Before auxin distribution matters: Prepatterning of the Arabidopsis embryo axis by MPK6-dependent AUX/IAA8 phosphorylation

Torren Bischoff, Marina Ortega-Perez, Alexa‐Maria Wangler, Helen Schaefer, Martina Kolb, Kai Wang, Houming Chen, Yingjing Miao, Yashodar Babu, Lisa Yasmin Asseck, Laura Ragni, Daniel Slane, Gerd Juergens, Martin J. Bayer

The paper shows that auxin distribution is not required for initial embryonic patterning in Arabidopsis, as differential phosphorylation of AUX/IAA8 by MPK6 sets up the apical-basal axis.
