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 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.

Sonia obtained her PhD in Biochemistry and Biotechnology in 2022 in the group of Prof. Anne Willems (Laboratory of Microbiology, University of Gent) and Prof. Sofie Goormachtig (VIB-UGent Center for Plant Systems Biology). During her PhD, she studied the effect of low temperatures on the microbiome of two cold tolerant plants, Valerianella locusta and Poa annua, and the model plant Arabidopsis thaliana. The aim was to identify bacteria able to alleviate cold stress in plants. She is now a postdoctoral scientist in the group of Prof. Sofie Goormachtig at VIB-UGent Center for Plant Systems Biology since 2023. As a part of the BOOSTER project, she investigates how drought shapes maize microbiomes to identify drought-enriched bacteria that might promote plant growth under this abiotic stress and understand their mode of action.
