Arabidopsis phosphatidylinositol-4-monophosphate 5-kinase 4 regulates pollen tube growth and polarity by modulating membrane recycling.

The Plant cell - 1 Nov 2008

Sousa Eva, Kost Benedikt, Malhó Rui

Abstract excerpt

Phosphatidylinositol-4-monophosphate 5-kinases produce phosphatidylinositol (4,5)-bisphosphate [PtdIns(4,5)P(2)] and have been implicated in vesicle trafficking and cytoskeletal rearrangements. Here, we adopted a reverse genetics approach to investigate the function of the Arabidopsis thaliana pollen-expressed gene encoding phosphatidylinositol-4-monophosphate 5-kinase 4 (PIP5K4). Pollen germination, tube growth,...
