Paper Abstract

The red (R) and far-red (FR) light irradiation were shown to induce Ca2+ concentration oscillations in cytoplasm of oat protoplasts. The inhibitors of Ca2+ pumps, sodium vanadate and 2,5-di-tert-butyl-1,4-benzohydroquinone (tuBHQ) influence these oscillations. The trigger of Ca2+ oscillations is Ca2+ release from endoplasmic reticulum and vacuole but not mitochondria. The manifestation of regular Ca2+ oscillations depends on the concentrations of oat protoplasts in suspension that suggests the propagation of a signal between the cells and synchronization of their light- induced Ca2+ oscillations response.
