Have you ever wondered how the epigenome is modified during the transition from seed to seedling? Here, we show that water uptake by Arabidopsis seeds triggers the eviction of the H2B variant H2B.8, thereby revealing replication-independent chromatin reprogramming. www.nature.com/articles/s41...

The transition from seed to seedling requires chromatin reprogramming. By studying the histone variant H2B.8, the authors show that it organizes silent chromatin in dry seeds and reveal that water upt...

Have you ever wondered how new DNA methylation patterns are established? Paradigm shift ahead! We discovered a new mode of DNA methylation targeting in plants that relies on transcription factors and sequence motifs rather than chromatin modifications to regulate the methylome. rdcu.be/eQ6L5 1/8
