Purpose of This Mini-symposium
A new Japanese-French research cooperation sponsored by the Japan Science and TechnologyAgency (JST), “Morpho-molecular diversity assessment of ecologically, evolutionary, andgeologically relevant marine plankton (Radiolaria)” under the research field “Biodiversity
Monitoring in Marine Ecosystems” of the program “Structure and Function of Biomolecules” as
the Strategic Japanese-French Cooperative Program has started from September, JFY2011, witha co-leaders, Drs. SUZUKI, Noritoshi (Tohoku University, Japan) and NOT, Fabrice (CNRS). In
this program, two scientific goals (1) to establish unambiguous connections between morphologicaland molecular diversity of Radiolaria and their symbionts and (2) to explore the function of theseorganisms in marine ecosystems in ecological and paleoecological context are objected with highquality, taxonomically validated reference data to assess organismal (genetic barcode markers)
and functional (transcript) diversity. On the other hand, an independent program to examineradiolarians and planktons off Sesoko-Jima, Okinawa, Japan is annually conducted as “theObservation Tour of Living Radiolarians and Planktons at Sesoko Island” presided over by Prof.
MATSUOKA, Atsushi, as a project leader of the Institute of Science on Form, Niigata University.”
The French and Japanese members in the JST program are participating to the Sesoko Tour toefficiently collect plankton samples, and this is a good opportunity to discuss and exchange atremendous knowledge of molecular biology, morphology, evolution and geology between Japanand French between two independent programs. In this mini-symposium, speakers will present
the state-of-art researches, discuss how to exchange these advanced techniques and knowledge so
as to lead the future direction of biological and paleontological radiolarian studies between Japanand France.
平成 23 年度から，鈴木紀毅（東北大）と Fabrice Not（CNRS 生態環境研究所）が研究者代表となって，（独）科学技術振興機構（JST）・戦略的国際科学技術協力推進事業の「日本ーフランス（CNRS）研究交流」が始まりました．本研究は、環境ＤＮＡ研究と形態分類学が相互に研究交流を行い、環境応答のための生体分子の構造と機能の１つとして、分子データに乏しい放散虫という海洋プランクトンについて、形態分類と分子分類を統合した参照基盤を作り、過去の環境応答まで応用できる分類学的（遺伝子バーコーディング）および機能的（ゲノムと転写産物）多様性を明らかにすることを目指すものです。
このプロジェクトの一環で，CNRS のカンターパートの研究者が日本に来られます．彼らは新潟大学「形の科学研究センター」が主催する”瀬底プランクトンツアー”に参加して，日本の形態分類技術を提供いたしますが，良い機会なので日本とフランスの研究者で交流するシンポジウムを共同で開催しようという事になりました．
このシンポジウムでは，お互いの研究を紹介しあい，フランス側チームの技術と日本側の技術の効能について意見を交わし，生物学的研究と古生物学的研究の強い協力でどのような明るい未来が放散虫研究に描けるかを模索します．
