Characterization of axenic Arabidopsis thaliana

Plants and animals are naturally colonized by diverse microbiota, and althoughmechanistic studies on select host-microbe model systems have revealed important molecular underpinnings of symbiosis and pathogenesis, little is known about the dynamic relationship between a host and its associated microbiota in a community context.Here we characterize differential immune-associated phenotypes in holoxenic and axenic Arabidopsis, revealing functional attributes of plant microbiota by proxy of host phenotypic characterization.
