While the ways of H\n                    <jats:sub>2<\/jats:sub>\n                    O\n                    <jats:sub>2<\/jats:sub>\n                    disposal in chloroplasts are mostly known, the influence of H\n                    <jats:sub>2<\/jats:sub>\n                    O\n                    <jats:sub>2<\/jats:sub>\n                    on photosynthetic electron transport received less attention. According to various reports, H\n                    <jats:sub>2<\/jats:sub>\n                    O\n                    <jats:sub>2<\/jats:sub>\n                    indirectly promotes electron transport on the acceptor side of photosystem I and activates cyclic electron transport (CET). Here the microinjection technique and PAM microfluorometry were applied to study the influence of H\n                    <jats:sub>2<\/jats:sub>\n                    O\n                    <jats:sub>2<\/jats:sub>\n                    on linear and cyclic electron flows in internodal\n                    <jats:italic>Chara<\/jats:italic>\n                    cells. First, the cells loaded with a fluorogenic ROS\u2010sensitive probe DCF were used to show that microinjection of H\n                    <jats:sub>2<\/jats:sub>\n                    O\n                    <jats:sub>2<\/jats:sub>\n                    is followed by rapid intracellular penetration of H\n                    <jats:sub>2<\/jats:sub>\n                    O\n                    <jats:sub>2<\/jats:sub>\n                    and its distribution with the streaming cytoplasm. Next, the regulatory influence of H\n                    <jats:sub>2<\/jats:sub>\n                    O\n                    <jats:sub>2<\/jats:sub>\n                    on electron transport was examined in chloroplasts with unimpaired and short\u2010circuited H\n                    <jats:sup>+<\/jats:sup>\n                    flows. Linear electron transport (LET) was assessed with a Microscopy PAM fluorometer, whereas the inference on CET was based on measurements of the post\u2010illumination rise of the chlorophyll fluorescence yield. The local application of H\n                    <jats:sub>2<\/jats:sub>\n                    O\n                    <jats:sub>2<\/jats:sub>\n                    was followed by a temporary development of non\u2010photochemical quenching (NPQ). In chloroplasts uncoupled with nigericin, the NPQ development after H\n                    <jats:sub>2<\/jats:sub>\n                    O\n                    <jats:sub>2<\/jats:sub>\n                    microinjection was eliminated, while the polarity and amplitude of H\n                    <jats:sub>2<\/jats:sub>\n                    O\n                    <jats:sub>2<\/jats:sub>\n                    \u2010induced\n                    <jats:italic>F<\/jats:italic>\n                    \u2032 fluorescence changes were reverted and enhanced, respectively.
