Outline of Final Research Achievements

In addition to the sequence-based functional annotation, we have attempted to develop a method to infer function from gene expression information. Although available RNA sequencing (RNA-Seq) data varies among species, the developed method, named Fanflow4Insects, can be used as tissue-specific expression information from expression data obtained from RNA-Seq expression quantification analysis, thereby providing a method to infer function from sequence information-based functional annotation. The use of tissue-specific expression information from RNA-Seq expression quantitative analysis has made it possible to provide functional annotation for transcriptional sequences for which no clue could be obtained from sequence-based functional annotation.

Academic Significance and Societal Importance of the Research Achievements

開発した機能アノテーションワークフローFanflow4Insectsは、昆虫のみならず陸上植物のアカシソにおける機能アノテーション手法として利用され、そのゲノム配列解読後にFanflow4Plantsとして得られた遺伝子配列の機能アノテーションに用いた。二次代謝の例としてアントシアニンの合成経路の再構築に応用し、ゲノム中に多コピー存在する酵素遺伝子の同定を行った。このことは開発した手法が今後、非モデル生物の機能アノテーションのみならず、ゲノム編集ターゲット遺伝子選定に寄与し、データ駆動型ゲノム育種に大きく貢献すると考えられる。
