Phenotypic characterization of Arabidopsis <i>cgl160</i> mutant plants.

<p>A. Top panel shows, from left to right, a wild type plant, <i>cgl160-1</i> and wild type, <i>cgl160-2</i> plants grown for 3 weeks under normal light conditions (120 μmol m^-2 s^-1) at long day (16 hours light and 8 hours dark). B. Wild type, <i>cgl160-1</i> and <i>cgl160-2</i> plants grown under short day conditions (120 μmol m^-2 s^-1; 8 hours light and 16 hours dark) for 4 weeks. C. Shows, from left to right, a wild type plant, <i>cgl160-1</i> and wild type, <i>cgl160-2</i> plants grown for 1 week under normal light conditions (120 μmol m^-2 s^-1) at long day (16 hours light and 8 hours dark) and then shifted to fluctuating low/normal light conditions (5 min 120 μmol m^-2 s^-1, 5 min 20 μmol m^-2 s^-1 changing every 5 min for 16 hours light and then 8 hours dark) for two weeks. D. Bar graph of Fv/Fm as a measure of photosynthetic performance under the indicated conditions.
