Metabolism and roles of phosphatidylinositol 3-phosphate in pollen development and pollen tube growth in Arabidopsis.
Phosphoinositides play important roles in eukaryotic cells, although they constitute a minor fraction of total cellular lipids. Specific kinases and phosphatases function on the regulation of phosphoinositide levels. Phosphatidylinositol 3-phosphate (PtdIns3P), a molecule of phosphoinositides regulates multiple aspects of plant growth and development. In this mini-review, we introduce and discuss the kinases and phosphatases involved in PtdIns3P metabolism and their roles in pollen development and pollen tube growth in Arabidopsis.
