In the original article, there was a mistake in Figures 4A–C and Figure 5A as published. The figures depicting DNA methylation underrepresented the true DNA methylation in our samples and in maize in general. The underlying computation made use of the average DNA methylation in 100 bp tiles. However, there were tiles that either had no DNA methylation sites or had no read calls at existing DNA methylation sites. Instead of disregarding these instances, tiles with non-existent values were used in the original computation as the value “0%.” We now removed any instances of tiles with unknown or absent DNA methylation information. Due to the different likelihoods of these instances in different contexts, substantial differences in the calculated DNA methylation percentage occurred in the CG context, less in the CHG and almost none in the CHH context (H=A, T, or C). The higher DNAmethylation percentages in the corrected graphs agree with other maize DNA methylation data. The correction did not change the previously described qualitative outcomes. The corrected Figures 4A–C and Figure 5A appear below. The following sections have been updated correspondingly. In addition, since two of the authors changed institutions by now, their new affiliations are listed in the author section of this corrigendum. (Figure presented.).
