Abstract

Light-stimulated transmembrane potential changes have been measured continuously after implantation of microelectrodes into subepidermal cells of the short-day plant Lemna paucicostata 6746. Irradiation for 5 min with white or red light caused a transient hyperpolarization. These potential changes could be suppressed with 10(-6) M DCMU. Irradiation of DCMU-inhibited plants with far-red light for 5 min hyperpolarized the membrane potential, which thereafter was not changed by further far-red application. Consecutive red light irradiation for 5 min depolarized the membrane potential. The red/far-red reversibility of the potential changes (which could be repeated several times with a single plant) suggests the participation of phytochrome.
