Figure 3. Quantitative RT-PCR (qRT-PCR) expression of CYC2-like genes for the parallel floral morphologies in the Old World Malpighiaceae Tristellateia australasiae (A) Acridocarpus natalitius (B) and Sphedamnocarpus pruriens (C).

Figure 3

Grayscale shading on floral diagrams summarizes the relative strength of the spatial pattern of CYC2 expression in the corolla and calyx. qRT-PCR expression data was determined for dissected floral organs at mid and late stages. Expression levels are relative to the control β-tubulin. Error bars represent standard errors. ds, dorsal sepal; ls, lateral sepal; vs, ventral sepal; dp, dorsal petal; lp, lateral petal; vp, ventral petal; st, stamens; ca, carpels; MB, medium buds ∼40–60% of full size buds; LB, large buds ∼70–90% of full size buds. Scale bars equal 5 mm.
