Summary

In the prothallus of the fernAdiantum capillus-veneris, which consists of a single cell-layer, nuclear position differs depending on light and dark conditions. Under white light, nuclei are located along the cell wall facing the light source (light-position). In contrast, in the dark, nuclei are located at the walls partitioning the cells (dark position). The change from light- to dark-position takes about 36 h, but the change from dark- to light-position takes less than 8 h.
