Sucrose is the principal form in which plant biomass, produced in photosynthetic leaves, is transported to non-photosynthetic organs for growth and storage. Sucrose transport proteins play pivotal roles in facilitating sucrose transport around plants. Hence activities of sucrose transporters directly impact on plant growth rates and crop yields. Our aim is to isolate hitherto unknown membrane proteins that move sucrose at high rates between cells and discover their transport properties. Expected outcomes are to better understand mechanisms and regulation of sucrose transport and hence provide novel opportunities to enhance crop yield. The project will foster a productive international collaboration.

蔗糖是植物生物量的主要形式，在光合叶片中产生的植物生物量被运输到非光合器官用于生长和储存。 蔗糖转运蛋白在促进蔗糖在植物体内的转运中起着关键作用。 因此，蔗糖转运蛋白的活性直接影响植物的生长速率和作物产量。 我们的目标是分离迄今未知的膜蛋白，在细胞之间以高速率移动蔗糖，并发现它们的运输特性。 预期的结果是更好地了解蔗糖运输的机制和调节，从而提供新的机会，以提高作物产量。 该项目将促进富有成效的国际合作。
