Abstract

Biological and environmental effects of lanthanide series of elements have received much attention recently due to their wide applications. In this study, effects of La³⁺ treatments on calcium and magnesium concentrations as well as cytoplasmic streaming of internodal cells of Chara corallina were investigated. At all treatment concentrations (10, 100, and 1,000 μM), La³⁺ significantly decreased calcium concentrations in the cell-wall fractions after 5-h treatments. Calcium concentrations in the cell contents and magnesium concentrations in the cell-wall fractions were reduced by 100 and 1,000 μM La³⁺ treatments. However, cytoplasmic streaming as an indicator of [Ca²⁺]_cyt was only inhibited at the highest La³⁺ concentration (1,000 μM). The results suggest that La ³⁺ may affect cellular calcium homeostasis by actions other than as a simple Ca²⁺ antagonist. La³⁺ could partially compensate for calcium deficiency at certain concentrations.
