Gene Details:

• Gene ID: Medtr3g089125
• Gene Symbol: MtSWEET1b
• Gene Name: Sugars Will Eventually be Exported Transporter 1b
• Genome: M. truncatula genome version Mt4.0(https://bmcgenomics.biomedcentral.com/articles/10.1186/1471-2164-15-312)
• Species: Medicago truncatula

Functional Descriptions:

• Heterologous expression of MtSWEET1b in a yeast hexose transport mutant showed that it mainly transports glucose.
• Overexpression of MtSWEET1b in M. truncatula roots promoted the growth of intraradical mycelium during AM symbiosis.
• Arbuscule-specific overexpression of MtSWEET1bY57A/G58D, which are considered to act in a dominant-negative manner, resulted in enhanced collapse of arbuscules.
• Our results reveal a (redundant) role for MtSWEET1b in the transport of glucose across the peri-arbuscular membrane to maintain arbuscules for a healthy mutually beneficial symbiosis.
