🌱🦠 Excited to share part of my PhD work @mpipz.bsky.social with @hotvegetables.bsky.social as co-first, in collab with @leibnizipk.bsky.social and @ceplas.bsky.social. We found that Arabidopsis and its microbiota work together to adapt iron acquisition to soil pH. www.cell.com/cell/fulltex... 🧵
Arabidopsis uses distinct coumarins and bacterial pathways for pH-adaptive iron acquisition
Arabidopsis coordinates Fe acquisition with its root microbiota by releasing distinct coumarin chemotypes in response to environmental pH. These root-exuded specialized metabolites interact with root-...
