Stability and host specificity in the seaweed microbiome

Mar­ine mac­roal­gae are found­a­tion spe­cies that are col­on­ized by di­verse and vari­able mi­cro­bial com­munit­ies. Mi­crobes in­flu­ence mac­roalgal health and eco­sys­tem func­tion­ing. Ma­nip­u­lat­ing the mac­roalgal mi­cro­bi­ome may en­hance the kelp cul­tiv­a­tion for in­dus­trial and res­tor­a­tion pur­poses by mod­u­lat­ing growth or en­han­cing re­si­li­ence to en­vir­on­mental stressors. Yet, it is un­clear how to ef­fi­ciently design and im­ple­ment strategies for mi­cro­bi­ome ma­nip­u­la­tion. One ap­proach is to fo­cus on the core mi­crobes (those that are con­sist­ently as­so­ci­ated with a mac­roalgal host) as key tar­gets be­cause they are hy­po­thes­ized to be more likely to in­flu­ence host bio­logy. However, the high vari­ab­il­ity and func­tional re­dund­ancy ob­served in the mac­roalgal mi­cro­bi­ome mean that it is not clear how to define the core or whether such a concept is use­ful in this sys­tem. I will dis­cuss work as­sess­ing the sta­bil­ity of the mac­roalgal mi­cro­bi­ome over time at the in­di­vidual and pop­u­la­tion level and show that al­though no bac­teria are al­ways present on our fo­cal mac­roal­gae, many are con­sist­ently as­so­ci­ated across time and space.
