Time-series RNA metabarcoding of the active Populus tremuloides root microbiome reveals hidden temporal dynamics and dormant core members

Jake A. Nash, Keaton Tremble, Christopher W. Schadt, Melissa A. Cregger, Corbin Bryan, Rytas J. Vilgalys

The paper uses RNA and DNA metabarcoding to study the temporal dynamics of the Populus tremuloides root microbiome, finding that active communities are more dynamic than total communities and that core members are often dormant.
