The presence of anthocyanins imparts vibrant hues to plants, whose biosynthesis and accumulation is a complex process and are influenced by numerous factors. In plants, sugar acts as a primary energy source and signaling molecule regulating anthocyanins biosynthesis. In this review, we provides a comprehensive overview of the relationship between sugar and anthocyanin. We delved into the intricate biosynthetic pathway of anthocyanins, outlining the key structural genes involved and their functions. Furthermore, we summarized how various environmental factors such as sugar, light, abiotic stresses, etc., affect anthocyanin biosynthesis. Notably, Most notably, we emphasized that sugars can independently regulate anthocyanin biosynthesis by modulating the expression of the MBW complex or structural genes, as well as through cascades involving hormones. These findings offer valuable insights into understanding the molecular mechanisms underlying anthocyanin accumulation and present potential avenues for enhancing anthocyanin content in plants through targeted manipulations that could have applications in agriculture and nutrition.
花青素的存在赋予植物鲜艳的色彩，其生物合成和积累是一个复杂的过程，受到众多因素的影响。在植物中，糖作为主要的能量来源和信号分子，调节花青素的生物合成。在本综述中，我们全面概述了糖与花青素之间的关系。我们深入研究了花青素复杂的生物合成途径，概述了涉及的关键结构基因及其功能。此外，我们总结了糖、光、非生物胁迫等各种环境因素如何影响花青素的生物合成。值得注意的是，我们强调糖可以通过调节MBW复合体或结构基因的表达，以及通过涉及激素的级联反应来独立调节花青素的生物合成。这些发现为理解花青素积累的分子机制提供了有价值的见解，并为通过有针对性的操作提高植物中花青素含量提供了潜在途径，这在农业和营养领域可能具有应用价值。
