A new class of sugar transporters, SWEETs, has been identified in plants and animals. These transporters are essential for the movement of sugars between cells and play a critical role in plant development, including pollen viability and nectar production. SWEETs are also involved in the nutrition of pathogens, as bacterial pathogens can exploit these transporters to access host nutrients. In plants, SWEETs are expressed in various tissues, including flowers, pollen, and nectaries, and are involved in the transport of sugars to support growth and development. In animals, SWEETs are found in various tissues, including the intestine, liver, and mammary glands, and are involved in the transport of glucose. The study shows that SWEETs function as uniporters, allowing the transport of sugars in both directions. The identification of SWEETs has provided new insights into the molecular mechanisms of sugar transport in both plants and animals. The study also highlights the role of SWEETs in pathogen nutrition, as bacterial pathogens can use these transporters to access host nutrients. The findings suggest that SWEETs are important for both plant development and host defense against pathogens. The study also provides evidence that SWEETs are involved in the transport of sugars in animals, and that they may play a role in the regulation of glucose levels in the body. The identification of SWEETs has important implications for understanding the molecular mechanisms of sugar transport and for developing strategies to combat pathogen infections.A new class of sugar transporters, SWEETs, has been identified in plants and animals.
