第4回生物学国際高等コンファレンス（OBC4) が9月10-15日に開催された。私は今回初めて参加させていただいたが、OBC は比較的少人数( 参加者約60人、約半数が外国人) で行われるセミ・クローズドの会議ということで、フレンドリーな雰囲気の中で、非常に密度の濃い会議であった。 タイトルのTerra Microbiology は地球微生物学とでも訳すのだろうか、地球生態系における微生物のはたらきを、微生物による物質代謝と循環、微生物間の相互作用、進化といった切り口で解明するといった、壮大な目標を掲げた会議である。窒素代謝に焦点を当てた物質循環のセッション、quorum sensing の機構に焦点を当てた細菌間のクロストークのセッション、遺伝子の水平伝達に焦点を当てた微生物進化のセッションの3セッションから 構成されており、特定のテーマにあえてフォーカスし、その中で多様な切り口の研究発表を揃えるといった工夫がなされていた。たとえば、個人的に関心があった水平移動のセッションでは、フィールド調査に基づく遺伝子動態の話、ウィルスに着目したメタゲノム解析の話、水平遺伝子移動を可視化する技術の話、網羅的な解析に基づく系統推定の話など、多様な話が聞けた。幅広いテーマについて、バラバラに論ずるのではなく、深く掘り下げた議論ができるように構成されており、また参加者が少人数で厳選されていることもあって、全ての発表できわめて活発な討論が行われたことも印象的であった。 最終日にはメタゲノム解析、メタプロテオミクス解析などに関連する、新しい技術の発表があった。こうした技術が、今後この分野にどのようなインパクトをもたらすかについては、まだ意見の相違もみられたが、ゲノム技術に裏打ちされたフロンティア分野として、さらなる発展が期待される分野であることは間違いない。今回は実験系の人の発表が大半であ ったが、今後は理論系の人の参入も期待される。そういう印象を持った会議であった。 （内山 郁夫）
