Abstract:
Plants, like many other living organisms, have an internal timekeeper, the circadian clock, which allows them to anticipate photoperiod rhythms and environmental stimuli to optimally adjust plant growth, development, and fitness. These fine-tuned processes depend on the interaction between environmental signals and the internal interactive metabolic network regulated by the circadian clock. Although primary metabolites have received significant attention, the impact of the circadian clock on secondary metabolites remains less explored. Transcriptome analyses revealed that many genes involved in secondary metabolite biosynthesis exhibit diurnal expression patterns, potentially enhancing stress tolerance. Understanding the interaction mechanisms between the circadian clock and secondary metabolites, including plant defense mechanisms against stress, may facilitate the development of stress-resilient crops and enhance targeted management practices that integrate circadian agricultural strategies, particularly in the face of climate change. In this review, we will delve into the molecular mechanisms underlying circadian rhythms of phenolic compounds, terpenoids, and N-containing compounds.
摘要:
植物,像许多其他生物一样,有一个内部计时器,生物钟,这使他们能够预测光周期节律和环境刺激,以最佳地调整植物生长,发展,和健身。这些微调过程取决于环境信号与昼夜节律调节的内部交互式代谢网络之间的相互作用。尽管初级代谢产物已受到广泛关注,昼夜节律对次生代谢产物的影响尚不清楚.转录组分析显示,参与次级代谢产物生物合成的许多基因表现出昼夜表达模式,有可能增强应力耐受性。了解生物钟与次生代谢产物之间的相互作用机制,包括植物抵抗压力的防御机制,可以促进抗压作物的发展,并加强整合昼夜节律农业战略的有针对性的管理实践,尤其是面对气候变化。在这次审查中,我们将深入研究酚类化合物昼夜节律的分子机制,萜类化合物,和含N化合物。
