【摘要】 通过对黄色花的花色素组成及其主要花色素生物合成途径中相关酶和基因的介绍,综述了黄色花形成的生物化学及分子生物学机制研究进展,并分析了利用基因工程技术,通过抑制花色苷合成途径中关键酶的基因表达或导入外源黄色花形成相关基因,获得黄色花卉新品种的可行性,以期为开展黄色花分子育种提供参考。同时探讨了黄色花卉基因工程研究中存在的主要问题和应用前景。更多还原

【Abstract】 Based on the introduction of flower pigments composition and related enzymes and genes involved in the main pigments biosynthetic pathway in yellow flowers,study advances on the biochemical and molecular biological mechanism of yellow flowers’ formation are summarized,and the feasibility of using genetic engineering to breed yellow flower plants is also analyzed. The main pathways include inhibiting the gene expression of the key enzymes of anthocyanin biosynthesis or introducing some foreign related genes about yellow flower generation.This view aims to offer the reference on yellow flower molecular breeding.Finally,main problems and perspectives about the research of yellow flower genetic engineering are discussed.更多还原
