The normal development of lateral organs of the shoot requires the simultaneous repression
of meristem-specific genes and the activation of organ-specific genes. ASYMMETRIC
LEAVES2 (AS2) is required for the development of normal leaf shape
and for the repression of KNOX genes in the leaf. AS2 is a member
of the recently identified, plant-specific LATERAL ORGAN BOUNDARIES (
LOB)-domain gene family. Expression of AS2 at high levels resulted
in repression of the KNOX homeobox genes BREVIPEDICELLUS, KNAT2
, and KNAT6 but not of the related SHOOT MERISTEMLESS gene.
Overexpression of AS2 also led to a perturbation of normal adaxial-abaxial
asymmetry in lateral organs, resulting in the replacement of abaxial cell types with
adaxial cell types. These results indicate that AS2 is sufficient to induce
adaxial cell fate and repress KNOX gene expression.
