| Outline of Annual Research Achievements |
- We showed using molecular, morphological and reproductive analysis that the Okinawa Oikopleura dioica is probably a different species or sub-species to Osaka specimen (Masunaga et al, 2022).
- We have recently completed the detailed genome comparisons between the Okinawa and Osaka Oikopleura dioica species (Plessy et al, Submitted).
- We have established comparative assays to measure the development rate of Oikopleura dioica in different saline concentrations.
- We have performed RNA-seq experiments of different time-points of exposure to different saline conditions.

| Current Status of Research Progress |
Current Status of Research Progress
3: Progress in research has been slightly delayed.
Reason
- We are currently analysing the RNA-seq data.
- We are preparing to test further conditions (temperature, acidity).
- Maintaining constant temperatures over long periods is currently a technical challenge.
|
| Strategy for Future Research Activity |
- We are detecting clear phenotypic changes depending on the conditions.
- Our main focus is to understand the gene regulation underlying the adaptation of behaviours.
- Given the large number of cell types in an organism, we are currently testing single-cell RNA seq and cell line development.
