Fluorescence Microscopy Composite Image

Caption

This fluorescence microscopy composite image of an Arabidopsis thaliana flower shows 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). A new study describes 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
