ABSTRACT:
A regulatory region is shown, a nucleotide sequence of approximately 3kb which provides improved seed preferred, and particularly embryo preferred expression in plants. Methods of use are also shown in preferentially expressing a heterologous protein to the embryo tissue of a plant. The sequence is particularly useful in expression of heterologous proteins to the embryo of monocotyledonous plants, particularly cereals, and maize.
