At3g15170: CUC1 (CUP-SHAPED COTYLEDON1)

Encodes a transcription factor involved in shoot apical meristem formation and auxin-mediated lateral root formation. The gene is thought not to be involved in stress responses (NaCl, auxins, ethylene). Cuc mutant was first recognized at the heart stage, where embryos lacking two distinct bulges of cotyledonary primordia were observed.
