	Fv /Fm
Lines	Untreated	Nigericin	Water Control
Wild type
HL	0.824 ± 0.007
LL	0.821 ± 0.012	0.823 ± 0.007	0.822 ± 0.002
CP29

^aPlants were grown under HL or LL and dark adapted for 1 hr, and the F_v /F_m was determined directly (means ±sd, n ≥ 8) or after infiltration of leaf discs with nigericin or water (means ±se, ).

^bSignificant difference from the corresponding wild-type parental line (P < 0.001).

^cND, not determined.
