Time-resolving the dynamics of plant autophagy
PhD position in Biology. Plant Cell and Molecular Biology.
Department of Molecular Sciences, SLU, Sweden
Project description
We are looking for a highly motivated doctoral student to join us in investigating regulation mechanisms of plant autophagy.
Autophagy is the major catabolic process of eukatyotic cells, its molecular machinery is highly conserved and is controlled by the so called autophagy-related (ATG) genes. Autophagy is implicated in developmental processes and stress responses in all eukaryotes including plants. Plant autophagy is important for drought and salt stress tolerance, plant-pathogen interactions, fecundity and longevity of the plant (1, 2). In our previous studies we demonstrated that artificial up-regulation of autophagy has an invigorating effect on plant performance (3, 4). Despite the obvious importance of plant autophagy, little is known about the dynamics of this process. In this project the doctoral student will perform a detailed time-resolved in planta analysis of autophagic response to a short and prolonged stress, focusing on duration of the transcriptional and post-translational signaling. The PhD student will use forward and reverse genetics tools, build on the systems for in vivo autophagy detection developed in our group, analyse changes in the transcriptome dynamics, use advanced fluorescent microscopy and molecular biology tools to thoroughly characterize the chain of events activating and modulating plant autophagy response to various stress conditions. The knowledge obtained in this project will be an extremely important contribution to our understanding of plant autophagy.
Furthermore, the doctoral student will have a unique opportunity to collaborate with the SweTree Technologies AB to test applicability of our proof of concept results on the crop tree species.

Education
The department is an organizing participant of two graduate schools, providing access to a broad range of advanced courses on genetics, bioinformatics, cell and molecular biology, biochemistry, advanced microscopy, structural biology, statistics, teaching in higher education, career development, writing scientific publications etc.As a part of the project, the doctorate student will receive an advanced personal training in the methods relevant for the project by the experts in our group and by our collaborators.
Work environment
Swedish Agricultural University (SLU) is one of the highly-ranked universities world-wide. The department of Molecular Sciences belongs to the NJ-faculty and is located at the Uppsala BioCenter, Ultuna campus of SLU. Our department is a vivid, multicultural workplace employing over a hundred researches with a very broad range of expertise including nanotechnology, inorganic and organic chemistry, structural biology, food science, microbiology, plant biochemistry and cell molecular biology. The department hosts or is responsible for outstanding facilities for protein crystallography, chromatography, bioreactor, NMR, mass spectrometry,advanced microscopy: AFM, SEM, confocal microscopy and contributes to the development and use of the Max IV synchrotron. The department provides a nourishing environment for establishing new transitional research. The doctoral student will be working in a young research group interested in plant autophagy.
Employment
Four years of full-time employment as a doctoral student at SLU. Additionally, the employment will be prolonged to compensate for the doctoral students' time spent on teaching at the department (up to 20% of the planned 4 years).
SLU is an Equal Opportunity Employer
