Phospholipids are essential components of biological membranes and signal transduction cascades in plants. In recent years, plant phospholipid research was greatly advanced by the characterization of numerous mutants affected in phospholipid biosynthesis and the discovery of a number of functionally important phospholipid-binding proteins. It is now accepted that most phospholipids to some extent have regulatory functions, including those that serve as constituents of biological membranes. Phospholipids are more than an inert end product of lipid biosynthesis. This review article summarizes recent advances on phospholipid biosynthesis with a particular focus on polar head group synthesis, followed by a short overview on protein–phospholipid interactions as an emerging regulatory mechanism of phospholipid function in arabidopsis (Arabidopsis thaliana).

磷脂是植物生物膜和信号转导级联反应的基本组成部分。近年来，通过表征受磷脂生物合成影响的众多突变体以及发现许多功能上重要的磷脂结合蛋白，植物磷脂研究得到了极大的发展。现在已经接受的是，大多数磷脂在某种程度上具有调节功能，包括充当生物膜成分的那些。磷脂不仅仅是脂质生物合成的惰性最终产物。这篇综述文章总结了磷脂生物合成的最新进展，特别着重于极性头基团的合成，随后简要概述了蛋白-磷脂相互作用，这是拟南芥中磷脂功能的新兴调节机制（拟南芥（Arabidopsis thaliana）。
