Table 1. Chl and carotenoids contents of WT and pds2-1 mutant plants.

Arabidopsis	Chl a (mg L−1)	Chl b (mg L−1)	Car (mg L−1)	Chl (mg L−1)	Chl a/b	Chl/Car
WT	19.03±4.60	8.01±1.86	5.17±0.82	27.04±2.76	2.60±0.93	5.29±0.38
pds2-1	0.10±0.01**	0.15±0.01**	0.01±0.00**	0.25±0.01**	0.70±0.03**	20.79±3.25**

Leaves from 40-day-old plants were sampled to determine the Chl and carotenoid contents.

** indicates significant differences of the means at P<0.01 between WT plants and pds2-1 mutant plants for each parameter measured (n = 4).
