          摘要:

          類胡蘿卜素和花青苷是抗氧化代謝物,對于植物抵抗光氧化脅迫,賦予葉片、花朵和果實的色澤具有重要價值,同時果實富含的豐富色澤代謝物對人體健康有益。本文總結了光信號對植物類胡蘿卜素和花青苷生物合成代謝途徑的影響,重點歸納了參與光信號途徑的重要轉錄因子對類胡蘿卜素和花青苷合成基因的調控機制,明晰了轉錄調控在光信號調控類胡蘿卜素和花青苷合成代謝中的重要作用,有助于探索光調控果實品質的有效途徑和靶基因,為利用基因工程和環境調控促進類胡蘿卜素和花青素的積累提供理論依據。

          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.
