Sample	Band 2	Band 3	Band 4
Wild type	276.50 ± 5.90	252.38 ± 8.59	117.71 ± 4.58
npq1	297.40 ± 3.39*	273.58 ± 2.93*	109.69 ± 0.66
npq2	219.18 ± 4.80*	218.07 ± 2.97*	121.62 ± 2.99

Band 2, monomeric Lhcb proteins; band 3, trimeric LHCII complex; band 4, PSII core complex. Data are the average of four independent measurements. The chlorophyll concentration was 0.1 μg/mL. Data sets with a significance level of P < 0.05 according to Student's t test are marked with an asterisk.
