Phyla diversity in Marchantia microbiomes and a concise comparison of plant-related microbiomes. (A) M. paleacea and M. polymorpha microbiomes. Proteobacteria was the most abundant phylum for both wild M. paleacea and M. polymorpha, but Firmicutes dominated the microbiome diversity of in vitro M. polymorpha. (B) Proteobacteria was the most abundant phylum in the plant microbiomes analyzed but each microbiome had different frequencies, spanning from 30% up to 90%. Plant microbiomes were ordered according to their phylogenetic distances. Sphagnum moss¹³ served a representative for bryophytes (along with Marchantia species); Pinus represented gymnosperms¹⁴; rice¹⁶ and maize¹⁵ represented monocots; and the carnivorous plant Utricularia gibba⁶⁸ and Arabidopsis¹¹ represented dicots (see Methods).
