Outline of Final Research Achievements

On the cross section of the stem of the plant, tissues such as epidermis, cortex and endodermis are concentrically arranged from the outside. Radial patterns of such tissues are formed from undifferentiated tissues at the tip of the stem (shoot apical meristem), but their formation mechanisms are hardly elucidated. This research aims to understand the mechanism of radial pattern formation of the stem as a major objective, focusing on endodermis layer of the stem. The research infrastructure for the elucidation of the endodermis formation mechanism of stem was improved by trying to identify the endodermis stem cells in the shoot apical meristem and the genes associated with endodermis formation, through devising research materials and using observation techniques developed recently.
