H3K27me3 contributes to pollen germination by enabling chromatin accessibility and expression of VC genes. Upper panel, Photographs of in vitro pollen germination assays. Sperm cells are marked in red and REF6-GFP delineate VCs (adapted from Huang and Sun [2022], Figure 2). Lower panel, Model for H3K27me3-mediated VC differentiation (adapted from Huang and Sun [2022], Figure 7; nucleosome images are licensed CC-BY 4.0 and freely available at bioicons.com). Pollen: grey, VC: blue, and SC: dark yellow.
