Bivalent histone modifications regulate gene expression during development, but little is known about their function in plant–microbe interactions. In a recent report, Zhao et al. showed that expression of bivalent chromatin-marked gene 1 (BCG1), containing a pathogen-associated molecular pattern (PAMP) motif, is epigenetically regulated by trimethylation of lysine 4 (H3K4me3) and lysine 27 (H3K27me3) of histone H3 to evade plant immunity.

二价组蛋白修饰：植物病原体如何逃避植物免疫

二价组蛋白修饰在发育过程中调节基因表达，但对其在植物-微生物相互作用中的功能知之甚少。在最近的一份报告中，赵等人。研究表明，含有病原体相关分子模式 (PAMP) 基序的二价染色质标记基因 1 ( BCG1 ) 的表达受到组蛋白 H3 赖氨酸 4 (H3K4me3) 和赖氨酸 27 (H3K27me3) 三甲基化的表观遗传调控，从而逃避植物免疫。
