Confocal micrograph of a young leaf of Cardamine hirsuta (hairy bittercress) with emerging leaflets, showing distribution of the RCO protein. Cell outlines are shown in gray. RCO shown here in red colour is active at the base of initiating leaflets where it reduces growth, leading to the formation of leaflets that are separated from each other.
