Suzuki et al. compared the RNA editing events of 8 genes (atp1, atp4, atp6, atp8, atp9, cox1, cox2, cox3) in the mitochondria from sterile lines, maintainer lines, and restorer lines and found that the relationship between sterility and fertility restoration cannot be explained by RNA editing analysis of these genes [55]. This evidence concerns the gene MT-ATP6 and infertility disorder.
