Abstract

Low phosphate (Pi) availability in soils severely limits crop growth and production. Plants have evolved to have numerous physiological and molecular adaptive mechanisms to cope with Pi starvation. The release of Pi from membrane phospholipids is considered to improve plant phosphorus (P) utilization efficiency in response to Pi starvation and accompanies membrane lipid remodeling. In this review, we summarize recent discoveries related to this topic and the molecular basis of membrane phospholipid alteration and triacylglycerol metabolism in response to Pi depletion in plants at different subcellular levels. These findings will help to further elucidate the molecular mechanisms underlying plant adaptation to Pi starvation and thus help to develop crop cultivars with high P utilization efficiency.

摘要

土壤中低磷（Pi）有效性严重限制作物生长和产量。植物已经进化出多种生理和分子适应机制来应对磷饥饿。膜磷脂中磷的释放被认为可提高植物对磷（P）的利用效率以响应磷饥饿，并伴随着膜脂重塑。在本综述中，我们总结了与该主题相关的最新发现以及植物在不同亚细胞水平上响应磷缺乏时膜磷脂改变和三酰甘油代谢的分子基础。这些发现将有助于进一步阐明植物适应磷饥饿的分子机制，从而有助于培育具有高磷利用效率的作物品种。
