  Plant microbiomes are diverse communities of many microbial species. Growing evidence suggests that a complex network of interactions between members of the microbiome is necessary to maintain the health of host plants. Overall microbiome impacts can be difficult to predict and there is still much unknown about how taxonomic diversity links to function. All research on such dynamics so far has been limited to vascular plants, but the non-vascular bryophytes also have rich microbiomes and understanding these is a necessary component for understanding the evolution and ecology of plant microbiomes. This study takes advantage of the existing fungal endophyte culture collection for the model liverwort Marchantia polymorpha L. to begin expanding experiments on microbiome community interactions into bryophytes. This series of experiments reveals examples of synergy, interference, and priority effects in how fungal endophyte combinations impact M. polymorpha . These results constitute a foundation for the development of more complex synthetic community studies similar to those already existing for vascular plant models.

  Bryophytes, or non-vascular plants, provide valuable models for studying plant adaptation to land, as their physiology differs significantly from that of vascular plants. This study examines the cell wall structure of bryophytes, focusing on the tissue-specific distribution of cell wall epitopes in Sphagnum compactum (a peat moss) and Marchantia polymorpha (the model liverwort) using specific stains and immunolabeling techniques. In S. compactum, chlorocysts and hyalocysts exhibit distinct polysaccharide compositions, with methylesterified and demethylesterified homogalacturonans, arabinans, and hemicelluloses contributing to water retention, structural integrity, and photosynthetic efficiency. In contrast, M. polymorpha demonstrates a simpler yet polarized distribution of homogalacturonans, arabinans, mannans, and xyloglucans, with arabinogalactan proteins uniquely localized in rhizoids, improving their flexibility and anchorage to the substrate. Cellulose was uniformly distributed throughout all tissues in both bryophytes, while crystalline cellulose was only faintly observed. These findings highlight how cell wall adaptations contribute to ecological specialization, providing insights into the evolutionary innovations that enable bryophytes to thrive in terrestrial environments.
