Extended Data Fig. 6: Heat stress largely weaken chromatin contact in PLAD and KEE regions.
From: The plant nuclear lamina disassembles to regulate genome folding in stress conditions
a, Comparison of genome-wide wild-type Hi-C contacts (left) and those at chromosome 3 (right). Colors in the left panel indicate the relative changes in chromatin interaction strengths, expressed as the ratio of heat-stressed over mock sample. The inlet highlight chromosome 3. The right panel shows chromosome 3 chromatin contact strengths. The arrowheads highlight interactions between chromosome 3 KEE regions, which are suppressed in heat-stressed plants. b, Comparison of chromatin organization of PLAD regions. Each panel shows chromatin interaction strength of PLAD at one chromosome. The curves describe how fast cis-chromatin contacts decrease as a function of genomic distance. c, Contact patterns of a KEE region in chromosome 3 with the entire genome, whose ___location is indicated with an arrow head (VP, view point). In each panel, KEE regions are highlighted with black dots.
