Protonemata of the fern Adiantum capillusveneris L., grown as single-cell filaments under continuous red light, were irradiated with a narrow beam of blue light. Only irradiation of the region containing the nucleus induced cell division. Beams of 30 ΞΌm in width, which corresponds to the diameter of

β¦ Synopsis
The influence of red and far-red irradiation on the transport of H(+) and (86)Rb(+) through the plasmalemma was studied using parenchymal protoplasts isolated from Vicia faba leaves. The results indicate that red light stimulates H(+) secretion and the uptake of (86)Rb(+). Moreover, it has been demonstrated that far-red irradiation acts antagonistically with respect to red light in both these processes.
