Dynamics of the actin cytoskeleton are essential for pollen germination and pollen tube growth. ACTIN- DEPOLYMERIZlNG FACTORs （ADFs） typically contribute to actin turnover by severing/depolymerizing actin filaments. Recently, we demonstrated that Arabidopsis subclass III ADFs （ADF5 and ADF9） evolved...
