摘 要:Polycomb group(PcG) proteins are crucial epigenetic regulators conferring transcriptional memory to cell *** assemble into multi-protein complexes,e.g.,Polycomb Repressive Complex 1 and 2(PRC1,PRC2),which are thought to act in a sequential manner to stably maintain gene ***2 induces histone H3 lysine 27(H3K27) trimethylation(H3K27me3),which is subsequently read by PRCl that further catalyzes H2A monoubiquitination(H2Aub1),creating a transcriptional silent chromatin ***2 components are conserved in plants and have been extensively characterized in *** contrast,PRCl composition and function are more diverged between animals and *** more recently,PRC1 existence in plants has been *** we review the aspects of plant specific and conserved PRC1 and highlight critical roles of PRC1 components in seed embryonic trait determinacy,shoot stem cell fate determinacy,and flower development in Arabidopsis.
