观赏植物花色形成关键酶查尔酮合成酶研究进展

Research progress of key enzyme chalcone synthase in flower color formation of ornamental plants

查尔酮合成酶(chalcone synthase,CHS)是花色素合成途径中的第1个关键酶,它在植物中表达量的改变,能够影响花朵的颜色,在与花色有关的研究中最多,也最深入。文章详细阐述了植物查尔酮合成酶及其基因在花色上的研究发展情况,即查尔酮合成酶在花色表达中的作用、相应的调控因素及利用方式,旨在为以后利用查尔酮合成酶培育新的花色品种提供理论依据和思考方向。

Chalcone synthase(CHS)is the first key enzyme in anthocyanin biosynthesis pathway.Its expression in plants can affect the color of flowers.It was also studied in the most profound way.In this paper,the progress of chalcone synthase gene in flower color was presented,i.e.the role of chalcone synthase in color expression,the regulating factors,and the use of the corresponding way of using chalcone synthase,to provide theoretical basis and further research for cultivation of new varieties.
