A and C, Phenotypes of Arabidopsis wild-type (Col-0) and ntrc seedlings growing in SD or LD conditions for 14 d (A) and 30 d (C). B and D, Chl a and b contents of 14- and 30-d-old plants, respectively. The ntrc seedlings show a pale-green phenotype of rosette leaves (arrows) and reduced Chl content. Data are given as means ± sd of three biological replicates. Asterisks denote significant differences from Col-0 with P < 0.05. fw, Fresh weight.
