| 摘 要： | 对植物花青素生物合成及调控基因的研究进展、基因工程在调控花青素合成途径中的应用进行了综述。植物花青素生物合成属次生代谢途径，对该途径关键酶基因的调控可降低或提高目标化合物的产量，可通过调控植物次生代谢的方式对植物进行遗传改良。对植物通过积累花青素来适应紫外线辐射、防卫害虫及真菌侵害的分子机制进行研究，有助于培育抗病、抗逆的植物新品种。

| Abstract: | This paper reviews the advances in research of synthetic genes and regulator genes involved in the anthocyanin biological synthesis process as well as in genetic engineering in regulating the anthocyanin biological synthesis. Anthocyanin biological synthesis process of plants belongs to the secondary metabolic pathway, regulates the expression of key enzymes involved in the pathway, and could hence lead to a reduced or increased yield of target compound. Genetic improvement of plants may be realized through modifying the secondary metabolic process. Anthocyanin accumulation helps the plants to act against the UV Further study on the defense molecular mechanism of the anthocyanin facilitates b with resistance to diseases and adversities. radiation, insects and fungi. reeding of new plant cultivars |
