Major Microbial Transitions: From the origin of life to the origin of the domains

[コンビーナ/ Convenor]
Shawn E. McGlynn (Tokyo Inst. Technol.), Takuro Nunoura (JAMSTEC), Masaru Nobu (AIST)

What is the history of metabolic innovation in relationship to the tree of life? How were major biological transitions facilitated by these biochemical innovations? In this session, we invite presenters who can help address these questions through a variety of techniques including: culturing, field work, theory, and bioinformatics. In addition to welcoming those who have new data to share, we also invite participants who can share new hypotheses that might be tested by others as well as those who can supplement microbial inferences using orthogonal data (e.g. geochemical studies).
We ask presenters to share their newest data - including their unpublished results - and we also ask the audience to come prepared to participate. To facilitate vigorous interactions, our session will begin with an overview of open questions given by the session organizers. Next we will hear from invited experts. At the end of the session, participants will hear a summary talk which aims to give further insight and also criticism to the former talks. Audience members are asked to participate at all the stages.

The Impact of Interactions

[コンビーナ/ Convenor]
Yoshitomo Kikuchi (AIST), Hideomi Itoh (AIST)

The world is full of diverse organisms, and their complex interactions have impacted biodiversity and organismal evolution. However, we understand only a small fraction of the important interactions among organisms. In this symposium, we will introduce recent progress on interactions between microbes and eukaryotic organisms, as well as the diversity and functions of these interactions, to illustrate how organismal interactions have impacted evolution. This symposium hosts four international speakers, and will cover a wide range of interactions between animals, plants, fungi, protists, archaea and bacteria, from their molecular bases to their ecological impacts.
The first speaker, Dr. Haoyang Shen (Univ. Tokyo), focuses on interactions between fungi and mycophagous mites in agricultural fields. Surprisingly, mycophagous mites feed on N2O-producing fungi, reducing N2O emissions from agricultural soils. Second, Dr. Yuya Sato (AIST) will discuss a recently discovered host-symbiont reciprocal insecticide detoxification relay, by which insect hosts obtain microbially conferred insecticide resistance. The third speaker, Dr. Filip Husnik (OIST), will present a current knowledge about bacterial and archaeal symbioses in protists. The fourth speaker, Dr. Peter Mergaert (CNRS), will present how a classic yet novel model system, legume-Rhizobium symbiosis, can be stabilized by antimicrobial peptides.
New concepts presented by these four front-runners will open new avenues of organismal interaction studies.

  1. Haoyang Shen (The University of Tokyo) Invited speaker
    Defending against fungal threats from agricultural soils via intensified belowground fungal grazing
  2. Yuya Sato (AIST, EMRI)
    Insecticide detoxification through mutual cooperation between host and symbiont
  3. Filip Husnik (OIST) Invited speaker
    Bacterial and archaeal symbioses with protists: Similarities and differences with animal symbioses
  4. Peter Mergaert (I2BC, Univ. Paris-Saclay, CEA, CNRS) Invited speaker
    The BacA and YejABEF peptide uptake transporters of Sinorhizobium meliloti mediate interspecies interactions between bacteria and between bacteria and plants

Multidisciplinary English session:Microbial ecology, Fundamentals and Applications

[コンビーナ/ Convenor]
Hiroyuki Kashima (JAMSTEC), Yukihiro Kinjo (OIST)
JSME Committee for the Promotion of Diversity and Career Development

JSME Committee for the Promotion of Diversity and Career Development is pleased to have the second Multidisciplinary English session at 34th JSME annual meeting. This session aims to encourage scientific discussion in English in JSME meetings, and to provide a new forum for a diverse community associated with microbial ecology, including those who did not participate in the JSME activities (especially non Japanese-speaking people). We will invite several keynote speakers and accept a wide range of oral presentations from students and young scientists. The excellent presentation will be awarded by the Committee.
Microbes that are ubiquitous in natural environments and in artificial systems have shaped the biosphere on the Earth, and their activities also play significant roles in grand challenges such as human health, food production, waste management, energy and environmental conservation, and climate change. We seek session contributions across all aspects of microbial ecology which covers such a diverse microbial life with a range of spatial and temporal scopes. By discussing wide research topics, we would like to exchange ideas about fundamental understanding of microbes and their applications. We would like to have fun with exciting discussions as well as to have opportunity to foster communication with people all over the microbial ecology community.
