Ution buffer (1 Triton X-100, 2 mM EDTA, 20 mM Tris-HCl at pH eight.1, 150 mM NaCl) and immunoprecipitated once more by anti-FLAG (the second ChIP). The recovered DNA was purified and quantified by qPCR. Relative enrichment fold was calculated by normalizing the amount of a target DNA fragment against that of a genomic fragment of a reference gene TUB8, and after that against the respective input DNA samples. The enrichment of a PP2A genomic fragment was utilised because the damaging handle. The primers employed are listed in Supplementary Table 1. Transient expression assay. To produce the ABI5:GUS reporter construct, B1.eight kb ABI5 promoter was cloned into HY107 containing GUS gene36.
