Really proud of this work led by Ruben Eichfeld! We show how a CBM domain gain/loss can rewire fungal chitinases, turning them from antifungal enzymes into immune-suppressing effectors that support plant symbiosis. www.nature.com/articles/s41...
Domain gain or loss in a fungal chitinase enables specialization towards antagonism or immune suppression - Nature Communications
Gain or loss of a particular domain contributes to functional specialization of a conserved chitinase in beneficial root endophyte towards microbial antagonism or host immune suppression.

Our new paper in New Phytologist. Establishing a setup to study plant responses to complex microbiomes. Arabidopsis thaliana grew larger and showed enhanced resistance to Botrytis cinerea on a microbiome conditioned by maize (benzoxazinoids). Defence priming uncouple the growth–defence trade-off.

Klaus Schlaeppi@kschlaeppi.bsky.social · 8mo agoPreprint: We identified soil iron levels as critical factor explaining the variation in soil microbiome feedbacks on plant growth. The soil microbiomes tend to provide more beneficial feedbacks at low levels of soil iron. Happy reading. Credits to Jan Waelchli et al.! www.biorxiv.org/content/10.6...

Science takes time - a lot of time. Time that is more and more difficult to make available because of increased workloads. Time that exceeds the temporary contracts of postdocs and PhDs. I'll illustrate this using our paper published in Nature yesterday. 🧵 (1/x) www.nature.com/articles/s41...
