Résumé
Adaptation of plants to environmental changes involves the mechanisms of long-distance signaling. In characean algae, these mechanisms comprise the propagation of action potential (AP) and the rotational cytoplasmic streaming acting in cooperation with light-dependent exchange of ions and metabolites across the chloroplast envelope. Both excitability and cyclosis exert conspicuous effects on photosynthetic activity of chloroplasts but possible influence of cyclosis arrest on the coupling of AP stimulus to photosynthetic performance remained unexplored. In this study, fluidic interactions between anchored chloroplasts were allowed or restricted by illuminating the whole internode or a confined cell area (2 mm in diameter), respectively.
