Abstract
Leaves are initiated at the flanks of the shoot apical meristem. The flat leaf blade of Arabidopsis plants is mediated by two transcription factor families that impinge on the regulation on a set of target genes. Members of the plant-specific class III homeodomain leucine zipper transcription factor family regulate the development of the adaxial leaf domain (future upper side) while members of the KANADI family mediate abaxial fate (future lower side). We have used genome-wide approaches to identify direct target genes of these master regulators. I will present a summary of past and recent findings. In addition, we know that the set-up of leaf polarity also involves microProteins. Here, I will present our definition of microProteins and describe computational and experimental approaches to identify and characterize these proteins.
