--- _id: '9459' abstract: - lang: eng text: Nucleosome remodelers of the DDM1/Lsh family are required for DNA methylation of transposable elements, but the reason for this is unknown. How DDM1 interacts with other methylation pathways, such as small-RNA-directed DNA methylation (RdDM), which is thought to mediate plant asymmetric methylation through DRM enzymes, is also unclear. Here, we show that most asymmetric methylation is facilitated by DDM1 and mediated by the methyltransferase CMT2 separately from RdDM. We find that heterochromatic sequences preferentially require DDM1 for DNA methylation and that this preference depends on linker histone H1. RdDM is instead inhibited by heterochromatin and absolutely requires the nucleosome remodeler DRD1. Together, DDM1 and RdDM mediate nearly all transposon methylation and collaborate to repress transposition and regulate the methylation and expression of genes. Our results indicate that DDM1 provides DNA methyltransferases access to H1-containing heterochromatin to allow stable silencing of transposable elements in cooperation with the RdDM pathway. article_processing_charge: No article_type: original author: - first_name: Assaf full_name: Zemach, Assaf last_name: Zemach - first_name: M. Yvonne full_name: Kim, M. Yvonne last_name: Kim - first_name: Ping-Hung full_name: Hsieh, Ping-Hung last_name: Hsieh - first_name: Devin full_name: Coleman-Derr, Devin last_name: Coleman-Derr - first_name: Leor full_name: Eshed-Williams, Leor last_name: Eshed-Williams - first_name: Ka full_name: Thao, Ka last_name: Thao - first_name: Stacey L. full_name: Harmer, Stacey L. last_name: Harmer - first_name: Daniel full_name: Zilberman, Daniel id: 6973db13-dd5f-11ea-814e-b3e5455e9ed1 last_name: Zilberman orcid: 0000-0002-0123-8649 citation: ama: Zemach A, Kim MY, Hsieh P-H, et al.
