摘  要:
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.
