    How infection threads pass the cell wall

    08/07/2022

    We are happy to share a new pre-print from our lab, where we demonstrate the mechanism that allows infection threads to transcellularly pass from cell to cell during rhizobial colonisation of legume roots.

    Any comments are always welcome:

    Work led by the lab of Marco Trujillo is now accepted in Plant Cell. His lab shows that the Exocyst Subunit Exo70B2 is Linked to immunity and autophagy maintaining cellular homeostasis during enhanced secretory activity. We are grateful that we could contribute a bit to this nice project.

    Congratulations to all authors!

    PhD position available

    16/01/2019

    Applications are invited for a Ph.D. position to join the Group of Marco Trujillo at the University of Freiburg.

    Research in the Trujillo lab (www.trujillolab.com) focuses on understanding ubiquitin signalling and its roles in the regulation of immune responses and general protein homeostasis. Previous and ongoing research in the Lab has uncovered key roles of ubiquitination in the regulation intracellular vesicle transport and its interplay with signalling stemming from receptor kinases.

     

    The Project

    Newly synthesized membrane proteins are delivered to the plasma membrane in a highly specific and regulated manner through the secretory pathway. In this joint project with the laboratory of Thomas Ott (University of Freiburg; https://plantcellbiology.net), the successful candidate will work on elucidating regulatory mechanisms governing the secretory activity. The project encompasses a multidisciplinary approach combining biochemistry (structural biology, protein-protein & protein-lipid interaction analyses, enzyme activity assays, mass-spectrometry), and cell biology (CLSM, TIRF/VAEM).

    This is an exciting opportunity for the applicant to join a multi-disciplinary research group within an international centre of excellence in sciences.

     

    The ideal candidate

    We are looking for a highly motivated individual with experience in protein biochemistry and cell biology. The successful candidate will possess a Master in Science (full award) in protein biochemistry or a related discipline. Can take initiative, function well in a team, and have a hands-on mentality, perseverance and critical mind-set. Proficiency in English language for both oral and written communication.

     

    Reviewing of applications will start February 1st 2019 and continue until position is filled. The position is available immediately.

    Additional Information

    The position is funded by the DFG for three years. Salary will be according to the German Public Sector Agreement (E13, 65%) commensurate to qualifications and experience.

    Please include for your application: Cover letter detailing your motivation and background for applying for the position, CV, copy of PhD degree, name and address of three referees.

    For further information and details, please contact Marco Trujillo directly marco.trujillo@bio.uni-freiburg.de .
