The ability of plants to appropriately respond to the soil nutrient availability is of primary importance for their development and to complete their life cycle. Deciphering these multifaceted adaptive mechanisms remains a major challenge for scientists to date. Recent technological breakthroughs now enable to assess the dynamism and complexity of these processes at unprecedented resolution. In this review, we present some of the most recent findings on the involvement of histone modifications, histone variants and DNA methylation in response to nutrient stresses as well as discussing the potential roles these chromatin changes could serve as priming or as trans-generational stress memory mechanisms.
植物适应土壤养分供应的能力对其生长发育和完成生命周期至关重要。迄今为止，科学家们仍面临着破译这些多方面适应机制的重大挑战。最近的技术突破使我们能够以前所未有的分辨率评估这些过程的动态和复杂性。在这篇综述中，我们介绍了组蛋白修饰、组蛋白变体和 DNA 甲基化在应对营养胁迫中的最新发现，并讨论了这些染色质变化作为启动或跨代应激记忆机制的潜在作用。
