Mitochondrial C to U editing events analyzed in each mutant by direct cDNA sequencing. Editing levels are estimated for each gene in percentage related to the peak sizes (shown in Figures S6–S8). Arabidopsis mitochondrial nucleotide editing events analyzed are indicated by their position in the transcript sequence.
