「季節時計の進化」
カレンダーを持たない生物が、どのように季節の変化を感知して、環境の季節変化に適応しているかは、有史以来の謎であり、人類は長らくこの謎に惹きつけられてきた。また、地球温暖化などによる急激な気候変動が生態系に及ぼす影響も心配されており、社会的な関心も大きい。
近年の研究によって、植物や動物が季節を感知する仕組みについて理解が進んだことで、生物の季節感知機構についての普遍性や多様性が見えてきた。このような背景をふまえ、第64回基生研コンファレンスは“Evolution of Seasonal Timers”と題して、生物の季節感知機構の設計原理と進化について理解を深めることを目的として開催された。
「季節」をキーワードとしていたものの、話題はフィールドにおける野生植物の開花の数理解析から、ウナギの回遊・産卵の仕組み、リスの冬眠、あるいはクロマチンリモデリングや化学遺伝学など、多岐にわたった。それぞれの分野で世界を先導する研究者が国内外から集ったが、参加者が100名程度と最適な規模であったため、３日間にわたって全員が顔と顔を突き合わせて、濃密な議論を繰り広げることができた。普段の学会では絶対に顔を合わせることのないメンバーが一同に会したため、学際的な視点から季節感知機構について深く考えなおす機会となり、今後の研究に向けて多くのインスピレーションを得ることができた。参加者からも”most stimulating symposium I ever had”や”unforgettable symposium”などのお言葉をいただくことができた。
このカンファレンスの運営にあたりご尽力いただいた国際連携室と季節生物学研究部門のメンバー、ならびにサポートしていただいた基生研、大幸財団、Human Frontier Science Programに感謝の意を表したい。
