Abstract excerpt

The Arabidopsis ENHANCER OF PINOID (ENP) protein and the AGC-kinase PINOID (PID) synergistically impact on polarization and function of the auxin transporter PIN-FORMED1 (PIN1) required for plant leaf and flower organ development. ENP offers a PID-independent input for PIN-function since enp pid double mutants lead to cotyledon- and flower-less plants in contrast to pid single mutants, which develop cotyledons...
