Research Abstract

オーキシンによる伸長成長機構を明らかにするために、オーキシンによる偏差成長を起こさないmsgクラスの突然変異体msg2とmsg3をオーキシン塗布法と屈地性検定によって単離した。また、T-DNA挿入による変異体msg1-4を単離し、同変異体には複数のT-DNAが挿入されていることを明らかにし、その中の一つのT-DNA挿入部位周辺の塩基配列を決定した。オーキシン作用機構研究のもう一つの方向としてオーキシン誘導体遺伝子(ARG)の発現制御機構と遺伝子産物の機能を解析しているが、ARG1とARG2についてはプロモーター領域とレポーター遺伝子の融合遺伝子をヤエナリ組織に一過的に導入してそのオーキシン誘導性を調べたところ、約1.5倍の誘導性が観察された。ARG8とARG9についてはプロモーター領域のクローニングをおこなった。タバコのARGであるarcAはGβ遺伝子族の遺伝子であるが、同遺伝子産物と相互作用するタンパクのcDNAをクローン化したところK^+チャンネルのβサブユニットに似たタンパクをコードしていた。タバコの3種類のARGの転写調節機構を調べたところ、その制御はそれぞれ異なるシス・トランス因子によることが分かり、オーキシンによる発現調節機構が複合的であることが分かった。エチレン作用に関しては、ACC合成酵素とACCオキシターゼ遺伝子族の発現をメロン果実の成長・成熟過程をおって果実の組織ごとに調べたところ、同遺伝子には果実・成熟過程で時期および組織特異的に発現している特定のメンバーが存在することが分かった。ジベレリン作用に関しては、αアミラーゼ遺伝子プロモーターを用いた機能解析によって、ジベレリンと糖によって制御される因子群の概略を明らかにしたほか、ジベレリン結合タンパクを約10,000倍濃縮し、SDS-PAGEで25kDa付近に目的とするタンパクと思われるバンドを検出した。
