“To remember or forget: Insights into the mechanisms of epigenetic reprogramming and priming in early plant embryos”
Chromatin is dynamically modified throughout the plant life cycle to regulate gene expression in response to environmental and developmental cues. Although such epigenetic information can be inherited across generations in plants, chromatin features that regulate gene expression are typically reprogrammed during plant gametogenesis and directly after fertilization. Nevertheless, environmentally induced epigenetic marks on genes can be transmitted across generations. Moreover, epigenetic information installed on early embryonic chromatin can be stably inherited during subsequent growth and influence how plants respond to environmental conditions much later in development. Here, we review recent breakthroughs towards deciphering mechanisms underlying epigenetic reprogramming and transcriptional priming during early plant embryogenesis.
