Gene Details:

• Gene ID: Medtr6g087980
• Gene Symbol: MtRac1
• Gene Name:
• Genome:
• Species: Medicago truncatula

Functional Descriptions:

• Here, we found that small GTPases (MtRac1/MtROP9 and its homologs) are required for root hair development and rhizobial infection in Medicago truncatula.
• Phosphorylated MtRopGEF2 can activate MtRac1. Activated MtRac1 was found to localize at the tips of root hairs and to strongly interact with LYK3 and NFP.
• Found that the activated form of MtRac1 strongly interacts with LYK3 and NFP and is polarly distributed at the root hair tips and rhizobial infection sites.
• Taken together, our results support the hypothesis that MtRac1, LYK3, and NFP form a polarly localized receptor complex that regulates root hair deformation during rhizobial infection.
