Sugar efflux transporters are essential for diverse processes such as nectar production and seed and pollen development, as well for the maintenance of blood glucose levels in animals. These authors identify and characterize a novel sugar transporter family, SWEET, and show that several Arabidopsis, rice and metazoan homologues mediate glucose transport. In addition, some of these transporters are exploited by plant pathogens for nutritional gain and virulence.
