Variable regions of PI4P 5-kinases direct PtdIns(4,5)P2 towards 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)P2) but exert distinct cellular effects. In the present example, overexpression of Arabidopsis AtPIP5K5 or tobacco NtPIP5K6-1 caused growth defects previous...
