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

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.

Phosphorylation-Dependent Activation of the bHLH Transcription Factor ICE1/SCRM Promotes Polarization of the Arabidopsis Zygote

This study shows that phosphorylation of the bHLH transcription factor SCRM by MPK3/6 promotes zygote polarization in Arabidopsis, contrasting with its role in epidermal cell divisions.
