Arabidopsis thaliana and b
Bocconia frutescens fruits. Black, locules; dark green, main carpel vascular bundles; light green, carpel wall; pink, lignified tissue; blue, dehiscence zones; cr commissural ring, se seed, v valve; arrows point to the dehiscence zones in sections. c Immature fruit (6–7 mm diameter) of B. frutescens closed to the left and cut opened to the right. d Mature fruit (1 cm diameter) of B. frutescens, closed to the left and in successive opening stages to the right. Note the ring-like structure remaining after valve separation. This figure has been modified from Pabón-Mora et al.
