Fig. 6. In situ STY (A,C,E,G) and GRAM expression patterns (B,D,F,H) in wild-type inflorescences. The longitudinal sections are consecutive in B-F and G-H. (A,B) mRNA expression patterns. (CH) Protein expression revealed by immunolocalisation. P0 indicates the youngest bract (b) primordium and numbers indicate floral developmental stages (Carpenter et al., 1995). The complementary pattern of STY and GRAM expression is illustrated in G,H. stg, stigma; st, style; cw, carpel wall; o, ovules. Scale bars: 200 µm (A,B,E-H); 100 µm (C,D).
