Postdoc & PhD positions in Evolutionary Biology – Genome organization of AM fungi

Postdoc & PhD positions in Evolutionary Biology – Genome organization of AM fungi

At the Department of Evolutionary Biology, Uppsala University, Sweden.

Description

Arbuscular mycorrhizal (AM) fungi form symbiotic interactions with almost all terrestrial plants and have done so since plants first colonized land. The postdoc and PhD position are both part of a newly funded ERC research program aimed at understanding the ecology and evolution of these widespread and important organisms. Using state-of-the art technology, e.g., PacBio long read sequencing and single nucleus genomics methods, the research program seeks to resolve the genome organization of AM fungi so that the evolutionary consequences of their genome organization can be studied. Specifically, the project aims at testing the hypothesis that genetically distinct nuclear genotypes coexist within AM fungi. The project involves culturing of AM fungi, sorting and genotyping of nuclei from individual fungal isolates, genome and meta-genome sequencing and assembly, as well as genome size estimation. Based on the outcome of this first part, the project will be developed to connect genotype and phenotype to mycorrhizal activity.

The postdoc and PhD student will work close together and be part of an expanding research team led by Anna Rosling (http://www.ieg.uu.se/evolutionary-biology/rosling/research/) in collaboration with Hanna Johannesson (http://www.iob.uu.se/research/systematic-biology/johannesson/) at the Evolutionary Biology Centre (EBC), Uppsala University. EBC constitutes an exciting arena for multidisciplinary research in evolutionary biology in a broad sense, housing some 300 scientists and graduate students. The scientific environment with numerous seminars, journal clubs and social activities offer excellent possibilities for contacts and collaborations. Local platforms for high-performance computational analyses (https://www.uppmax.uu.se/uppnex), NGS, SNP genotyping and proteomic analyses (http://www.scilifelab.se) ensure immediate access to state-of-the-art technology. This project will utilize several of the technological platforms at SciLifeLab in Uppsala, in particular the Microbial Single Cell Genomics Platform (https://www.scilifelab.se/facilities/single-cell/).

Qualifications

Experience in bioinformatics and genome analysis is necessary and experience in mycology is a merit. The ideal candidate is scientifically motivated and can work both independently and as part of a team. High standard of spoken and written English is required.

To apply for the PhD position you must have a Master Degree in Bioinformatics, Evolutionary Biology, Microbiology, Mycology or equivalent. Attach a copy of your diploma and your master thesis with the application.

Postdoc: Uppsala University on Meiotic Drive in Fungi

POST-DOCTORAL POSITION IN THE EVOLUTION OF MEIOTIC DRIVE

A two-year postdoctoral position is available in the research group of professor Hanna Johannesson, at the Evolutionary Biology Centre (EBC), Uppsala University.

Conflicts arising from selfish genetic elements are important drivers for evolutionary change and innovation, and thus of crucial importance for genetic form and function.  The main goal of this project is to study the evolutionary dynamics of meiotic drive in fungi.  The study system is the Spore killers of Podospora anserina, a filamentous ascomycete. The ultimate aim of our research group is to combine large-scale genomic analyses with theoretical and experimental investigations to study the evolutionary dynamics of this meiotic drive system, both on a short and a long evolutionary timescale. This postdoc project will be developed after the interest of the applicant, but should preferably encompass a combination of experimental and genomic aspects. It will be a part of a collaborative effort within our research group.

Applicants should have a PhD in biology/evolutionary biology. Documented skills in molecular phylogenetics and/or population genetics, experimental and genomic work, especially using fungal model systems, is highly valued.

Start date is flexible, ideally February 1, 2016. The position may be
extended for up to two more years.

Please send your application materials by November 25 to
Hanna.Johannesson@ebc.uu.se. The application shall include: 1) a cover letter stating research interests, 2) a CV, including publication
record, 3) a short (1-2 page) description of research accomplishments, and 4) name and contact information for three references.

Please feel free to contact me at the above listed e-mail with

Postdoc: POSITION IN EUKARYOTE GENOME EVOLUTION

POST-DOCTORAL POSITION IN EUKARYOTE GENOME EVOLUTION

A two-year postdoctoral position is available in the research group of professor Hanna Johannesson, at the Evolutionary Biology Centre (EBC), Uppsala University.

State-of-the art sequencing technology has opened opportunities to comprehensively investigate structural variants (SVs: such as deletions, insertions, duplications, inversions and translocations) in genomes of natural populations. Such SVs are often associated with gene expression changes and may be of large phenotypic effects. The main goal of this postdoc project is to use sequencing data (e.g. PacBio long read sequence data) for the model system Neurospora, emerging from our most recent sequencing projects, to increase our understanding of the impact of SVs for the evolution of eukaryote genomes. In particular, we can use the well-established phylogenetic framework of Neurospora to study the accumulation of SVs over evolutionary time, and connect them to characters such as genome size expansion/retraction, mating-system transition and speciation. By combining comparative genomic, phylogenetic and population genetic analyses, the evolutionary significance of SVs in natural populations can be traced. The project will be developed after the interest of the applicant, but should encompass a perspective of genome evolution addressed by bioinformatic/genomic approaches.

Applicants should have a PhD in biology/evolutionary biology and have documented experience in bioinformatics. Documented skills in comparative genomics, molecular phylogenetics and/or population genetics is highly valued.

Start date is flexible, ideally January 1, 2016. The position can be extended for up to two more years.

Please send your application materials by September 25 to Hanna.Johannesson@ebc.uu.se. The application shall include:
1) a cover letter stating research interests,
2) a CV, including publication record,
3) a short (1-2 page) description of research accomplishments, and
4) name and contact information for three references.

Postdoc: Life strategies in the Archaeorhizomycetes soil fungi

Post doc, Life strategies in the Archaeorhizomycetes at Uppsala University

The Archaeorhizomycetes is an ancient class of ubiquitous soil fungi. Sequences representing the class have been identified from vegetated terrestrial habitats across the globe. Estimates indicate that there are hundreds of species within the class and strong patterns of habitat specificity has been documented among species. Yet the ecological role of the Archaeorhizomycetes remain unknown.

Deadline for application is March 15, 2013.
