Cover image expansion

COVER Fluorescence microscopy composite image of an Arabidopsis flower with six male organs (anthers) bearing pollen grains (blue dots inside) and the central female organ (ovary) bearing two lines of ovules (light blue) targeted by pollen tubes (orange lines). Wudick et al. describe a specific protein family's role in sorting and transporting glutamate receptor–like channels, which drive calcium currents and thus affect pollen tube growth and seed production. See page 533.
