Model for repression of ETT/ARF3 and ARF4 by the AS1–AS2 complex and modifiers in the early stage of leaf primordia in Arabidopsis thaliana. Such repression events are crucial for the establishment of adaxial–abaxial polarity and then cell division and growth along the medial–lateral axis. Class 1 KNOX genes are similarly repressed by AS1–AS2 together with modifier genes, although that is not depicted in this figure.
