Arabidopsis FAB1/PIKfyve proteins are essential for development of viable pollen.

Plant physiology - 1 Dec 2009

Whitley Paul, Hinz Steven, Doughty James

Abstract excerpt

Phosphatidylinositol 3,5-bisphosphate [PtdIns(3,5)P(2)] is a phospholipid that has a role in controlling membrane trafficking events in yeast and animal cells. The function of this lipid in plants is unknown, although its synthesis has been shown to be up-regulated upon osmotic stress in plant cells. PtdIns(3,5)P(2) is synthesized by the PIKfyve/Fab1 family of proteins, with two orthologs, FAB1A and FAB1B, being...
