Research Topics
  • Function of brassinosteroids on agriculturally important traits

    My main focus in this research program is on the genetic improvement of crop production. One target trait is erect leaves, as this trait has benefits for plants in terms of improved light capture for photosynthesis, nitrogen use for grains, and the possibility of denser plantings with a higher leaf area index, all of which can increase crop yield. Brassinosteroids regulate the angle of upright leaves in rice, and I previously demonstrated that the brassinosteroid-related erect leaf phenotype increases biomass and grain production in rice. Brassinosteroids also enhance various aspects of crop production in rice, such as disease resistance and abiotic stress tolerance. To achieve genetic improvement of crops, I wanted to understand the relationship between brassinosteroids and genetic network regulating these agriculturally important traits.

  • Improvement of sweet potato production

    Sweet potato is an important crop in Ishikawa Prefecture, especially a line derived from cultivar ‘Kokei 14’, grown in sandy fields within the limited area of Kanazawa City. This line is well known throughout Japan as the “Gorojima Kintoki” brand. In contrast, a β-carotene containing orange-flesh cultivar developed in Ishikawa Prefecture, ‘Kenroku’, is expected to be a new special product of Ishikawa Prefecture. In this research program, I wanted to improve yield, quality and shelf stability of these two sweet potato cultivars.
