Figure 1.
Jumonji demethylases are required for proper H3K4me3 accumulation in response to acclimation (ACC). (a) Schematic representation of the temperature conditions used. Timing of ChIP-seq is denoted by red dots. Above, basal thermotolerance condition; below, heat stress memory condition. (b) Venn diagrams showing the overlap between the genes downregulated in jmjq mutants and the genes with elevated H3K4me3 in the wild type (WT) with and without acclimation compared to the equivalent jmjq mutants (p = 2.3 × 10−17 for elevated H3K4me3). (c) H3K4me3, H3K27me3, and H3 peaks at the regulatory regions of the HSP21 gene in the wild type and jmjq mutants without and with acclimation.
