Outline

Dormancy and Adaptation Research Unit
Our unit studies the mechanisms that regulate plant adaptation responses such as seed dormancy, germination and stress responses. We will reveal how biosynthesis and transport of plant hormones such as abscisic acid, gibberellin, jasmonates and auxin are regulated. We will optimize plant adaptation responses by genetic and chemical regulation of hormone transport and biosynthesis.

Subjects

  1. Identification and functional characterization of plant hormone transporters
  2. Identification of metabolites involved in plant growth and stress responses
  3. Identification of factors involved in seed dormancy, germination and longevity
  4. Development of a system to quantify plant metabolites from a single cell
Identification of an abscisic acid transporter AIT1

(a) Surface temperature of inflorescence stems in wild type and ait1

(b) Stomatal aperture of inflorescence stems in wild type and ait1
Promoter activity of AIT1
(a) Seedlings (b) Inflorescence stems
