Dataset Summary

Title	Identification of interactors of Arabidopsis VIN3 and VRN5 proteins in vernalized seedlings
Description	The Arabidopsis VEL proteins VIN3 and VRN5 are accessory proteins of the Polycomb Repressive Complex 2 (PRC2). Their function is most well-understood in the epigenetic PRC2-mediated silencing of the floral repressor gene Flowering Locus C (FLC) during prolonged cold (vernalization). To identify protein interactors of VIN3 and VRN5, also dependent on their C-terminal VEL domains, we used stable Arabidopsis transgenic lines expressing VIN3-GFP WT, VIN3-GFP deltaVEL, VRN5-SYFP2 WT and VRN5-SYFP2 deltaVEL under endogenous promoters to perform native co-immunoprecipitation assays in seedlings vernalized for six weeks at 5 °C. Non-transgenic Col-FRI was used as a negative control.
