Gene Details:

• Gene ID:
• Gene Symbol: HbSUT3
• Gene Name: sucrose transporter 3
• Genome:
• Species: Hevea brasiliensis

Functional Descriptions:

• HbSUT3 encodes a functional sucrose transporter that exhibits high sucrose affinity with a Km value of 1.24mm at pH 4.0, and possesses features typical of sucrose/H+ symporters.
• HbSUT3 was found to be the predominant member expressed in the rubber-containing cytoplasm (latex) of laticifers.
• HbSUT3 expression is induced by the latex stimulator Ethrel (an ethylene generator), and relates to its yield-stimulating effect. Tapping (the act of rubber harvesting) markedly increased the expression of HbSUT3, whereas wounding alone had little effect.
• The expression of HbSUT3 was found to be positively correlated with latex yield. Taken together, our results provide evidence favouring the involvement of HbSUT3 in sucrose loading into laticifers and in rubber productivity.
