBs) (see Hespeels et al., 2014). Repeated cycles of chromosomal repair are thought to promote allelic recombination and gene conversion in the absence of meiosis. Moreover desiccation and the induced DNA DSBs are also thought to provide a unique opportunity to acquire horizontally transferred genes, thereby contributing to the adaptive success of these organisms. In this project, the mechanisms that make bdelloid rotifers unique in terms of evolutionary strategy and hyper-resistance to stress will be investigated based on genomic data recently obtained by our consortium for the bdelloid rotifer /Adenita vaga/ (see Flot et al, 2013, Nature 500:453-7). Genomic approaches will be used to study the dynamics of /A. vaga/ genome during cycles of desiccation/rehydration/radiationand to decipher the genetic expression program that governs the different stages of its life-style. Molecular and cellular approaches will be developed to unveil and characterize the mechanisms that allow /A. vaga/ to repair its shattered chromosomes and generate genetic diversity,as well as its dependence with respect to oxidative stress response. Finally, conditions for horizontal gene transfer and RNA interference will be investigated, opening the way to the development of reverse genetic strategies. The ultimate prospect of the project is to establish bdelloid rotifers as a new model system for the understanding of fundamental biological processes such as DNA repair, cell survival and senescence. *PIs of the consortium:* Prof. Bernard Hallet (ISV, UCL), Prof. Karine Van Doninck (URBE, UNamur), Dr. Florence Debacq-Chainiaux (URBC, UNamur)** The involved consortium brings together experts in the fields of evolutionary biology and genomics (K. Van Doninck, URBE, UNamur), DNA recombination and genome plasticity (B. Hallet, ISV, UC) and oxidative stress response (F. Debacq-Chainiaux, URBC, UNamur). The appointed candidate will be expected to share its research time on both sites under the supervision of the three PIs of the consortium. The universities are at a distance of 35km from each other and easily connected by train. *Contacts:* Prof. Bernard Hallet, Bernard.firstname.lastname@example.org Universit Catholique de Louvain. Institut des Sciences de la Vie (ISV) http://bit.ly/1qTDNQl Prof. Karine Van Doninck, email@example.com University of Namur, Laboartory of Evolutionary Genetics and Ecology (http://bit.ly/1qTDQf8) *Qualifications:* We are looking for a post-doc with a strong interest and background in evolutionary genomics and molecular and cell biology. Expertise in the field of DNA repair and recombination, chromosome structure and dynamics, and/or genomics (NGS approach) is a valuable asset. Additional experience in cell biology techniques like DNA transfection, immuno-localization, fluorescence hybridization and microscopy will be a benefit. Priority will be given to candidates with a proven track record (with several publications as a first author) who will express their motivation in developing their autonomy and their interest for new challenges. *Application://* The position is available to both foreign nationals and Belgian citizens under ‘international mobility’ status, meaning that they may not have resided in Belgium for more than 12 months over the past 3 years preceding the appointment. The duration is for 2 years (with a possible 1-year renewal) starting on the *1^st of October 2014. *The closing date for applications is *^September 5th 2014.* Interested applicants should send a cover letter (briefly describing research experience, interests, and career goal), a curriculum vitae (with list of publications), and the names of three references (With address, phone number and E mail) to Bernard HALLET (Bernard.firstname.lastname@example.org) via Gmail
