Table 1. Chlorophyll Levels and Calculated Fluorescence Parameters of Wild-Type and ndc1 Plants Exposed to Continuous High Light Intensity (800 μmol Photons m−2 s−1) for 3 d.

Level or Parameter Wild Type ndc1
Chlorophyll a (nmoles g−1 FW) 1298 ± 38 1057 ± 36a
Chlorophyll b (nmoles g−1 FW) 830 ± 15 693 ± 53b
Fv/Fm 0.726 ± 0.042 0.802 ± 0.038
NPQ 1.010 ± 0.214 1.909 ± 0.429
ϕPSII 0.321 ± 0.072 0.212 ± 0.079

Fluorescence parameters were calculated after 5 min of actinic illumination. Data are means of three (chlorophyll) to four\ (fluorescence parameters) biological replicates ± sd. Different superscript letters indicate significant differences from the wild type as determined by Fisher’s test (P < α = 0.05) from an analysis of variance. FW, fresh weight.
