Outline of Final Research Achievements

Using near-isogenic lines with the same genetic background of functional and unfunctional FTB1 gene, which is thought to have an effect on the ripening period of soybean, I determined which stage of the developmental process from flowering to maturity the FTB1 gene affects. Some alleles were identified using the soybean mini-core collection. In developing the genetic materials, I also worked on the development of genotyping methods.

Academic Significance and Societal Importance of the Research Achievements

ダイズの成熟期間は収穫期や生産量だけでなく、種子の品質にも関わる重要な形質である。今回の解析により、FTB1は当初予想されていた種子の成熟期間を制御するのではなく、開花後の全てのステージを遅らせる機能があることが明らかとなった。今までに開花までの形質には関与せず、開花以降のステージのみを遅らせる機能を持つ遺伝子は知られておらず、機能的に興味深い。また開花期には影響しないため、収穫期の短縮に向けた育種ターゲットになり得る。
