摘要
综述了近年来对植物花斑形成分子机理的研究进展,总结了与花斑形成相关的花色素合成催化酶基因与调节基因,探讨了转座子、启动子、RNA干扰、甲基化、病毒等对花斑形成的作用,并提出了花斑形成分子机理推测模型图,以期为进一步认识花斑形成的分子机理,开展花斑育种奠定理论基础。
Flower blotch is an important characteristic of flower ornamental traits. In previous researches the components and biosynthetic pathway of the pigment of the flower blotch have been understood well. This paper reviewed the recent research advance in the molecular mechanisms of flower blotch formation. The anthocyanidin synthesis catalase genes and regulatory genes related in the flower blotch were summarized,and the roles for the flower blotch formation of transposon,promoter,RNA interference,methylation and virus were discussed. A schematic diagram of the molecular mechanisms of flower blotch formation was calculated for a better understanding of the mechanisms,which would promote the theory study for the breeding about flower blotch.
