植物ゲノム・遺伝学研究室

わたしたちの研究

わたしたちの研究の目的

 植物はそれぞれ数億〜数千億文字に相当する膨大なゲノム情報をもっていますが、そのすべてが大事な情報であるとは限りません。そこで、わたしたちはさまざまな植物種について膨大なゲノム情報を収集・整理し、その種にとって本当に大事な部分(遺伝子など)がどこにあるかを調べる研究を行っています。さらに、ゲノムや遺伝子の情報を利用して新しい品種を効率よく作り出す方法の開発を進めています。

わたしたちの研究の特徴

 わたしたちは、これまで25種類を超える様々な植物を対象に有用な遺伝子や特徴的な目印(マーカー)を見つけだしてきました。また、トマトやイチゴ、カーネーションなど作物のゲノム解読も行っています。さらに、膨大なゲノム情報から遺伝子を効率的に見つけ出すための解析手法の開発にも取り組んでいます。これらの成果をもとに、国内外の公的機関や企業と共同研究を行い、迅速な品種改良を可能にする育種技術の開発など、ゲノム情報を産業に役立てるための取り組みを行っています。

応用が期待される分野

 ある植物と別の植物、あるいは異なる品種の塩基配列を比較することで、それぞれの植物の特徴を決めている遺伝子をしぼりこむことができます。また、特徴的な遺伝子の働きを明らかにすることによって、病気や干ばつに強い農産物を育種するための基礎的な知識が得られます。このように、ゲノム情報を利用した新たな育種技術が開発できれば、これまでにない優れた性質を持つ新たな品種を作り出すことや、10年以上かかるといわれる品種の育成期間を短縮することが期待されます。また、ゲノム情報を比較することで、長い地球の歴史のなかで植物がどのように進化してきたかを推測し、現在地球に存在する植物の関係を詳細に知ることができます。

研究テーマ

  1. 有用植物の全ゲノム解読
  2.  ゲノム情報が十分でない有用植物の全ゲノム解読を行い、ゲノム解析と育種を行うための基盤を整備します。千葉県が生産額1位(平成26年度)のサツマイモのほか、キク、マメ科3種に取り組みます。また、植物の全ゲノムを安く速く解読するための技術開発を行います。

  3. 有用植物のDNAマーカーと遺伝子型解析技術の開発
  4.  イチゴ、トマト、インゲン、クズ等の有用植物を対象に、全ゲノムを高密度でカバーするDNAマーカーの開発を行います。また、効率良いゲノム再解読法を確立し、有用植物のハプロタイプ地図の作成に取り組みます。

  5. ゲノム情報を活用した育種技術法の開発
  6.  有用形質とマーカーを対応させるための新たな遺伝解析や有用遺伝子領域の高精度なマッピング法を開発するとともに、遺伝子組換え体作出技術の効率化に取り組みます。また、ヤハズエンドウを用いて野生種が栽培種になるまでの過程を模擬実験します。

  7. 大規模配列解析による網羅的な遺伝子機能推定
  8.  トマトやイチゴの果実などで発現している有用遺伝子の網羅的な解析による遺伝子機能の推定を行うために、RNA-seqやマイクロアレイ技術による遺伝子発現解析を行います。また、SNPs(一塩基の変異による多様性)の遺伝子機能への影響を推定するために、SNPsに意味付けする方法の確立に取り組みます。

  9. 育種機関と連携したDNAマーカー選抜の実施
  10. 千葉県農林総合研究センターをはじめとする公的研究機関や種苗会社に所属する育種研究者と協力し、DNAマーカーの開発や、それらを用いた優良個体の選抜を行います。落花生のオレイン酸含量やイチゴの果実表面色の選抜などを行い、付加価値の高い品種の開発に貢献します。
