An isolated polynucleotide encoding a zinc finger protein is provided, as is the isolated zinc finger protein, peptide portions thereof, orthologs of the zinc finger protein, and antibodies that specifically bind the zinc finger protein. Also provided is a transgenic plant, which contains in its genome a transgene containing the polynucleotide encoding the zinc finger protein, or a nucleotide sequence complementary to the encoding polynucleotide. In addition, methods of identifying a nucleotide sequence and/or a heterologous protein that is specifically bound by the zinc finger protein, methods of using the isolated polynucleotide (or encoded polypeptide), for example, to modulate plant cell growth and/or development, are provided.
