Gene Details:

• Gene ID:
• Gene Symbol: ShSUT1
• Gene Name: sucrose transporter 1
• Genome:
• Species: Saccharum hybrid

Functional Descriptions:

• Here we present a functional analysis of the SUT ShSUT1 from sugarcane, an important crop species grown for its ability to accumulate high amounts of sucrose in the stem.
• ShSUT1 was previously shown to be expressed in maturing stems and plays an important role in the accumulation of sucrose in this tissue.
• We also found that the sucrose analog sucralose (4,1′,6′-trichloro-4,1′,6′-trideoxy-galacto-sucrose) is a competitive inhibitor of ShSUT1 with an inhibition coefficient (Ki) of 16.5mM.
• ShSUT1 may play a role in retrieval of sucrose leaking from the storage parenchyma cells in the stem or alternatively in sucrose export in sinks rather than in phloem loading.
