Table 1. Chlorophyll Content and State Transition Parameters of the Wild Type, nsi, and stn7.

Plant Line	Chl a+b (µg/mg)a	Chl a/bb	Fv/Fmc,d	qTe,f	qSg,h
Wild type	1.32 ± 0.11 (n = 27)	3.50 ± 0.14	0.79 ± 0.04 (n = 4)	0.10 ± 0.01	0.80 ± 0.02
nsi-1	1.34 ± 0.12 (n = 27)	3.44 ± 0.13	0.81 ± 0.01 (n = 4)	0.01 ± 0.01	0.23 ± 0.03

stn7	1.26 ± 0.11 (n = 14)	3.36 ± 0.10	0.82 ± 0.01 (n = 4)	−0.01 ± 0.01	0.08 ± 0.04

Differences between genotypes were tested with ANOVA (Supplemental File 1). All data were normally distributed, apart from the stn7 qT parameter, and variances were homogenous. Multiple comparisons were done with Tukey HSD. Averages ± sd are shown, and n is marked in parentheses.

^aANOVA, P = 0.079.

^bANOVA, P = 0.005. Multiple comparisons: wild type versus nsi-1, P = 0.322; wild type versus nsi-2, P = 0.025; wild type versus stn7, P = 0.009; nsi-1 versus nsi-2, P = 0.649; nsi-1 versus stn7, P = 0.264; nsi-2 versus stn7, P = 0.820.

^cANOVA, P = 0.294.

^dF_v/F_m = (F_m-F₀)/F_m.

^eANOVA, P = 1.493×10⁻⁸. Multiple comparisons: wild type versus nsi-1, P = 1.168 × 10⁻⁷; wild type versus nsi-2, P = 1.852 × 10⁻⁷; wild type versus stn7, P = 2.151 × 10⁻⁸; nsi-1 versus nsi-2, P = 0.953; nsi-1 versus stn7, P = 0.216; nsi-2 versus stn7, P = 0.094.

^fqT = (F_m1-F_m2)/F_m1, where F_m1 and F_m2 are the maximum fluorescence yields after illumination causing state 1 and 2, respectively.

^gANOVA, P = 1.385 × 10⁻¹². Multiple comparisons: wild type versus nsi-1, P = 2.266 × 10⁻¹¹; wild type versus nsi-2, P = 3.052 × 10⁻¹¹; wild type versus stn7, P = 2.512 × 10⁻¹²; nsi-1 versus nsi-2, P = 0.894; nsi-1 versus stn7, P = 0.007 × 10^–2; nsi-2 versus stn7, P = 0.027 × 10⁻³.

^hqS = (F_S1′-F_S2′)/(F_S1′-F_S2), where F_S1' and F_S2' are fluorescence yields in the beginning and at the end, respectively, of illumination causing state 2, and F_S2 is fluorescence yield immediately after switching on illumination causing state 1.
