Nitrogen (N) and phosphorus (P) are two of the most important nutrients for plant growth and crop yields. In the last decade, plenty of studies have revealed the genetic factors and their regulatory networks which are involved in N and/or P uptake and utilization in different model plant species, especially in Arabidopsis and rice. However, increasing evidences have shown that epigenetic regulation also plays a vital role in modulating plant responses to nutrient availability. In this review, we make a brief summary of epigenetic regulation including histone modifications, DNA methylation, and other chromatin structure alterations in tuning N and P responses. We also give an outlook for future research directions to comprehensively dissect the involvement of epigenetic regulation in modulating nutrient response in plants.

氮（N）和磷（P）是植物生长和农作物产量的两个最重要的养分。在过去的十年中，大量研究揭示了遗传因子及其调控网络，这些遗传因子与不同模型植物物种（尤其是拟南芥）中氮和/或磷的吸收和利用有关。和米饭。然而，越来越多的证据表明，表观遗传调控在调节植物对养分有效性的反应中也起着至关重要的作用。在这篇综述中，我们简要概述了表观遗传调控，包括组蛋白修饰，DNA甲基化以及其他N和P响应的染色质结构改变。我们还展望了未来的研究方向，以全面剖析表观遗传调控在调节植物养分响应中的作用。
