Table 3. Co-purification of MSI1 with PcG proteins from cross-linked protein extracts.

MSI1–GFP was expressed in Arabidopsis under the control of the MSI1 promoter. Proteins were identified by immunoaffinity purification of MSI1–GFP and mass spectrometry. The experiment was performed with two biological replicates (IP5c-6c) using inflorescences. Shown are all identified plant PcG proteins.
