hela Sverige Genomics and ecology of fungal denitrifiers
Nitrous oxide (N2O) is an important greenhouse gas and the main compound destroying the ozone layer. N2O mainly originates from microbial metabolism of N compounds in soils, especially via denitrification. Most studies have focused on bacterial N2O production despite that denitrifying fungi also contribute to soil N2O emissions. The aim of the current project is to develop a general understanding of the ecology of fungal denitrifiers; an aspect we know little about in an emerging field of research. Increased knowledge of fungal denitrifiers and factors promoting fungal N2O production are essential to undertake proper actions for nitrogen management and improve the terrestrial climate regulation service.
The project adopts a functional and multi-faceted approach by using comparative genomics and comparative metagenomics, as well as experimental work with both field and lab experiments to provide novel insights into the importance of fungal denitrification for N2O production in agricultural soils. The project is organized in three main parts:
1. Fungal genomes will be explored to gain fundamental understanding of fungal denitrifiers. This will provide updated phylogenies, which will be necessary for analyzing the fungal denitrifier communities in the experimental work that follows.
2. For a first insight into the potential importance of fungal denitrifiers, global distribution patterns across the major biomes will be determined by exploring available metagenomes for fungal denitrification genes.
3. The hypotheses that soil acidification promotes fungal denitrifiers, whereas nitrogen fertilization promotes bacterial denitrifiers, will be tested using long-term field experiments combined with common garden experiments.
Data processing and analyses, and writing scientific articles constitutes extensive parts of the project.
The scientific environment:
The PhD student will work in the Soil Microbiology Group. The group performs fundamental and applied research on functional ecology of microorganisms, especially those involved in nitrogen cycling. We address questions in community ecology with relevance for climate, environment and agriculture. The group has extensive national and international collaborations.
The Department of Forest Mycology and Plant Pathology offers a stimulating research environment focusing on fundamental and applied aspects of fungal, bacterial and plant biology. Important research topics at the department include interactions between microorganisms and plants as well as ecology and evolution. Central themes are plant pathology, biodiversity and nutrient cycling in agricultural and forest ecosystems.
Kvalifikationer: We are seeking a highly motivated and team-oriented candidate interested in academic research in microbial genomics and ecology. You should have an MSc degree in microbiology, mycology or another subject relevant for the position. Formal education in either microbial ecology, ecology or molecular evolution is desired as well as previous experience with laboratory work and molecular methods. Training and documented knowledge in bioinformatics and statistics (both univariate and multivariate) are strong merits. The working language is English and excellent communication skills in English, both oral and written, are required.
The application should be written in English and include a Curriculum Vitae, a short description of experience indicating your suitability for the position and why you are interested, copies of degree certificates from higher education, a record of relevant publication where applicable, contact information of at least two references. Candidates from outside Scandinavia or countries where English is not a native language, should be able to provide evidence of proficiency in English (e.g. a TOEFL certificate or equivalent) or that English was the main language of a significant part of their education.
