Chemically Mediated Microbial "Gardening" Capacity of a Seaweed Holobiont Is Dynamic.

ABSTRACT: Terrestrial plants are known to "garden" the microbiota of their rhizosphere via released metabolites (that can attract beneficial microbes and deter pathogenic microbes). Such a "gardening" capacity is also known to be dynamic in plants. Although microbial "gardening" has been recently demonstrated for seaweeds, we do not know whether this capacity is a dynamic property in any aquatic flora like in terrestrial plants. Here, we tested the dynamic microbial "gardening" capacity of seaweeds using the model invasive red seaweed Agarophyton vermiculophyllum. Following an initial extraction of surface-associated metabolites (immediately after field collection), we conducted a long-term mesocosm experiment for 5 months to test the effect of two different salinities (low = 8.5 and medium = 16.5)
