Conserved inhibitory mechanisms of root-associated bacteria towards Arabidopsis thaliana and Chlamydomonas reinhardtii
Soil bacteria colonize plants without causing visible disease, yet many suppress host growth. The prevalence and evolutionary reach of this cryptic inhibition are unknown, because phenotyping hundreds of isolates in plants is prohibitively slow. Here we use the unicellular algae Chlamydomonas reinhardtii as a scalable...
