Nucleic acids that control seed and fruit development in plants

An isolated nucleic acid molecule comprising a polynucleotide that:

• a. specifically hybridizes to SEQ ID NO:1 or SEQ ID NO:6 in a buffer of 40% formamide, IM NaCl, 1% SDS at 37° C., followed by one wash for 20 minutes in 0.2X SSC at a temperature of about 50° C.;
• and
• b. when transcribed in a transgenic plant, enhances endosperm development in the absence of fertilization.
