Other claims from this paper (7)
- Observation sec3a mutants were defective in the globular to heart stage transition of embryogenesis.
- Observation SEC3A-GFP localized to the cell plate similarly to other plant exocyst subunits.
- Observation In interphase cells SEC3A-GFP localized to the cytoplasm and plasma membrane as immobile puncta lasting 2–40 seconds.
- Observation SEC3A puncta were equally distributed on root epidermal cells and growing root hairs.
- Intervention effect Brefeldin A inhibition of exocytosis strongly decreased SEC3A puncta density.
- Observation SEC3A did not appear involved in polarized secretion for expansion of tip growing root hairs.
- Mechanism The authors suggested SEC3 landmark function is conserved in plants.
