PROJECT

ERATO Evolving Symbiosis Project aims at bringing about breakthroughs in our understanding of symbiosis, by making use of our novel insect-E. coli and mammal-E. coli experimental symbiotic systems, and also by applying the recent genome engineering technologies, thereby focusing on the diversity and commonality of the symbiotic mechanisms encompassing invertebrates and vertebrates.

MESSAGE

Here we are aiming at achieving an ultimate form of understanding of the evolution of symbiosis by experimentally establishing symbiotic associations between the model bacterium, E. coli, and invertebrate and vertebrate model animals, insects and mice, thereby observing, describing and analyzing the processes and mechanisms of the real-time symbiotic evolution in detail.
