Expression pattern of OsWOX3A.
(A, C) Detection of GUS expression under the control of the OsWOX3A promoter (ProOsWOX3A::GUS) in 3-day-old elongating shoot in (A) and 1-week-old young seedling in (C). (B) Cross section of elongating shoot showing GUS expression in coleoptile, leaf primordia, and vasculature. (D) Magnified view of the bottom of leaf sheath in red rectangle in (C). (E) GUS expression in a 2-month-old node, elongating node (left) and young panicle node (right). col, coleoptile; IN, internode; L2, 2nd leaf; L3, 3rd leaf; LB, leaf blade; LS, leaf sheath; ND, node; PN, panicle node;. Scale bars = 1mm (A), 0.2mm (B), 4mm (C), 2mm (D, E). These experiments were repeated more than twice with similar results.
