Matchmaking in Boreal forests

In nitrogen-deficient boreal forests, atmospheric cyanobacteria play a vital role as the primary nitrogen source. Feathermosses present on these forest floors, attract and host cyanobacteria on their leaves. In this mutually beneficial relationship, cyanobacteria supply nitrogen to feathermosses in exchange for shelter, and possibly carbon. Nevertheless, the complex communication occurring during this association remains poorly understood. My research is dedicated to unraveling this communication, with a specific focus on the exchange of metabolite signals. Deciphering these signals has the potential to increase nitrogen input and promote tree growth in the forests. Additionally, it can help reduce our reliance on chemical fertilizers, which contribute to greenhouse gas emissions and climate change.
