Figure 3. Phosphoinositide localization in Arabidopsis root epidermis and function in regulating polar auxin transport.

Figure 3

A) Schematic representation of PI3P, PI4P and PI(4,5)P2 and example of their respective function in polar auxin transport. Note that they are likely involved in many more pathways and this represents only the studied examples. B) PIP subcellular localization in Arabidopsis root epidermis. The localization of the respective PIP kinases is indicated when known. Arrows with chevron-shaped arrowhead represent trafficking pathways. C) Model for the plasma membrane localization of PID by PI4P-driven electrostatics.
