Outline of Final Research Achievements

The B (b) locus was thought to be located on chromosome 10. The A (a) locus was found to be on chromosome 7. Based on these results, the hypothesis that a plant has two loci A (a) and B (b) both carrying dominant genes grows abnormally. In addition, using CAPs markers candidate gene for B gene was supposed to locate within 2,445,537 bases. Among them, 12 genes highly expressed in shoot apical meristems of abnormal individuals, and most of which were involved in disease resistance.

Academic Significance and Societal Importance of the Research Achievements

園芸学は品種の拡大を通じて、食の多様化に貢献してきた。一方で品種育成の目指すべきポイントは徐々に細かな形質改変に向けられており、大きな変革は起こしにくくなっている。これを打破するための一つの手段として種間交雑が挙げられる。種間交雑を行うためにはその遺伝的障壁を打破する必要がある。この研究では、トウガラシの種間交雑障壁が2遺伝子で決まっていることを明らかにした。
