Pigment analysis of WT and e8 mutant strain

	Chl/cell (%)	chl a	Chl/car	Vio	Vau	Anthera	Cantha	Zea	β-car
WT	100.0%	100.00	2.31	20.51	12.17	3.56	0.67	3.21	3.27
s.d.	13.8%	5.04	0.17	1.11	0.71	0.48	0.53	0.60	0.31
e8	69.6%*	100.00	2.17	19.14	13.37	3.64	1.03	5.90*	2.97
s.d.	2.5%	9.16	0.18	0.94	0.73	0.50	0.34	1.32	0.38

Chlorophyll content per cell (Chl/cell) was set to 100% in the case of WT. The concentration of pigments in pmol was determined by HPLC and normalized to 100 pmol of chlorophyll a (Chl). Violaxanthin: vio, vaucheriaxanthin: vau, β-carotene: β-Car, antheraxanthin: anthera, zeaxanthin: zea, canthaxanthin: cantha. Standard deviations (s.d.) are reported for the different values (n = 5 for Chl/cell values, n = 3 for the other values). Significantly different values are marked with * if p < 0.05, as determined by unpaired two-sample t-test (n = 3)
