PhD student: Characterization of novel interactors of the stress hormones jasmonic and abscisic acid

Updated: 3 months ago

About the lab

The group of Specialized Metabolism (https://www.psb.ugent.be/groups/specialized-metabolism ), led by Prof. Alain Goossens at the VIB-UGent Center for Plant Systems Biology, is looking to recruit 1 PhD student. The Goossens lab focuses on the characterization of plant signaling networks that steer plant specialized metabolism within tightly regulated fitness programs, in particular those modulated by the phytohormone jasmonate.

The Department of Plant Systems Biology (PSB) belongs to the Flanders Institute for Biotechnology (VIB) and the Ghent University (UGent), both equal-opportunity employers. PSB is a world-leading plant science institute located at the heart of a renowned Plant Biotech campus in the lovely and lively city of Ghent, Belgium. Its mission is to integrate genetics, genomics and bio-computing to unravel plant biological processes and to further translate this knowledge into value for society.

Job description 

Plant phytohormones, such as jasmonate (JA), salicylic acid (SA) or abscisic acid (ABA), play crucial roles in the fitness programs that determine plant growth, development and survival in an often-hostile environment. Their perception machineries and signaling pathways have well been characterized, yet, typically our understanding of their biological relevance still reflects only part of the puzzle. That is why in our lab, we recently decided to adapt a novel technique for revealing protein-metabolite interactions, called limited proteolysis-coupled mass spectrometry (LiP-MS), for use in plants. LiP-MS offers a medium-throughput approach to map protein-metabolite interactions and thereby discover potential novel functions of bioactive metabolites. Indeed, an extensive LiP-MS screen carried out in our lab, with proteomes from different plant species and a suite of phytohormones, indicated that phytohormones may not only bind to their known canonical receptor proteins but also to a marked variety of other proteins, implicating unexpected and hitherto uncharacterized biological activities and roles. 

The PhD student will be closely involved in this project with the aim to evaluate the role of a set of potentially novel interactors of the phytohormones JA and ABA. The student will learn cutting-edge techniques in protein-metabolite interactions, proteomics, modelling, gene editing, microscopy and plant phenotyping. We expect the results of this project to reveal novel bioactivities for JA and ABA and establish new paradigm shifts in phytohormonal signaling pathways.
