Axial patterning in leaves and other lateral organs.

Author information

  • 1Section of Plant Biology, University of California Davis, 95616, USA.


The establishment of abaxial-adaxial polarity in lateral organs involves factors intrinsic to the primordia and interactions with the apical meristem from which they are derived. Recent molecular genetic studies have identified some of the genes that promote either adaxial or abaxial cell fates, with many of the genes encoding spatially localized transcription factors.
