摘要

水是生物的基本分子,对生命过程有重要影响。植物是一种无根生物,具有复杂的调节网络,可以调节资源如何在发育和适应过程之间分配。受干旱胁迫的植物可以改变它们的生存策略来适应这种不利的情况。事实上,植物在低水环境中生长时,会修饰、改变和调节基因表达。这种适应通过影响基因表达的几种机制发生,使这些植物能够在干旱地区抵抗。表观遗传调控已成为干旱胁迫相关基因转录调控的主要因素。此外,某些遗传网络表达中的特定分子和表观遗传修饰导致适应性反应,有助于植物在反复胁迫下的适应和生存。事实上,了解植物对包括干旱在内的严重环境胁迫的反应对生物技术的应用至关重要。在这里,我们首先关注植物的干旱胁迫及其对这种胁迫的一般适应机制。我们还讨论了植物在水分胁迫下的表观遗传调控,以及这种适应性是如何代代相传的。

Impact of water stress to plant epigenetic mechanisms in stress and adaptation.

Water is the basic molecule in living beings, and it has a major impact on vital processes. Plants are sessile organisms with a sophisticated regulatory network that regulates how resources are distributed between developmental and adaptation processes. Drought-stressed plants can change their survival strategies to adapt to this unfavorable situation. Indeed, plants modify, change, and modulate gene expression when grown in a low-water environment. This adaptation occurs through several mechanisms that affect the expression of genes, allowing these plants to resist in dry regions. Epigenetic modulation has emerged as a major factor in the transcription regulation of drought stress-related genes. Moreover, specific molecular and epigenetic modifications in the expression of certain genetic networks lead to adapted responses that aid a plant's acclimatization and survival during repeated stress. Indeed, understanding plant responses to severe environmental stresses, including drought, is critical for biotechnological applications. Here, we first focused on drought stress in plants and their general adaptation mechanisms to this stress. We also discussed plant epigenetic regulation when exposed to water stress and how this adaptation can be passed down through generations.

期刊介绍: Physiologia Plantarum is an international journal committed to publishing the best full-length original research papers that advance our understanding of primary mechanisms of plant development, growth and productivity as well as plant interactions with the biotic and abiotic environment. All organisational levels of experimental plant biology – from molecular and cell biology, biochemistry and biophysics to ecophysiology and global change biology – fall within the scope of the journal. The content is distributed between 5 main subject areas supervised by Subject Editors specialised in the respective domain: (1) biochemistry and metabolism, (2) ecophysiology, stress and adaptation, (3) uptake, transport and assimilation, (4) development, growth and differentiation, (5) photobiology and photosynthesis.
