Targeted DNA demethylation of the Arabidopsis genome using the SunTag-dCpf1-TET1cd system

ABSTRACT: DNA methylation is a stable and heritable epigenetic mark, and it plays an important role in regulation of gene expression and transposon silencing. Here we developed a CRISPR/dCpf1-based targeted demethylation system using the catalytic domain of the human demethylase TEN-ELEVEN TRANSLOCATION1 (TET1cd) and a SunTag system. The SunTag-dCpf1-TET1cd system is able to achieve targeted DNA demethylation and ur-regulate gene expression when guided to the FWA or CACTA1 loci in Arabidopsis thaliana. Our study provides tools for targeted removal of DNA cytosine methylation, and activation of protein-coding genes or transposons expression.

Targeted DNA demethylation of the Arabidopsis genome using the Human TET1 catalytic domain.

Project description:DNA methylation is important for silencing genes and transposable elements. Changes in DNA methylation can be heritable and thus, the loss or gain of methylation can lead to the formation of stable epialleles. A well characterized example of a stable epiallele in plants is fwa-4, which consists of the loss of DNA cytosine methylation (5mC) in the promoter of the FLOWERING WAGENINGEN (FWA) gene, causing upregulation of FWA and a heritable late flowering phenotype. Here we demonstrate that a fusion between the catalytic domain of the Human demethylase TEN-ELEVEN TRANSLOCATION1 (TET1cd) and an artificial zinc finger (ZF) designed to target the FWA promoter can cause highly efficient targeted demethylation, FWA upregulation, and a heritable late flowering phenotype. Additional ZF-TET1cd fusions designed to target methylated regions of the CACTA1 transposon also caused targeted demethylation and changes in expression. Finally, we have developed a CRISPR/dCAS9 based targeted demethylation system using the TET1cd and a modified SunTag system and demonstrate its ability to target demethylation at and activate the expression of FWA and CACTA1. Our study provides tools for targeted removal of 5mC at specific loci in the genome with high specificity and minimal off-target effects. These tools provide the opportunity to develop new epialleles for traits of interest, and to reactivate expression of previously silenced genes, transgenes, or transposons.

Site-specific manipulation of Arabidopsis loci using CRISPR-Cas9 SunTag systems

Project description:Understanding genomic functions requires site-specific manipulation of loci via efficient protein effector targeting systems. However, few approaches for targeted manipulation of the epigenome are available in plants. Here, we adapt the dCas9-SunTag system to engineer targeted gene activation and DNA methylation in Arabidopsis. We demonstrate that a dCas9-SunTag system utilizing the transcriptional activator VP64 drives robust and specific activation of several loci, including protein coding genes and transposable elements, in diverse chromatin contexts. In addition, we present a CRISPR-based methylation targeting system for plants, utilizing a SunTag system with the catalytic domain of the Nicotiana tabacum DRM methyltransferase, which efficiently targets DNA methylation to specific loci, including the FWA promoter, triggering a developmental phenotype, and the SUPERMAN promoter. These SunTag systems represent valuable tools for the site-specific manipulation of plant epigenomes.

DNA epigenome editing using CRISPR-Cas SunTag-directed DNMT3A [WGBS]

Project description:We demonstrate that dCas9-SunTag-DNMT3A dramatically increased CpG methylation at the HOXA5 locus in human embryonic kidney 293T cells (HEK293T). Furthermore, using a single sgRNA, dCas9-SunTag-DNMT3A was able to methylate a 4.5 kb genomic region and repress HOXA5 gene expression. Reduced representation bisulfite sequencing (RRBS) and RNA-seq showed that dCas9-SunTag-DNMT3A methylated regions of interest with minimal impact on the global DNA methylome and transcriptome.

Active DNA Demethylation by DNMT3A and DNMT3B - Mechanistic Aspect and In Vivo Evidence

Project description:The DNA methylation program is at the bottom layer of the epigenetic regulatory cascade of vertebrate development. While the methylation at C-5 position of the cytosine (C) residues on the vertebrate genomes is achieved through the catalytic activities of the DNA methyltransferases (DNMTs), the conversion of the methylated cytosine (5mC) could be accomplished by the combined actions of the TET enzyme and DNA repair. Interestingly, it has been found recently that the mouse and human DNMTs also possess active DNA demethylation activity in vitro in a Ca2+- and redox condition-dependent manner. We report here the study of tracking down the fate of the methyl group removed from 5mC on DNA during in vitro demethylation reaction by mouse de novo DNMTs, i.e. DNMT3A and DNMT3B. Remarkably, the methyl group becomes covalently linked to the catalytic cysteines utilized by the two de novo DNMTs in their DNA methylation reactions. Thus, the forward and reverse reactions of DNA methylations by the DNMTs may utilize the same cysteine residue(s) as the active site despite of their distinctive pathways. Secondly, we demonstrate that active DNA demethylation of a heavily methylated GFP reporter plasmid by ectopically expressed DNMT3A or DNMT3B occurs in vivo in transfected human HEK 293 cells in culture. Furthermore, the extent of DNA demethylation by the DNMTs in this cell-based system is affected by Ca2+ homeostasis as well as by mutation of their putative active cysteines. These findings substantiate the roles of the vertebrate DNMTs as double-edged swords in DNA methylation-demethylation in vitro as well as in a cellular context.
