Abstract excerpt
In higher plants, class I KNOTTED1-like homeobox (KNOX) gene suppression and leaf polarity establishment are two processes crucial for leaf morphogenesis. The Arabidopsis genes, ASYMMETRIC LEAVES1 and 2 (AS1 and AS2), are required for repressing the class I KNOX genes and promoting leaf adaxial cell fates. In addition, the RNA-DEPENDENT RNA POLYMERASE6 (RDR6) gene acts synergistically with AS1 and AS2 to specify...
