花青素和甜菜色素同为植物水溶性天然色素，在植物中分布和功能相似。前者为苯丙氨酸衍生色素，后者为酪氨酸衍生色素，含有生色团甜菜醛氨酸。花青素在植物中分布广泛，但在石竹目植物中，甜菜色素已经取代了花青素。值得注意的是，从未在同一植物中同时发现花青素和甜菜色素，这种互斥现象可能是由进化中的偶然导致，也可能是因为两种色素共存会对植物的生存造成问题，这一问题一直未解。本文综述了花青素和甜菜色素的概况、生物合成途径及其调控、人工诱导两种色素共存的案例，以及两者互斥的可能原因等研究进展。此外，还讨论了两种色素互斥的可能机制、未来可以开展的研究方向以及在分子育种等各方面的潜在应用价值。本文旨在通过对前人研究的综述及展望，更好地理解花青素和甜菜色素之间的关系，揭示它们存在互斥的原因，并为相关领域的研究和应用提供新的思路和方法。
Anthocyanins and betalains are both natural water-soluble pigments with similar distribution and functions in plants. Anthocyanins is a type of phenylalanine-derived pigment， and the betalains is a tyrosine-derived pigment that contains the chromophore betalamic acid. Anthocyanins are widely distributed in plants， but in Caryophyllaceae plants， betalains present instead of anthocyanins. It is worth attention that anthocyanins and betalains have never been found in the same plant at the same time. This mutual exclusion may be raised by accident in evolution， or the co-existence of both pigments would bring troubles in plant survival. This article reviewed and discussed the general characters of anthocyanins and betalains， the biosynthetic pathways and their regulations， the cases of induced co-existence of the two pigments， and the possible reasons for the mutual exclusion between the two pigments. In addition， the possible mechanism of the mutual repulsion of the two pigments， the research focuses for the future， and the possible application value in molecular breeding are also prospected. The purpose of this article is to better understand the relationship between anthocyanins and betalains through the review and prospect of previous studies， reveal the mechanisms for their mutual exclusion， as well as provide new ideas and methods for research and application in related fields.
