Similar Expression Patterns of GATA3 Family Genes in the Arabidopsis Flowers, as Detected by in Situ Hybridization.

The expression domains of HANL2 ([A] to [E]), GNC ([F] to [J]), and GNL ([K] to [O]) are overlapping during wild-type flower development. Longitudinal sections of shoot apices ([A], [F], and [K]), stage 4 flowers ([B], [G], and [L]), stage 6 flowers ([C], [H], and [M]) and stage 8 flowers ([D], [I], and [N]) reveal that GATA3 family genes are expressed throughout the IM and young floral primordia (stages 1 to 3) and then limited to the inner three whorls (petal, stamen, and carpel). Transverse sections reveal that GATA3 family genes are specifically expressed in the anther locules, vascular strands, and ovules ([E], [J], and [O]). Arrow indicates the strong expression of GNC in the ovules within the ovary. Bars = 50 µm.
