Transforming compound leaf patterning by manipulating REVOLUTA in Medicago truncatula

Summary Leaves are derived from the shoot apical meristem with three distinct axes: dorsoventral, proximodistal and mediolateral. Different regulators are involved in the establishment of leaf polarity. Members of the class III homeodomain‐leucine zipper ( HD ‐ ZIPIII ) gene family are critical players in the determination of leaf adaxial identity mediated by micro RNA 165/166. However, their roles in compound leaf development are still unclear....
