Abstract excerpt

The formation of leaf polarity is critical for leaf morphogenesis. In this study, we characterized and cloned an Arabidopsis gene, AS1/2 ENHANCER7 (AE7), which is required for both leaf adaxial-abaxial polarity formation and normal cell proliferation. The ae7 mutant exhibited leaf adaxial-abaxial polarity defects and double mutants combining ae7 with the leaf polarity mutants as1 (asymmetric leaves1), as2, rdr6...
