Soybean (Glycine max) is one of the most economically important legumes worldwide. However, Europe strongly depends on soybean import from South American countries where soybean cultivation leads to environmental issues. To alleviate this dependency and develop socially responsible protein products, a shift towards local soybean production is imperative.

Sugar signalling

Strigolactones (SLs) are one of the best-known signaling molecules released into the rhizosphere to regulate interactions with neighboring organisms. Originally isolated from plant root exudates as germination stimulants for root parasitic plants of the Orobanchaceae family, SLs play a dual role in rhizosphere. They ensure germination of the parasitic plants in the presence of the host, leading to significant crop losses worldwide. However, their primary function lies in supporting plant growth.

Arbuscular mycorrhizal fungi (AMF) form mutualistic associations with more than 80% of all land plants. AMF provide their host plants with essential nutrients such as phosphate, in return for plant derived carbohydrates. Hence, AMF could be used in agriculture to lower the use of chemical fertilizers. However, much is still not known about this complex plant-fungal interaction. Our research focusses on the molecular mechanisms of both symbiotic partners to establish and maintain the mutualistic relationship.

Plant roots are colonized by vast amounts of microorganisms, of which many facilitate plant growth. The Goormachtig lab investigates the intricate interactions between plants and rhizosphere microbiota, with a primary emphasis on the phenotypic and molecular alterations induced by plant growth-promoting rhizobacteria (PGPR), particularly focusing on Streptomyces species and the staple crops maize and wheat.
