Important Announcement: International Conference on Holobionts

Over the last few years, the terms holobiont and hologenome have received heightened attention, leading to a high-water mark of the 1st dedicated conference on the topic next year at the Paris Natural History Museum (see below). The meeting will be an important event for the community in order to set goals and achieve unity, understanding, and needs for the future. I think it will also be an opportunity to resolve misuses of the terms and associated concepts (Getting the Hologenome Concept Right, mSystems). Many factors have played a part in raising the profile of these terms and concepts including our work and others. Due to an existing heavy travel schedule, work-life balance, and teaching, I declined the invitation to speak at this conference and recommended several young scientists. I heartily endorse this conference and encourage keeping a close eye on developments that come from it. While it is the 1st conference dedicated to the topic, many other conference symposiums and workshops on the topic are brewing or have already taken place. There will hopefully be a 2nd International Conference on Holobionts in the future. 

International Conference on Holobionts,
Paris (Natural History National Museum), April 19-21, 2017

It is becoming increasingly clear that the development, nutrition, physiology and health of most organisms are influenced by the complex microbial communities they host, hereby shaping their ecology and evolution. Biology is indeed undergoing a paradigm shift, where individual phenotypes are seen as a result of the combined expression of the host and associated microbe genomes, leading to the popularization of the holobiont concept (the host and its microbiota) and the hologenome (the collective genomes of a holobiont). Ecological and technical advances, especially in next generation sequencing technologies, have greatly contributed to this conceptual shift, thereby revealing the diversity and roles of the microbes hosted by diverse organisms, from people and plants, to sponges and insects. The scientific community has now recognized that the host organisms cannot be studied without taking resident microbiomes into account, making holobiont research imperative across numerous fields of the life and medical sciences.

The objective of the International Conference on Holobionts, Paris 2017 is to, for the first time, bring scientists together who are interested in holobiont systems and their study. This conference will highlight major advances in defining the key roles of host-borne microbiota in the ecology and evolution of higher organisms and the potential implications for human health, food production and ecosystem functioning. In addition, the conference will offer a platform for debate related to the definition, assembly and evolution of holobionts. By bringing a range of holobiont researchers together, the International Conference on Holobionts seeks to help consolidate the field, facilitate exchange of knowledge across systems and approaches and stimulate further developments in this emerging discipline.

Scientific program
This conference will address the following topics:
  1. Holobionts and evolution
  2. Emerging approaches to holobiont research
  3. Microbiota and host health
  4. Mechanisms for holobiont assembly
  5. Metabolic interactions between host and microbiota
For each topic, we encourage oral and poster communications on holobiont systems from different perspectives including theoretical, empirical, fundamental and applied researches.

Practical aspects
This conference will last 2.5 days, from April 19th 2 p.m. to from April 21st 4 p.m. It will take place right in the center of Paris, in the heart of “Quartier Latin” in the prestigious Grand Amphithéâtre of the Natural History National Museum ( Note that for space constraints, we won’t be able to take more than 300 registrations. Registrations will open by November 15, 2016 and be closed by January 30, 2017. A dedicated website for registration and practical information is under construction at
