Meeting Summary



The microbiome is a biome assumed to support evolution of other species by stimulating conditions of the host that ensure replication of DNA for survival, fitness and reproduction. This symbiotic interaction also includes sharing metabolic pathways with the host to reduce energy consumed by both parties. Together, the host and its microbiome form a holobiont. While the main mechanisms of such holobiont interactions are largely unknown, their mode of action may in part be conserved across diverse biological systems, such as plants, corals, and humans. Such host-microbiome interactions and evolutionary selection mechanisms have not been addressed in a large interdisciplinary setting. This meeting aims to bring strong attention to holobiont mechanisms highly relevant to all biological systems and now studied in the emerging field of host-microbiome biology. In addition, the meeting will deliver new concepts to better understand the foundation of health at all levels, from organisms to ecosystems. It will explore and compare how microbiomes interact with their hosts, and how host-microbiome systems interact with their environment. This will be addressed using simple to complex biological holobionts, across a range of organisms and environments. These multi-system models reveal mechanistic similarities and evolutionary drivers of host-microbiome interactions. Comparing such systems will allow for the identification of appropriate experimental models and disclose the extent by which seemingly disparate ecological and phenotypic traits reflect similar host-microbiome interactions and mechanisms. Translation of such mechanistic knowledge will inform on the development of more effective diagnosis, prevention and treatment in a range of systems.
