Summary
Barley roots fixed with OsO4 containing potassium pyroantimonate showed the presence of several types of electron opaque precipitates in the cells. Thin sections were cut from a region about 1 cm from the root tip and the electron opaque deposits analysed using EMMA-4 with KEVEX Si(Li) energy dispersive analyser. Antimony-containing deposits at the root surface associated with the mucilaginous sheath were found to contain Fe and P, and count ratios suggest constant proportions of these elements in the precipitates. Within the root cells, vacuolar deposits generally contained Os and Sb, but occasional deposits in epidermal cell vacuoles contained some Fe. Fe was also detected in nuclear deposits in endodermal cells.
These findings are discussed briefly in relation to the uptake of Fe into plant roots.
