| 研究開始時の研究の概要 |
This study will provide fundamental insights into the functioning of eukaryote-eukaryote photosymbioses through the study of large benthic foraminiferal host-symbionts associations, photosymbiosis functionning and their effect of the hosts's ecological traits.
|
| 研究実績の概要 |
Metagenomes were obtained from a total of 50 single-cell foraminifera specimens belonging to 10 different species. Analysis of the results are in progress and show diverse symbioses with foraminifera harbouring green and red algae, diatoms and dinoflagellates. Preliminary results suggest that symbionts are host specific.
Behavioural experiments using timelapse imaging were done to observe changes in behaviour with light conditions.
Experimental images remain to be analyzed before drawing any quantitative conclusions about the foraminiferal behavioural response but qualitative observations suggest that the behaviour of the foraminifera might be influenced by their symbionts.

| 今後の研究の推進方策 |
This fiscal year I will focus on the analysis of the foraminiferal metagenomes and prepare the associated publication.
At the same time, behavioural analyses will be performed and complementary metabolic activity measurements will be done.
