植物已经进化出有效的策略来利用土壤中的营养物质以生存、生长和繁殖。无机磷酸盐（Pi）是植物生长的主要常量元素来源;然而，Pi的可用性和分布在不同地区差异很大。因此，许多地区的植物缺乏Pi。为了维持细胞内Pi的稳态，植物已经发展出一系列适应性反应，以促进外部Pi的获取，限制Pi的消耗，并在Pi饥饿条件下调节Pi的内部循环。本文综述了调控磷饥饿诱导的根构型变化的分子调控因子。
Plants have evolved efficient strategies for utilizing nutrients in the soil in order to survive, grow, and reproduce. Inorganic phosphate (Pi) is a major macroelement source for plant growth; however, the availability and distribution of Pi are varying widely across locations. Thus, plants in many areas experience Pi deficiency. To maintain cellular Pi homeostasis, plants have developed a series of adaptive responses to facilitate external Pi acquisition, limit Pi consumption, and adjust Pi recycling internally under Pi starvation conditions. This review focuses on the molecular regulators that modulate Pi starvation-induced root architectural changes.
