Contrasting epigenetic dynamics in chromosome arms and pericentromeres during ROS1-induced plant immune memory [ONT-seq]

ABSTRACT: Induced resistance against (hemi-)biotrophic pathogens can be triggered in Arabidopsis by 17β-estradiol (E2)-dependent activation of ROS1 in plants carrying the XVE:ROS1-YFP transgene. Here, we use long-read Oxford Nanopore Technologies sequencing (ONT-seq) and the centromere-complete Arabidopsis genome assembly Col-CEN to characterise genome-wide changes in DNA methylation associated with the establishment of ROS1-mediated resistance, with a particular focus on pericentromeric and centromeric regions.

Contrasting epigenetic dynamics in chromosome arms and pericentromeres during ROS1-induced plant immune memory [BiSulfite-seq]

Project description:Induced resistance against (hemi-)biotrophic pathogens can be triggered in Arabidopsis by 17β-estradiol (E2)-dependent activation of ROS1 in plants carrying the XVE:ROS1-YFP transgene. Here, we characterise the genome-wide cytosine DNA methylation changes associated with the estbalishment of this ROS1-mediated resistance.

Nanopore sequencing of estradiol and DMSO treated XVE:ROS1-YFP plants

Project description:Transgenic plants carrying an estradiol-inducible ROS1-YFP construct (XVE:ROS1-YFP) were subjected to long-read sequencing (Oxford Nanopore Technologies) to assess the global impacts of ROS1 activity on the methylome of Arabidopsis thaliana (ecotype Col-0).

small RNA profiling of WT, ros1-4, nrpd1 single mutants and ros1-4/nrpd1doubble mutant [small RNA-seq]

Project description:Arabidopsis ROS1 is the first genetically characterized DNA demethylase in eukaryotes. Dysfunction of ROS1 leads to increase in DNA methylation level at thousands of genomic loci. However, the features of ROS1 targets are not well understood. In this study, we identified and characterized ROS1 target loci in Arabidopsis Col-0 and C24 ecotypes. Most ROS1 targets are transposable elements (TEs) and intergenic regions. Compared to other TEs, ROS1-targeted TEs are closer to protein coding genes, suggesting a role for ROS1 in preventing the spreading of DNA methylation from highly methylated TEs to nearby genes. Interestingly, we found that unlike general TEs, ROS1 targets are associated with an enrichment of H3K18ac and H3K27me3, and depletion of H3K27me and H3K9me2. We investigated the antagonism between ROS1 and RNA-directed DNA methylation (RdDM) by identifying and characterizing thousands of genomic regions regulated by both ROS1 and RdDM. Unexpectedly, we uncovered thousands of previously unidentified RdDM targets by analyzing the DNA methylome of ros1/nrpd1 double mutant plants. In addition, we show that ROS1 also antagonizes RdDM-independent DNA methylation at more than a thousand genomic loci. Our results provide significant insights into the genome-wide effects of both ROS1-mediated active DNA demethylation and RNA-directed DNA methylation as well as their interaction in plants.

mRNA-seq of ros1-3 and ros1-4 with ABA treatment

Project description:To survey transcriptome changes by the mutations of a DNA demethylase ROS1 responding to a phytohormone abscisic acid, we performed the Next-gen sequencing (NGS) associated RNA-seq analysis. Two ROS1 knockout lines (ros1-3, ros1-4; Penterman et al. 2007 [PMID: 17409185]) with the wild-type Col line (wt) were subjected. Three samples (ros1-3, ros1-4 and wt), biological triplicates, ABA or mock treatment, using Illumina HiSeq 2500 system

SIZ1-mediated SUMOylation of ROS1 Enhances Its Stability and Positively Regulates Active DNA Demethylation in Arabidopsis

Project description:The 5-methylcytosine DNA glycosylase/lyase REPRESSOR OF SILENCING 1 (ROS1)-mediated active DNA demethylation is critical for shaping the genomic DNA methylation landscape in Arabidopsis. Whether and how the stability of ROS1 may be regulated by post-translational modifications is unknown. Using a methylation-sensitive PCR (CHOP-PCR)-based forward genetic screen for Arabidopsis DNA hypermethylation mutants, we identified the SUMO E3 ligase SIZ1 as a critical regulator of active DNA demethylation. Dysfunction of SIZ1 leads to hyper-methylation at approximately one thousand genomic regions. SIZ1 physically interacts with ROS1 and mediates the SUMOylation of ROS1. The SUMOylation of ROS1 is reduced in siz1 mutant plants. Compared to that in wild type plants, the protein level of ROS1 is significantly decreased, even though there is an increased level of ROS1 transcripts in siz1 mutant plants. Our results suggest that SIZ1 positively regulates active DNA demethylation by promoting the stability of ROS1 protein through SUMOylation.
