Abstract and Introduction, p. 857: separation versus lignified layers, early ind-mutant cell-division defect, auxin response and tissue-targeted PID/WAG2 expression during stages 14–16. Distinguish early specification from the previously reported late auxin minimum.

Kasper van Gelderen investigates how developmental signals shape plants. He coauthored a 2016 study of INDEHISCENT, auxin response and formation of the separation layer in Arabidopsis thaliana fruits. Comparing normal and altered fruits connected a regulatory gene with the local cell divisions that establish a controlled opening site.[ref]
The study distinguished early tissue specification from later fruit dehiscence. Altering auxin transport during early stages prevented the normal developmental outcome, showing why the time of a perturbation matters as well as its location.[ref] A signal that has one role while a tissue is forming need not have the same role when the mature tissue opens.
