Abstract

Although nectar is known to be important, for example in plant–insect interactions, little has been known about the mechanism of its secretion; sucrose phosphate synthases are now reported to be essential for the synthesis of the sucrose component of nectar and the transporter protein SWEET9 is shown to mediate sucrose export into the extracellular space of the nectary.
