该研究阐明了ATX1/2-COMPASS-like复合体通过其互作因子JMJ28的WRC结构域特异的识别DNA基序,被招募至靶位点催化H3K4me3修饰的沉积。 由于COMPASS-like复合体之间存在广泛的功能冗余,以及与其他甲基转移酶相比,ATX1/2对H3K4me3的贡献相对较小,导致鉴定出的受JMJ28特定靶向的位点数量并不多。另外,目前尚不清楚JMJ28所识...
进一步研究发现，osashl1 osashl2双突变体中基本营养生长期正调控因子OsVIL4的H3K4三甲基化水平显著降低，致使其转录水平降低，延长基本营养生长期。综上，该研究揭示了COMPASS-like-OsVIL4途径调控水稻基本营养生长期的分子机制，补充了水稻抽穗期调控机制，为育种实践中平衡营养生长与生殖生长提供新思路。COMPASS-like复合...
