title: Plant Evolution: What Does It Take To Be an Egg?
abstract: The genetic regulation of cell patterning within plant gametophytes remains poorly understood. Now, two new studies in the liverwort Marchantia polymorpha shed light on the conserved function of an RKD transcription factor as a key regulator of egg cell fate in the land plant lineage.
