    摘要:

    类胡萝卜素和花青苷是抗氧化代谢物,对于植物抵抗光氧化胁迫,赋予叶片、花朵和果实的色泽具有重要价值,同时果实富含的丰富色泽代谢物对人体健康有益。本文总结了光信号对植物类胡萝卜素和花青苷生物合成代谢途径的影响,重点归纳了参与光信号途径的重要转录因子对类胡萝卜素和花青苷合成基因的调控机制,明晰了转录调控在光信号调控类胡萝卜素和花青苷合成代谢中的重要作用,有助于探索光调控果实品质的有效途径和靶基因,为利用基因工程和环境调控促进类胡萝卜素和花青素的积累提供理论依据。

    Abstract:

    Carotenoids and anthocyanins are antioxidant metabolites that are involved in photoprotection, and contribute to the color of leaves, flowers and fruits. Meanwhile, fruits are rich in carotenoids and anthocyanins metabolites, which is beneficial to human health. This review summarized the studies of the effects of light signaling on carotenoid and anthocyanin accumulation and its biosynthetic genes, the major transcription factors and complexes that participate in these pathway. Besides, understanding the crucial role of the transcriptional regulation of carotenoid and anthocyanin by the light may help us to explore effective pathways and targets for fruit quality improvement, and promote carotenoid and anthocyanin accumulation via genetic engineering and environmental treatment.
