Calcium localization in oat aleurone cells using chlorotetracycline and X-ray microanalysis.
Calcium distribution was studied in oat caryopses. Using the chlorotetracycline method it was found that membrane-associated Ca(2+) was present in the aleurone layer. X-ray microanalysis confirmed the presence of calcium in aleurone cells; it also demonstrated the presence of considerable amounts of calcium in the cell wall surrounding these cells.
