Development of chloroplast structure and photosynthetic competence in dark adapted moss protonemata after exposure to light

Protoplasma 89(3-4): 359-369

Development of chloroplast structure and photosynthetic competence in dark adapted moss protonemata after exposure to light

Sporelings and protonemata of Ceratodon purpureus were grown in darkness for 1-2 mo. On their exposure to light, starch was observed after 30 min but only minor changes occurred in the chloroplast structure during the 1st hours. After 1 day in light, the chloroplasts had a structure similar to that of the chloroplasts of light-grown material. The dark-grown material evolved O2 and assimilated CO2 readily after exposure to light. Maximization of the photosynthetic rate was not achieved until the 2nd day in light, coinciding with the development of light-type chloroplasts. The ultrastructural localization of photosystems [PS] I and II revealed much higher activity of PS I in dark-adapted material than in material grown in light, but the activity of PS II appeared to be greater in light-grown material.
