Plant's ability to perceive, respond to, and ultimately adapt to various stressors is a testament to their remarkable resilience. In response to stresses, plants activate a complex array of molecular and physiological mechanisms. These include the rapid activation of stress-responsive genes, the manufacturing of protective compounds, modulation of cellular processes and alterations in their growth and development patterns to enhance their chances of survival. Epigenetic mechanisms play a pivotal role in shaping the responses of plants to environmental stressors. This review explores the intricate interplay between epigenetic regulation and plant stress mitigation. We delve into the dynamic landscape of epigenetic modifications, highlighting their influence on gene expression and ultimately stress tolerance. This review assembles current research, shedding light on the promising strategies within plants' epigenetic arsenal to thrive amidst adverse conditions.
植物感知、响应并最终适应各种胁迫的能力证明了它们具有非凡的韧性。植物在应对胁迫时,会激活一系列复杂的分子和生理机制。其中包括应激响应基因的快速激活、保护性化合物的合成、细胞过程的调节以及生长和发育模式的改变,以提高其生存机会。表观遗传机制在塑造植物对环境胁迫的响应方面起着关键作用。本文综述了表观遗传调控与植物减轻胁迫之间的复杂相互作用。我们深入探讨了表观遗传修饰的动态景观,强调了它们对基因表达的影响,以及最终对胁迫耐受性的影响。本综述整合了当前的研究成果,揭示了植物表观遗传武器库中具有前景的策略,以帮助植物在不利条件下茁壮成长。
