Research Abstract

The main objective of this study is to reveal the molecular mechanisms underlying symbiont-host relationship in deep-sea hydrothermal vent environments. We have focused on sugar chains, glycans. We have succeeded in detection, profiling, structure determination of glycans for both symbionts and their host animals. Glycans having quite unique structures were identified.
