myb36-1 has more divisions in the meristem and in the differentiation zone than wild type. (A) Wild-type root meristem; the endodermis is outlined in orange (n = 20). (B) myb36-1 mutant root meristem displays additional divisions (outlined in orange) with 75% penetrance (n = 15/20). (C) Optical cross-section of wild-type seedling at the onset of the differentiation zone. Note the stereotypical eight cells present in both the endodermis and cortex. (D) Optical cross-section of myb36-1 at the onset of the differentiation zone. Additional divisions are outlined in orange. (E) myb36-1 has increased endodermal expression of JKD, SCR, and MGP compared with wild type (for source data see Dataset S8). (F) qRT-PCR of MYB36 expression 3 h after induction of pSCR::SCR:GR. Mean expression values of three biological replicates are reported after normalization with PP2A expression. Error bars are SEM (for source data see Dataset S9).
