Relative ratios of chloroplast-to-nuclear DNA copy in obgc1-d1 mutants. The relative ratios of chloroplast DNA (rpoA) to nuclear DNA (Actin) copies were normalized to the wild-type values. The copy numbers of rpoA and Actin were determined using qRT-PCR with their gene-specific primers. Black and gray bars indicate the dark- and light-grown plants, respectively. Error bars represent the mean ± SD values calculated from three independent experiments
