	Wild type	3.08 ± 0.01	1.1 ± 0.02	0.44 ± 0.10	2.81
4 weeks	ygld mutant	2.06 ± 0.16**	0.42 ± 0.10**	0.38 ± 0.01**	4.93
	Wild type	4.15 ± 0.22	1.39 ± 0.05	0.8 ± 0.11	2.98
10 weeks	ygld mutant	2.28 ± 0.24**	0.64 ± 0.18**	0.46 ± 0.01**	3.96

Chl and Car were measured in acetone extracts from second leaf of different growth stages from top. Values shown are the mean SD (±SD) from three independent determinations.
