| Περίληψη: | Internodal cells of Characeae exposed to flickering spotted illumination mobilize long-range interchloroplast communications between the point of local light stress and non-treated cell areas. The signaling and functional coordination between immobile chloroplasts involves the export of excess products from light-stressed plastids, the lateral transport by the streaming cytoplasm, the entry of delivered substances to dimly lit recipient chloroplasts, and metabolic responses to the entered agents. There is indirect evidence that interchloroplast communications are mediated by two types of metabolites produced during photosynthetic electron transport: reducing agents such as NAD(P)H and the product of oxygen reduction H (Copyright © 2026 Elsevier B.V.
