 ==Sucrose Transporter Gene==
 ===Function===
-Plant sucrose transporters (SUTs) mediate the active transport of sucrose across plasma membrane barriers in a process that is coupled to proton symport. Since sucrose is the major carbohydrate translocated through the phloem in most plant species, the sucrose/H+ symporters are thought to play important roles in mediating carbon partitioning in plants, for example apoplastic phloem loading in leaves, transport of sucrose into and/or out of temporary storage sinks such as stem tissue and post-phloem transport of sucrose into sink tissue such as seeds.

 The rice has five families of sucrose transporters. Despite of the previously reported OsSUT1, four putative sucrose transporter are known as OsSUT2, 3, 4 and 5. OsSUT1 encodes a functional SUT protein that is essential for transport of assimilate into filling rice grains. It has also been proposed that OsSUT1 is involved in transport of assimilate remobilised from starch reserves in leaf sheaths and in germinating seeds. Expression of OsSUT3, 4 and 5 in sink rice leaf suggests that they may be important for supplying sucrose, as a carbon source for growing tissues or possibly to supply sucrose to temporary storage tissues.Unlike the other four OsSUT genes, OsSUT2 seems to be expressed at almost equal levels in various tissues of rice plants.
