PhD student position

Starting date: Spring 2019

A postdoctoral position studying radial plant growth is available in the group of Thomas Greb at the Centre for Organismal Studies (COS) of Heidelberg University, Germany.

Our group investigates the process of radial growth and cambium regulation as a model for elucidating developmental principles focussing on intra- and intercellular communication. In the context of an ERC project, it is envisaged that the successful applicant will address the fundamental question of how cell identities are reprogrammed during postembryonic growth processes using biochemical, molecular and/or computational methods. For more information on the project or the general setup, please view our website pages (http://www.cos.uni-heidelberg.de) or contact Thomas Greb directly.

Research at the Centre for Organismal Studies in Heidelberg is dedicated to study organismic biology from the basic molecular principles to cell biology, developmental biology and physiology both in plants and in animals at all organisational levels. The institute is fully embedded into the Life Science campus of Heidelberg University and access to state-of-the-art imaging, proteomics and genomics platforms is assured.

Successful applicants will be highly motivated, have outstanding communication skills, have published (or be close to publishing) in major international journals and be capable of working independently in a goaloriented manner. Experience in some or all of the following disciplines is desirable: plant development, genetics, histology, molecular biology, cell biology and transcriptomics. To qualify for the position applicants should have a PhD degree or equivalent obtained in a related field, preferably no longer than three years ago.

Interested candidates are encouraged to send an email including a cover letter describing their motivation, CV and contact details for two referees to Thomas Greb (thomas.greb@cos.uni-heidelberg.de). Reviewing of applications will be continued until a suitable candidate is found.

Post doc (TV-L E13, 100%)

and a

PhD student (TV-L E13, 60%)

Starting date: Autumn 2018

The project: The project addresses a fundamental and pivotal question of plant research: How are protein translation, meristem activity and autophagy regulated under nutrient deficiency to achieve optimal growth responses?

A unique feature of our research team is the combined expertise on the regulation of diverse nutrient assimilation pathways, gene expression and metabolomics profiling and the stress-induced regulation of the sensor kinase ’Target of Rapamycin’ (TOR). TOR is one of the central growth regulators in higher eukaryotes. We selected sulfur metabolism as a proxy for nutrient-deficiency based signaling, since reduced sulfur is incorporated into the amino acid cysteine. The linear and relatively simple sulfate assimilation pathway is well characterized in Arabidopsis and genetic resources are available to our research team for all steps of sulfur translocation, reduction and incorporation. The results will be used as a blueprint to understand the basic principles of TOR regulation in response to other nutrients like carbon, nitrogen and phosphorous. This will be highly relevant to engineer nutrient use efficiency in crop plants, since control of translation and stem cell activity in response to nutrient limitations is the key trigger for developmental plasticity-based stress responses.

Relevant literature: Pfeiffer et al. (2016) eLife; Dong et al. (2017) Nat. Comm.

Collaboration Partners: The project offers stimulating interactions and training opportunities within the framework of the Heidelberg Biosciences International Graduate School and all groups at COS. Strong connections to research groups in France (University of Strassbourg) and China (University of Technology and Sciences, Hefei) support the project.

Profile of candidate’s qualifications: We look for highly motivated young scientists with interest in molecular genetics and processes of cellular regulation. Practical experience in molecular biology, biochemistry or cell biology will be of benefit. The applicants should hold a M.Sc. or PhD in Biology, Biochemistry or other relevant subjects. Successful acceptance at the Heidelberg Biosciences International Graduate School is expected for the PhD student.

The University of Heidelberg is an equal opportunity employer.

Abteilung Ingrid Lohmann

The Developmental Biology Group (Prof. I. Lohmann) at the Centre for Organismal Studies (COS) in Heidelberg, Germany is looking for

POSTDOC AND/OR PHD STUDENT
to study stem cell behaviour in the Drosophila testis.

The Lohmann lab (http://ilohmann-lab.org) works on elucidating the role of HOX transcription factors in defining cell fate using Drosophila as a model. We are located at the Centre for Organismal Studies (COS) at the University of Heidelberg, Germany and part of the collaborative research network SFB873 “Maintenance and Differentiation of Stem Cells in Development and Disease” (https://www.cos.uni- heidelberg.de/index.php/sfb873?l=_e).
We now seek for enthusiastic new colleagues to analyze the interplay between germline stem cells and their support cells under homeostatic and compromised cellular conditions. In particular, the project aims at identifying pathways monitoring genome integrity in stem cells and at uncovering the role of mitotic checkpoint components in monitoring asymmetric stem cell division in the male germline. The project builds on a wide array of advanced resources established in the Lohmann lab and will provide ample opportunity to implement and apply high-end techniques to investigate stem cells of the Drosophila male stem cell system at multiple scales.
The Heidelberg Molecular Life Science Community offers a vibrant stem cell research community, as well as state-of-the-art core facilities. You will have the opportunity to closely collaborate with highly recognized stem cell researchers of the SFB873 and beyond.

Successful candidates will have experience in confocal microscopy, advanced immunohistochemistry and possibly in Drosophila genetics and molecular biology. The ability to quickly integrate into an interdisciplinary team and work independently within an academic research environment is essential. The position is immediately available, the salary is according to TV-L regulations. Disabled persons with comparable skills will be preferentially considered.

Applications should be sent to:

Abteilung Jan Lohmann

A PhD or Post-Doc position in “Cell wall signalling-mediated control of plant cell identity“, to be filled immediately, is available in the J. Lohmann and S. Wolf labs at the Centre of Organismal Studies (COS) Heidelberg.

Project Title: Cell wall signalling-mediated control of plant cell identity

Project Description:

How the development of complex multicellular organisms is accomplished through coordinated cell proliferation, differentiation, and growth is a fundamental biological question. The rigid, yet dynamic plant cell wall, is known to guide morphogenesis through selective restriction of cell expansion and is under constant surveillance by cell surface receptors connected to intracellular signalling. However, very little is known about how this cell wall-mediated feedback signalling intersects with the regulatory mechanisms of plant development. Using state-of-the-art genetic tools, life cell imaging, and scRNA-seq analysis, we aim to unravel how cues from the cell wall affect transcriptomic signatures and cellular behaviour. With thereby seek to decipher the role of cell wall signalling in the control of cell fate trajectories and to understand how extracellular cues are integrated with intracellular growth-regulatory networks in the in the shoot apical meristem, which harbours the stem cell niche generating most of the above-ground plant organs.

COS offers a vibrant research environment with a collegial atmosphere and access to a wide range of facilities. We are looking for a highly motivated individual interested in working with plants using state-of-the-art molecular biology and cell biology methods. Applicants should hold a degree in biology, biochemistry, biotechnology, or a related field. The project is carried out in association with the DFG research unit FOR2581 “Quantitative Morphodynamics of Plants”.
