Our exciting data show that embryonic patterning in Arabidopsis is kick-started by differential sensitivity towards auxin and not by differential distribution of auxin.

Before auxin distribution matters: Prepatterning of the Arabidopsis embryo axis by MPK6-dependent AUX/IAA8 phosphorylation
In growth and development of plants, the signaling molecule auxin plays an instrumental role. Many patterning processes are controlled by auxin signaling in a self-organizing matter. After fertilizati...
