The FWA cis‐regulatory sequence drives expression in the central cell and syncytial endosperm. The FWA promoter fragment is sufficient to restrict dFWA‐GFP and 3XVENUS expression to the central cell in the mature female gametophyte, and to the syncytial endosperm after fertilization. GFP and 3XVENUS are targeted to the nucleus with the N‐terminal homeodomain fragment of the FWA protein that contains a nuclear‐targeting sequence and an NLS, respectively. Scale bar: 50 μm (shown only in the upper left‐hand panel).
