| Research Abstract |
In order to examine intercellular signaling systems working in organ formation and development, we took several approaches. We identified small LTP proteins in apoplastic extracts of cauliflower heads having a role of formation and maintenance of shoot apical meristem. Genetic approach revealed that trimeric G-protein is involved in the intracellular signing pathway under the peptide hormone receptors that regulate shoot and root meristem function. We showed novel group of tyrosine-sulfated glycopeptides had important roles as intercellular signals in plant development. We investigated action of microRNA165/166 in forming the boundary between the adaxial- and the abaxial-regions in developing leaves. In addition, we developed instrumental systems inducing specific gene(s) in a single plant cell or inactivating a single cell by use of laser beams
