Schematic models describing the role of VIN3 in vernalization response. A, Before vernalization, FLC is actively transcribed and enriched with H3K4me3 (active) mark. By vernalization, H3K4me3 is decreased, and H3K27me3 is substantially increased by VIN3-containing PRC2 complex. B, Before vernalization, VIN3SW is capable of binding to H3K4me3-enriched FLC chromatin. VIN3SW protein enhances the PRC2 activity at FLC chromatin during vernalization and results in an accelerated vernalization response.
