    The regularly spaced arrangement of plant organs around the stem known as phyllotaxis depends on auxin-based inhibitory fields; this study identifies another hormone-based inhibitory field downstream of auxin which is generated by movement of the cytokinin signalling inhibitor ARABIDOPSIS HISTIDINE PHOSPHOTRANSFER PROTEIN 6 and regulates the periodicity of organ production.
