“…S 4 ). Bivalent H2A.Z/H3K4m2/H3K27m3 marks, which are frequently associated with stress-memory genes [ 43 ], were found in the promoters of the POLV-regulated NLR gene CSA-1 and the defense related gene LURP1-LIKE . The promoter of the JMJ14-regulated defense-related gene RPW8 also showed induction and repression states.…”

“…While bivalent chromatin associates with poised regulatory elements, causality has not been shown and this structure may simply represent competing chromatin-regulatory processes at these sites. We are not aware of any ‘readers’ of bivalent chromatin in mammalian systems, although these have been discovered in plants [ 130 ]. Moreover, while bivalent chromatin is generally devoid of DNA methylation, how this seemingly incompatible layer of chromatin-based information shapes and is shaped by the bivalent chromatin landscape remains to be disentangled mechanistically.…”
