ABSTRACT = {Understanding the assembly and spatial arrangement of bamboo cell wall components is crucial for its optimal
utilization. Bamboo cell walls consist of aggregates of cellulose microfibrils and matrix. In the present study, the
size and arrangement of cellulose microfibril aggregates in the cell walls of sclerenchyma fibers and parenchyma
cells in moso bamboo were investigated with NMR and FE-SEM. The NMR measurement showed that the characteristic sizes of the microfibril aggregates of fibers and parenchyma cells were approximately 25.8 nm and
18.8 nm, respectively. Furthermore, high-resolution SEM showed the size of microfibril aggregates varied little
across the cell wall of sclerenchyma fiber. However, there were significant size differences between the broad
and narrow lamellae both in fiber and parenchyma cells, which is thought to be closely related to the orientation
of microfibrils in these layers. The microfibril aggregates in the fibers mainly appear in a random arrangement,
although occasionally in a radial or tangential arrangement in individual cell. Parenchyma cells have a relatively
thinner cell wall layers, in which microfibril aggregates appear in a concentric lamellar arrangement.},
