Molecular genetic application of hyperspectral image sensing as a method for high-throughput quantitative phenotype analysis

要旨:生物科学の研究では、材料やスケールを問わず、対象物を見分ける必要に迫られることが多い。その際、私たち が最も頻繁に参照する形質は、言うまでもなく目に見える形や色である。しかしながら、私たちはこれらの情報を十分 に活用できているだろうか。とりわけ色に関しては、定量的な情報として注意深く扱われていることは稀である。一方、 衛星や航空機によるリモートセンシングでは、精密な色情報とも言える分光特性が、地上にある対象物を定量または識 別するための主要な鍵情報として活用されている。筆者らは、高精細な分光データを保持することができるハイパース ペクトル画像を、ノイズの少ない撮影条件と遺伝的に均質なモデル植物の利点を生かすことのできる実験室において活 用することにより、組織または細胞レベルの生理的状態を精度よく予測するための実験系の構築に取り組んでいる。本 稿では遺伝学研究にリモートセンシングの異分野技術を取り入れる試みを紹介するが、生態学における同技術の新たな 活用法を案出する有用な手がかりとなることを願いたい。 特 集 植生のリモートセンシング
