- Regulation of fruit dehiscence in Arabidopsis

Fig. 1. The Arabidopsis fruit. Scanning micrograph of a silique shortly after pollination (stage 14, according to Smyth et al., 1990). The different parts of the fruit are indicated. Transverse section of the ovary of a mature silique (stage 17B). A close-up of the boxed area is shown in (C). Section of the dehiscence zone of a stage 17B silique. Lignified cell walls have been traced in pink for clarity, and the fracture surface in the separation layer is noted by a blue line. DZ, dehiscence zone; SL, separation layer; LC, lignified cells at the valve margin mesocarp; ena, endocarpa, already disintegrating in the left valve; enb, endocarpb.

Fig. 2. A model for differentiation and regulation of dehiscence. Genes/activities/relationships backed up by direct evidence are shown in black. Proposed activities and interactions are noted in grey. PG, polygalacturonase; XET, xyloglucan endotransglycosylase; Sl, separation layer cell; LC, lignified cell at the valve margin mesocarp.
