The establishment of Adaxial-Abaxial polarity of plant leaves is one of the important processes in leaf morphogenesis. ASYMMETRIC LEAVES1/ASYMMETRIC LEAVES2 (AS1/AS2) are key transcription factors that modulate the Adaxial-Abaxial polarity in plant leaf development. These factors are able to cooperate with multiple proteins or miRNAs in the direct or indirect manners, in order to coordinate the development and formation of plant leaves. This review summarized the conserved structural features of AS1/AS2 and their regulatory functions involved in leaf development and morphogenesis, which might provide insights for further deciphering the molecular mechanisms of AS1/AS2.
