Representative patterns of secondary cell-wall lignin deposition in the endocarp b tissue for different species of the Brassicaceae family (as indicated) that are considered by explosive (Cardamine) and non-explosive silique shattering. Bottom: Mature wild-type fruit. Phylogenetic relationships connecting species are shown in the cladogram. Top: Light microscopy transverse valve section of fully grown fruit with cell walls stained with toluidine blue

Indehiscent or non-shattering trait is one of the evolutionary significant event of crop domestication. In wild taxa, dehiscence is vital for the propagation of progeny and their adaptation under diverse growth conditions. Dispersing seeds from the maternal parent is essential, as greater distances generally amplify offspring success due to the ava...

... few studies, the lignification patterns in the silique of Cardamine hirsuta, a relative of Arabidopsis that is considered by explosive seed shattering. There is strong asymmetric lignin deposition in the endocarp b cell walls of the fruit valves as accountable for the explosive seed shattering during silique opening ( Figure 2). It was projected a model in which these "hinged cells" were required to store the mechanical tension that was required for the valve twisting. ...
