(A–C) pMGP::MGP:GFP protein fusion expression in WT (A) and inducible RBR overexpressor line before (B) and after transfer for 24 hr (C) to Dex-amethazone (hpDex).
(D–F) pCYCD6;1::GFP fusion expression in WT (D) and in scr4-1;SCRAxCxA (E); note the correlation between expansion of pCYCD6;1::GFP expression domain and appearance of extra ACDs, marked with asterisks; asymmetric segregation of pSCR::SCRAxCxA:YFP in the same plant (F).
(G) ChIP-qPCR using RBR antibody and primers to specific regions of NUC, PCNA, and IR1 promoters. Black asterisks, Student’s t test (p < 0.05); fragment −2.2 showed variable enrichment in biological replicates.
