The molecular-genetic cues that regulate plant embryo pattern formation are the subject of intense scrutiny at present. Recent work in Arabidopsis implicates the TOPLESS protein in auxin-dependent transcriptional repression, highlighting once again the crucial role of auxin signaling during embryogenesis.
