Post-doctoral fellow

Judith is a postdoctoral scientist in the group of Prof. Sofie Goormachtig at VIB-UGent Center for Plant Systems Biology (FWO fellowships) since 2019. She obtained her PhD in 2016 in the group of Prof. Dirk Inze, where she focused on the regulation of Arabidopsis leaf growth by sugars. After her PhD, she joined the group of Dr. Vanessa Wahl at the Department of Prof. Mark Stitt in the Max Planck Institute of Molecular Plant Physiology (Potsdam, Germany), where she studied the effect of limited nitrogen availability on flowering and tuberization in Arabidopsis and potato. In her current research, she uses this expertise to investigate plant-microbe symbiotic interactions in different plant crops. Her main focus is unraveling the role of sugar signaling during soybean and pea nodulation.

Naomi obtained her master’s degree in Biochemistry and Biotechnology from Ghent University in 2020. For her master’s thesis she performed an Erasmus exchange to the Sainsbury lab of Cambridge University (SLCU), where she worked on the role MtLSH1 and MtNOOT1/2 during early nodule organogenesis in Medicago truncatula within the group of Prof. Dr. Giles Oldroyd. Currently, Naomi is performing her PhD research (FWO-SB fellowship) at the Rhizosphere group of Prof. Dr. Sofie Goormachtig, this time shifting her focus to another symbiont: arbuscular mycorrhizal fungi (AMF). During her PhD, Naomi uses diverse single cell and -nuclei transcriptomics and proteomics approaches to obtain a better understanding of the immunity-related crosstalk occurring during the tomato-AMF symbiotic interaction.

In the context of my master dissertation, I performed research at the Rhizosphere group on the involvement of germin-like proteins (GLPs) in the establishment and progression of arbuscular mycorrhiza fungi (AMF) symbiosis. This thesis was conducted with the aim of increasing the understanding of plant genes, such as GLPs, in mediating AMF colonization, which in the long term may enhance AMF-induced crop growth benefits, and thereby its agricultural applicability as biofertilizer. In 2023, I started my PhD focussing on expanding local soybean cultivation towards northern latitudes. The establishment of symbiosis with indigenous rhizobia strains acclimatized to these regions is crucial for efficient nitrogen fixation and the production of protein-rich beans. The ‘Soy in 1000 Garden’ initiative has unveiled the coexistence of beneficial local Bradyrhizobium sp. and non-diazotrophic Tardiphaga robiniae within functional soybean nodules, raising questions about their role as either symbiotic facilitators or competitive exploiters.

Emma obtained her Master’s degree in Biochemistry-Biotechnology at Ghent University in 2022. For her Master thesis, she did an Erasmus exchange to Bremen University (Germany), where she worked on the interaction between rice and the endophyte Azoarcus olearius. After her studies, she started a PhD (FWO fellowship) in the research group of Prof. Dr. Sofie Goormachtig, under supervision of Dr. Sylwia Struk, at the VIB-UGent Center for Plant Systems Biology. Her PhD research concerns the interaction between soybean and nitrogen-fixing rhizobia, a symbiotic interaction which is called nodulation. In particular, she focuses on the regulation of nodulation and the receptor kinase NARK in this signalling pathway.

Michiel Vandecasteele obtained his PhD in Bioscience Engineering at Ghent University in 2019. During his PhD, he studied the occurrence, genotypic diversity, and the mode of action of pathogenic Alternaria species on Flemish potato fields, while also performing educational tasks as an assistant. In 2020, he returned to the Rhizosphere group as a doctor-assistant since he performed his Master's thesis in the same group eight years prior. Now, he investigates the action of drought-tolerance-inducing rhizobacteria on maize plants.

In 2021, I graduated with a Master of Science in Biology from Ghent University. My thesis, conducted at the Rhizosphere lab, focused on identifying bacteria capable of assisting lettuce in coping with cold stress. Following graduation, I joined the Lab of Microbiology under the supervision of Professor Anne Willems at Ghent University with Professor Sofie Goormachtig of the Rhizosphere lab as my co-supervisor, contributing to the 'Soja in 1000 tuinen' project. Here, I participated in a large-scale isolation campaign aimed at discovering rhizobia strains within soybean root nodules capable of nodulating soybeans at northern latitudes. Subsequently, in 2022, I obtained an FWO grant to investigate the underlying mechanisms behind variations in nodulation efficiency among different Bradyrhizobium strains, with the goal of optimizing this interaction.

I graduated in 2018 as a Master of Science in Biochemistry and Biotechnology at Ghent University, after which I performed my master thesis in the Rhizosphere group, investigating the function of parasitic KAI2 homologs in strigolactone signaling. In 2019, I then started my PhD to further unravel the KAI2 signaling pathway in Arabidopsis seeds and its role in seed germination, with a special interest in the function of the SMAX1 protein in all of this.
