Studying the seed pod of Arabidopsis, Ferr{\'a}ndiz et al. now identify some of the signals that differentiate valve cells from margin cells. A negative interaction between the FRUITFULL and SHATTERPROOF genes ensures that cells in a narrow strip along the edge of the valve acquire characteristics such that a particular zone of the seed pod (the dehiscence zone) can break to release seeds. Dehiscence, as well as lignification, which is also regulated by FRUITFULL, are important agronomic traits. Ferr{\'a}ndiz, C., Liljegren, S.J., and Yanofsky, M.F.
