Figure 5.

Carpel wall cross-sections illustrating the degree of carpel expansion and development from an anthesis-stage pistil compared with 7-DPA unpollinated, pollinated, and PGR-treated siliques from the gai and Ler backgrounds. a, Anthesis-stage Ler pistil; b, unpollinated Ler pistil; c, pollinated Ler silique; d, Ler silique induced with 10 μmol GA₃ pistil⁻¹; e, Ler silique induced with 10 μmol NAA pistil⁻¹; f, pollinated gai silique. Unmarked arrowheads indicate dehiscence zones; X, exocarp; M, mesocarp; T, supportive sclerenchyma; N, endocarp; S, seed; O, ovule; P, septum; F, funiculus; R, replum. Scale bar = 250 μm.
