Abstract:

The sucrose transporters (SUTs) involved in sucrose trans-membrane transportation play a crucial role in the phloem cell-to-cell distribution of sucrose throughout the plant source-sink. This paper introduces the research progresses on sucrose transporters cellar location, functional regulation and sensing mechanism of sugar in high plants.

Key words: sucrose transporter; sucrose; trans-membrane transportation
