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.

This paper identifies a phosphorylation mechanism controlled by the ERECTA receptor and auxin signaling that regulates stem cell activity and vascular cell differentiation in plants.

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.
