Repression of Apical Homeobox Genes Is Required for Embryonic Root Development in Arabidopsis

Development of seed plant embryos is polarized along the apical-basal axis. This polarization occurs in the absence of cell migration and culminates in the establishment of two distinct pluripotent cell populations: the shoot apical meristem (SAM) and root meristem (RM), which postembryonically give...
