Phosphorus is essential for plant growth and development, but levels of inorganic phosphate (Pi), the major form of phosphorus that plants assimilate, are quite limiting in most soils. To cope with Pi deficiency, plants trigger a suite of adaptive responses, including the induction and secretion of acid phosphatases (APases). In this article, we describe how Pi starvation-induced (PSI) APases are analyzed, and we provide a brief historical review of their identification. We then discuss the current understanding of the functions of PSI-secreted APases and how these APases are regulated at the molecular level. Finally, we provide a perspective on the future direction of research in this field.
磷是植物生长和发育所必需的，但在大多数土壤中，植物可吸收的主要磷形式——无机磷酸盐（Pi）的含量却相当有限。为了应对磷缺乏，植物会引发一系列适应反应，包括诱导和分泌酸性磷酸酶（APases）。在本文中，我们描述了如何分析磷饥饿诱导的（PSI）APases，并简要回顾了它们的鉴定历史。然后，我们讨论了当前对 PSI 分泌的 APases 的功能的理解以及这些 APases 如何在分子水平上被调控。最后，我们对该领域未来的研究方向提供了一个视角。
