| Outline of Final Research Achievements |
The aim of this research is to verify, “Every gene is everywhere, but the environment selects” hypotheses by conducting meta-omics approach in different spatial marine environments. The seawater samples for meta-omics analyses obtained from surface, mesopelagic and bathypelagic of each subarctic and subtropical zone in the western North Pacific Ocean.
Many microorganisms belonging to different taxonomical position may share the functionally similar genes. Also, genes coding for basic cellular metabolic functions are scattered among various microorganisms in the wide range of environments. Therefore, shift of the community structures is not necessarily accompanied with genetic structures. Under certain environment, genes to be expressed for particular functions are selected and the expression gives advantages to the cells harbouring the gene. Further meta-genomic analyses together with multi-omics approaches may verify this hypothesis in different temporal marine environments.
