Abstract:     The present invention provides nucleic acid sequences from LEAFY COTYLEDON1 (LEC1) genes encoding LEC1 polypeptides which comprise a CCAAT binding factor domain and which modulate embryo development in plants. The nucleic acids are useful in inducing ectopic development of embryonic tissue or in modulating embryo development in transgenic plants.
