Fecha de publicación: 21/04/2011 Fuente: WIPO "pollination" A Zea mays regulatory region is shown, 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.
