Bisulfite-seq of the Solanum lycopersicum sulfurea paramutation in the cmt3 mutant background and upon reintroduction of WT CMT3

ABSTRACT: Whole genome bisulfite sequencing was done in F3 plants resulting from a cross between Solanum lycopersicum plants bearing the sulfurea epiallele and cmt3 mutants. 6 F3 plants were sequenced: 3 WT and 3 cmt3. The F3 WT plants had methylation levels (quantified with McrBC-qPCR) consistent with the TAB2sulf epiallele and the cmt3 plants had methylation levels consistent with TAB2+ (low DNA methylation). cmt3 mutants from the F2 generation were backcrossed with WT cv M82 plants to restore CMT3 activity and followed for 2 generations (BC2). 4 BC2 plants were sequenced 2 WT and 2 cmt3. The aim of the experiment was to compare DNA methylation levels in all contexts between cmt3 and WT F3 plants with particular interest on SlTAB2 (Solyc02g005200) which has been previously associated with paramutation in the sulfurea background. The stability of DNA methylation upon CMT3 reintroduction was assessed in the BC2 plants. WT cv M82, cmt3 and sulfurea controls were added in single replicates.

smallRNA-seq of Solanum lycopersicum bearing the sulfurea epiallele in nrpe1 versus WT

Project description:Plants bearing a sulfurea epiallele (TAB2sulf) were crossed with nrpe1 (largest polV subunit) mutants in Solanum Lycopersicum. 7 plants of a F3 progeny expected to be 100% TAB2sulf and segregating for the nrpe1 mutation were sequenced. 4 plants bear the nrpe1 mutation and 3 plants have NRPE1 WT alleles. The aim of the experiment was to compare sRNA accumulation between nrpe1 and WT F3 plants with particular interest on SlTAB2 (Solyc02g005200) which has been previously associated with paramutation in the sulfurea background. Both WT and nrpe1 F3 plants had methylation levels consistent with the TAB2sulf epiallele. nrpe1 and sulfurea parental controls are added in single replicates and a WT cv M82 plant is also sequenced as control. More replicates of WT and M82 are sequenced in a related experiment.

Genome-wide expression analysis in kyp and cmt3 mutants of Arabidopsis thaliana

Project description:Investigation of genome-wide expression in the mutant of histone H3K9 methyltransferase KRYPTONITE (KYP) or DNA methyltransferase CHROMOMETHYLASE3 (CMT3) in Arabidopsis. These mutants showed decrease in H3K9 methylation and DNA methylation levels, and transcriptional activation at transposons and repeats. Using NimbleGen DNA microarray, global pattern of expression of genes and transposons were examined in these mutants.

Expression data from Arabidopsis leaves after gamma irradiation of 200 Gy

Project description:Arabidopsis cmt3 mutant showed neither DNA hypomethylation nor transcriptional activation of silenced repeats by gamma rays, which was found in wild type (WT). We used microarrays to compare the global transcriptional changes between the WT and cmt3 after the irradiation of 200 Gy. Transcriptions of transposition-related genes seemed to be differently affected in the WT and cmt3 by gamma rays, depending on the epigenetic codes of the genome. However, genome-wide transcriptions of the WT and cmt3 couldn't be positively correlated with the different levels of DNA methylation after the irradiation of 200 Gy. Rosette leaves from more than 10 plants were pooled for total RNA extraction and hybridization on Affymetrix Arabidopsis ATH1 genechips. We performed two independent array experiments using totally different biological replicates of WT and cmt3 mutant plants with or without gamma irradiation.

Identifying crossover locations in Arabidopsis thaliana CMT3-11 (Col) x CMT3-7 (Ler) F2 and wild type Col x Ler F2 populations using genotyping by sequencing

Project description:Genomic DNA from 384 CMT3-11 (Col) x CMT3-7 (Ler) F2 and 171 wild type Col x Ler F2 individuals was extracted using CTAB and used to generate sequencing libraries as described (Rowan et al; Yelina et al), with the following modifications. DNA was extracted from 3 rosette leaves of 5 week old plants and 150 ng of DNA used as input for each library. DNA shearing was carried out for 20 minutes at 37C with 0.4U of DNA Shearase (Zymo research). The barcoded adapters used for library construction are listed in Rowan et al. Each set of 96 libraries was sequenced on one lane of an Illumina NextSeq500 instrument (300-cycle Mid Output run). Sequencing data was analysed to identify crossovers as previously reported, using the TIGER pipeline (Rowan et al; Yelina et al).
