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...
Rare earth elements (REEs) influence many physiological processes in plants, but the mechanism is still unknown. The question of whether REEs can enter plant cells is crucial in assessing the biological effects of REEs. In this paper, a method for determination of REE lanthanum (La) in ultratrace level in cell contents of giant algal cells was established. The uptake and subcellular distribution of...
