Reciprocal regulation between AtFH5-labeled secretory vesicles and PI(4,5)P2 oscillation at the plasma membrane directs pollen germination
{{output}}
Phosphatidylinositol 4,5-bisphosphate (PI(4,5)P2) is known to be an instrumental anionic phospholipid in governing pollen germination and pollen tube growth. However, the precise functions and regulatory mechanisms of PI(4,5)P2 in pollen polarity establishment... ...
