Expression Patterns of PUCHI.

(A) to (C) Wild-type inflorescence apices.

(A) PUCHI mRNA is detected on the adaxial side of the stage 1 flower primordium.

(B) PUCHI mRNA is detected on the adaxial side of the stage 2 flower primordum.

(C) Localization of GFP-PUCHI fusion protein expressed under the cis-regulatory elements of the PUCHI gene. The fusion protein is detected on the adaxial side of stages 1 and 2 floral meristem proper.

(D) Fourteen-day-old wild-type seedling apex that has just begun bolting. PUCHI mRNA is detected in the rosette and cauline leaf axils.

(E) PUCHI mRNA is detected in the axillary meristems of cauline leaves. Numbers indicate stages of flower development (Smyth et al., 1990).

rl, rosette leaf; cl, cauline leaf; st, stem. Bars = 50 μm.
