Novel mRNAs 3′ end-associated cis-regulatory elements with epigenomic signatures of mammalian enhancers in the Arabidopsis genome

Chromatin signatures in the region flanking the EASE genomic locus and the IGV visualization of the EASE locus. The accumulation of HMM posterior probability (as a measurement of total ChIP-chip signal intensity) for each ChIP-chip data set (±200-bp the EASE genomic locus). (A) Histone H3K4 mono- and trimethylation. Statistically significant (*) P < 0.05, two-tailed paired t-test. (B) Histone H3K27 acetylation and trimethylation. Statistically nonsignificant (n.s.), P = 0.43269, two-tailed paired t-test. (C) IGV visualization of the EASE locus and the ±200 bp flanking region. The signal intensity of H3K4 methylation (mono-, di-, and tri-), acetylation and trimethylation of H3K27, and RNA Pol II occupancy are shown.
