The Rice Scutellum: Studies by Scanning Electron Microscopy and Electron Microprobe X-Ray Analysis.

K. Tanaka, M. Ogawa, and Z. Kasai. Copyright 1976 by the American Association of Cereal Chemists, Inc. 

Observations of the rice scutellum using a scanning electron microscope indicated the scutellar cell contains many spherical particles which resemble aleurone particles of the aleurone layer. The distribution of P, Mg, and K in the scutellar cell observed by electron microprobe X-ray analysis is very similar to that in the aleurone cell. Therefore, it is reasonable to conclude that both tissues contain particles characterized by high contents of Mg and K salts of phytic acid.
