Prevalent putative chromatin bivalency and partial resetting of H3K27me3 in plant sperm

How histone modifications are reprogrammed through germline development in plants is poorly understood. We found that H3K27me3 and H3K4me3 are extensively reprogrammed throughout the development of Arabidopsis male gametophyte. This reprogramming leads to widespread chromatin bivalency and selective removal of H3K27me3 marks from key developmental regulators in sperm.

Automated summary

This study reveals the extensive reprogramming of H3K27me3 and H3K4me3 during Arabidopsis male gametophyte development. It leads to widespread chromatin bivalency and selective removal of H3K27me3 marks from key developmental regulators in sperm.
