🤖 RF model shows that strain ID is the most important feature, suggesting that testing strains across multiple community contexts helps reveal their competitive potential. 📊 Two major predictors also emerge: Phylogenetic and metabolic relatedness, supporting the competition–relatedness hypothesis.

🔍 Key result: 👉 Colonization success is strongly modulated by community context and cannot be predicted from single-strain performance alone, showing that microbial interactions are crucial.

🧪 We used a Synthetic Community (SynCom) approach on common bean (Phaseolus vulgaris), testing 30 bacterial communities spanning a phylogenetic diversity gradient.

🌱 New preprint with @microbialmarie.bsky.social www.biorxiv.org/content/10.6... Bacterial Strain Identity and Community Composition Drive the Seed-to-Seedling Microbiota Assembly We explore which strain traits and community features explain successful bacterial transmission from seed to seedling.⬇️
