Abstract
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.
摘要
磷脂酰肌醇在真核细胞中发挥着重要作用，尽管它们只占细胞总脂质的一小部分。特定的激酶和磷酸酶在调节磷脂酰肌醇水平方面发挥作用。磷脂酰肌醇 3-磷酸（PtdIns3P）是磷脂酰肌醇的一种分子，它调节植物生长和发育的多个方面。在这篇迷你综述中，我们介绍并讨论了参与 PtdIns3P 代谢的激酶和磷酸酶及其在拟南芥花粉发育和花粉管生长中的作用。
