The University of Heidelberg offers the positions of a

PhD student (TV-L E13, 60%).

Location: Centre for Organismal Studies (COS)                          Starting date: Autumn/Winter 2019

Project: The proposed project is designed to address a fundamental question of plant research: How is co-translational imprinting of the proteome affecting proteostasis and protein translation under diverse abiotic stresses to achieve acclimative growth responses?

N-terminal protein acetylation occurs at the ribosome of eukaryotes and affects more than 80% of cytosolic proteins in humans and plants. Despite the prevalence of this imprinting mechanism on the plant proteome, we know only little about its contribution to protein function.

We recently demonstrated that N-terminal protein acetylation is dynamically regulated by the stress-hormone abscisic acid, which decreases transcription and stability of the ribosome-associated N-terminal acetyltransferase complex A (NatA). Down-regulation of NatA activity in genetically engineered plants causes sensitivity towards abiotic and biotic stresses and constitutively activates the abscisic acid response 1, 2.

This project aims to elucidate the function of N-terminal protein acetylation for stress-induced regulation of protein turnover. A unique feature of our research team is the combined expertise on profiling of stress-induced translation, co-translational modifications of proteins, and protein stability. We will apply this expertise to unravel how abscisic acid affects proteasome-dependent destruction of NatA substrates. Furthermore, we will test the importance of candidate E3 ubiquitin ligases for specific recognition of N-terminally acetylated proteins (N-degrons).

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 (CNRS/University of Paris-Saclay) and United Kingdom (University of Birmingham) support the project.

Profile of candidate’s qualifications: We look for highly motivated young scientists with interest in molecular genetics and cellular regulation. Practical experience in molecular biology, biochemistry or cell biology of plants will be of benefit. The applicants should hold a M.Sc. 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.

Profile of the host lab: The project is offered by the department of Plant Molecular Biology (www.cos.uni-heidelberg.de), which has a long-standing record to successfully graduated PhD students and a leading expertise in co-translation modification of proteins and the stress-induced regulation of translation in plants.

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:

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”.
