Expression levels of genes involved in chloroplast biogenesis. Expression levels of genes associated with the first and second (a) and third (b) steps of chloroplast biogenesis in wild-type and asl4 mutant seedlings at the L3 stage. Data are means ± SD of three independent repeats. ** and *, indicate significance at P = 0.01 and P = 0.05, respectively, by Student’s t tests
