The 36th NIBB Conference "Stress Signaling and Stress Responses in Plants"

Organizers Norio Murata
Venue National Institute for Basic Biology, Okazaki , 444-8585, Japan
Date Jan. 9-11, 1996
第 36 回基礎生物学研究所コンファレンス「植物におけるストレスシグナリングとストレス応答」は当該分野の最新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。近年、植物の環境ストレスに対する応答機構の研究が盛んに行われるようになった。その結果として、環境ストレスのシグナルの伝達機構がいくつかの先駆的な研究によって明らかにされつつあり、シグナル伝達物質としてカルシウムが注目を集めている。また、ストレス応答の結果として得られるストレス耐性の分子機構も明らかにされつつある。そこで本コンファレンスでは、ストレスシグナルの伝達物質としてのカルシウムの研究分野とストレス耐性の研究分野の融合をはかり、新たなアイディアと研究分野を産み出すことを目的とした。国際的雰囲気に包まれて進行したこの試みは成功をおさめ、終始活発な討論や情報交換がなされ、さらにその後の国際共同研究を産み出している。また内外の参加者からは多くの賛辞が寄せられた。参加者は国外から 18 名、国内から 22 名、基礎生物学研究所から 30 名であった。
