Research Abstract	主に分子生物学的手法を用いて栽培種とその近縁野生種を比較研究し、栽培種の分子遺伝的特性を明らかにすることを目的に、以下の概要のような3項目の研究を実施した。 A)栽培種と近縁野生種のDNAライブラリ-の作成とその利用-コムギでゲノミック(n)DNA,cDNA,ミトコンドリアDNAのライブラリ-を構築した。イネ、コムギ、サツマイモの3属ではnDNAまたはcDNAのクロ-ンを、またテンサイ属では葉緑体DNAのクロ-ンを用いて、栽培種とそれぞれの近緑野生種のRFLP分析を行い、系統関係を明らかにした。イネでは、さらにRFLP地図と遺伝子地図の対応関係を決定した。 B)生産性の基礎をなす形質の研究-イネ、コムギ、ソラマメ、エンドウの4属の栽培種と祖先種の間でrDNAの構造と活性を比較研究し、コピ-数、スペ-サ-の構造及び転写活性の違いを明らかにした。光合成に関しては、栽培タバコの光化学系I複合体タンパク質遺伝子psaDの産物の2分子種の提供親を同定し、トウモロコシではC3、C4及び根型のPEPC遺伝子の構造を決定して、3者の翻訳領域が高い相同性をもつことを証明した。エンドウでは光応答の弱い葉緑体オペロンを発見した。 C)栽培種にとって重要な形質の研究-種子の発芽と休眠に関しては、その生理学的挙動を解析するとともに、コムギで休眠胚に特有なmRNAを見出した。貯蔵タンパク質に関しては、イネで3種タンパク質のそれぞれについて2〜4種のcDNAの構造を決定し、各種タンパク質に固有なシグナルペプチドを同定した。サツマイモのスポラミン遺伝子の発現調節の研究から、器官の肥大とタンパク質遺伝子の発現は無関係であることが証明された。アブラナ科植物を用いて、葉の老化に伴って出現するmRNAを単離し、そのcDNAの構造解析を行い、発現に調節機構を明らかにした。また、熱ショックタンパク質遺伝子の発現条件を解明した。
