Outline of Final Research Achievements

I have found that there is a nano-periodic differences in physical property in the secondary cell wall, using a scanning probe microspe. This neno-periodic property difference may be due to the diurnal cell wall formation. The 3D laser scanning confocal microscope visualized the concentric cell wall stripe structure with the strength of the reflected laser intensity. The reflection intensity can be involved by the interference caused distribution of cellulose microfibril and matrix components in cell wall. The scanning prob microscope revealed that the layered structure was clearer in the cell wall differentiated under the long-night condition.

Academic Significance and Societal Importance of the Research Achievements

これまで明らかにされてなかった細胞壁二次壁の超微細構造の一端を示して細胞壁の理解を深めた。細胞壁は優れた生物材料である。形成の機序と完成した細胞壁の構造との関係が明らかになったことは、生育条件によって細胞壁の構造を制御できる可能性を示したことを意味する。木質科学研究において形状解析レーザー顕微鏡、走査型プローブ顕微鏡、イオン液体電子顕微鏡を利用知識の蓄積に貢献した。
