Structure and Mineral Composition of Cereal Aleurone Cells as Shown by Scanning Electron Microscopy.

Scanning electron microscopy revealed basic similarities in structures of aleurone cells in barley, oats, rye, and wheat. The cell wall(s), the plasmalemma, and the interior of the aleurone cell wall were investigated. The aleurone grains are embedded in a network, which occupies the intergrain spaces. Various organelles and protrusions are confluent with the surface of the aleurone grain. Aleurone grains contain substantially greater quantities of mineral components than the aleurone cell wall. Relative concentrations of mineral components point to the presence of a potassium-magnesium, rather than a calcium-magnesium, salt of phytic acid as the main form of phosphorus in the aleurone grains of barley.
