報告名称 ゲノム全遺伝子の発現ヒエラルキー決定機構の解明
報告概要 全遺伝子のなかから,どれをどの程度に発現し利用するかを決定する機構の解明が,ポストゲノムプロジェクトの最も重要な研究課題との立場から,本研究が開始された。転写酵素RNAポリメラーゼが,ゲノム全遺伝子から発現遺伝子を選択し,またそれぞれの発現水準を決め,遺伝子間の発現水準の順位を決定していると考えた理論を提唱し,その実証を目指した研究を実施した。研究対象として,主として原核生物の代表大腸菌と真核生物の代表として分裂酵母を解析し,またこのモデルを検証するための最も単純なウイルスを解析した。大腸菌における遺伝子発現ヒエラルキー決定機構の研究,分裂酵母の遺伝子発現ヒエラルキー決定機構の研究およびウイルスにおける遺伝子発現ヒエラルキー決定機構の研究についての研究実施概要を述べた。
