Decreased levels of chloroplast rRNAs in the ppr287 mutant. Total RNA extracted from 1-week-old Col-0, ppr287 mutant, amiRNA knockdown mutant (KD1), and complementation line (Com1) was separated on a 1.2% formaldehyde agarose gel, and the levels of the processed products were determined by Northern blot analysis using the probes represented by thick lines below each gene; three probes for rrn23 are labeled with (a), (b), and (c). Relative intensities of rRNA bands in each sample were calculated, and the values under each lane are mean ± SD of three replicates
