TranscriptomicsGenome-wide expression analysis in kyp and cmt3 mutants of Arabidopsis thaliana
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 re...

ProteomicsMBD8 is required for LDL2-mediated transcriptional repression downstream of H3K9me2 in Arabidopsis
Histone H3 lysine 9 methylation (H3K9me) is a conserved epigenetic mark for transcriptional gene repression. In Arabidopsis, H3K9 dimethylation (H3K9me2) promotes the removal of a transcription-associated mark, H3K4 monomethylation (H3K4me1), and this process within genes requires the histone demeth...

TranscriptomicsGenome-wide analysis of H3K9me2 in ibm1, kyp, and cmt3 mutants of Arabidopsis thaliana
In diverse eukaryotes, constitutively silent sequences, such as transposons and repeats, are marked by methylation at histone H3 lysine 9 (H3K9me). Despites the conservation and importance in the genome integrity, mechanisms to exclude H3K9m from active genes remained largely unexplored. Here we sho...

TranscriptomicsExpression data in Arabidopsis axe1-5 and met1-3 mutants.
We applied the tiling arrays to study the Arabidopsis whole-genome transcriptome in Arabidopsis axe1-5 and met1-3 mutants. Fifteen-day-old Arabidopsis plants grown on the agar plates were harvested. The total RNA was prepared from 15-day-old Arabidopsis plants (axe1-5 (hda6 mutant), DR5 (parental li...
