Variable Regions of PI4P 5-Kinases Direct PtdIns(4,5)P(2) Toward Alternative Regulatory Functions in Tobacco Pollen Tubes

The apical plasma membrane of pollen tubes contains different PI4P 5-kinases that all produce phosphatidylinositol-4,5-bisphosphate [PtdIns(4,5)P(2)] but exert distinct cellular effects. In the present example, overexpression of Arabidopsis AtPIP5K5 or tobacco NtPIP5K6-1 caused growth defects previo...
