The 34th NIBB Conference "Responses of The Photosynthetic Apparatus to Environmental Light Conditions"

Organizers Norio Murata
Venue National Institute for Basic Biology, Okazaki , 444-8585, Japan
Date Dec. 10-12, 1994
第 34 回基礎生物学研究所コンファレンス「光合成機構の光環境への応答」は、当該分野の最近の研究成果について高度な討論をするために企画された。過去 10 年間において光合成の光環境に対する研究は著しい進歩をとげ、この分野に関する多数の論文が発表されている。しかしながら、これらの研究は有機的なつながりを持つことなく独立に発展してきたもので、今まで、総合的に論じられることが少なかった。そこで、第 34 回コンファレンスでは、異なる研究手法、あるいは、異なる研究の立場を持つ研究者を一堂に集めて、光合成機構の光環境への応答について総合的に討論することを主目的とした。この企画は成功をおさめ、活発な討論を通じて参加者が多くの成果を挙げ、満足して帰国の途についた。参加者は国外から 16 名、国内から 42 名、基礎生物学研究所から 25 名であった。3 日間の会議は国際的雰囲気に包まれて進行した。
