Other claims from this paper (7)
- Observation The vamp721 vamp722 double mutant had defective cotyledon development, vein patterning and lateral root growth.
- Observation Mutant seedlings showed abnormal auxin distribution and root patterning.
- Observation PIN1, PIN2 and AUX1 accumulated aberrantly in mutant cytoplasm, impairing plasma membrane polar localization.
- Observation VAMP721 and VAMP722 were implicated in FM4-64 endocytosis.
- Observation VAMP721 and VAMP722 were not implicated in PIN2 trafficking to the vacuole.
- Observation Mutant roots had enlarged trans-Golgi network structures.
- Mechanism The authors infer that VAMP721 and VAMP722 mediate post-Golgi auxin transporter movement to the plasma membrane.
