Floral Morphology of A. vulgaris clm and in Situ Hybridization of AqvAP3-1, AqvAP3-2, AqvAP3-3, and AqvPI in clm Floral Meristems.

(A) Photograph of a flower from the underside. All perianth organs have the morphology of sepals (inset shows adaxial epidermis).

(B) to (D) Histological sections of developing floral meristems. Arrowheads indicate second whorl organs.

(E) and (F) AqvAP3-1.

(G) AqvAP3-2 with inset showing earlier stage.

(H) AqvAP3-3.

(I) to (L) AqvPI.

Sections in (B), (C), and (E) are tangential longitudinal, while those in (D) and (F) to (L) are radial longitudinal. Arrowheads indicate second whorl primordia, unless stated otherwise. Bars = 100 μm.
