Abstract

Root identity in plant embryos During Arabidopsis embryogenesis, a single cell — called the hypophysis — is specified to become the founder cell of the root meristem in response to signals from adjacent cells. Hypophysis specification requires an auxin responsive transcription factor, MONOPTEROS, which promotes transport of auxin from the embryo to the hypophysis precursor. In this study, Dolf Weijers and colleagues identify MONOPTEROS target genes and show how they mediate root formation.
