The initiation and maintenance of CHH methylation and its effects on gene expression are unique in maize (small RNA-Seq)

To determine the causes of changes in methylation during hybridization, we investigated small RNAs, particularly 24 nt small interferring RNAs (siRNAs) at the differentially methylated regions. We compared the small RNA expression between two parents (B73 and Mo17), between parents and wild type F1 (WTF1), and between WTF1 and mop1 mutant F1 (mop1F1). Overall design: Comparative small RNA expression analysis of small RNA sequencing data for for parents, WTF1, and mop1F1.
