SOD7 and DPA4 are required for proper CUC2 and CUC3 expression in CaAM. A–D, Maximum projections of tangential optical sections of developing CaAMs of WT and dpa4-2 sod7-2 plants harboring the pCUC2:erRFP and pCUC3:erCFP reporters during CaAM development at the dome stage. E and F, Schemes showing the 3D structures of the apex with the SAM, the cauline leaf primordium (clp) and the developing CaAM. Schemes of the expression patterns of CUC3 are shown. The schemes of the optical sections are shown below. Scheme E corresponds to (B), scheme F to (D). G–J, Maximum projections of tangential optical sections of developing CaAMs expressing the pCUC2:erRFP and pCUC3:erCFP reporters in the WT and dpa4-2 sod7-2 backgrounds during CaAM development at the leaf primordia stage. K–R, Maximum projections of tangential optical sections of whole mount in situ hybridization of CUC2 and CUC3 transcripts in WT and dpa4-2 sod7-2 during CaAM development at the dome stage (K–N) and leaf primordia stage (O–R). Plants were grown for 4 weeks in SD conditions and then shifted to LD. Scale bars = 50 µm. The dotted lines correspond to outlines of the meristems and leaf primordia.
