NR activity state in light or darkness in different A subunit mutant plants. Wild-type Col, the double-mutant pp2aa2 pp2aa3, WS, and rcn1 mutant were tested. Leaves of rosette stage plants were harvested daily during 6 d, 1.5 to 3 h into the light period, and after approximately 12 h of darkness. A, Light samples. B, Dark samples. n = 13, se is given. To test changes in activity stage during light/dark transitions samples were harvested from rosette stage plants 3 h into the daily light period (time 0), light was turned off, and samples were harvested after 2 h of darkness. Light was then switched on, and samples taken after 20 and 40 min of light. C, Double-mutant pp2aa2 pp2aa3 and control wild-type Col. D, rcn1 mutant and control WS. The data are means of four independent experiments, se is given.
