Abstract：Flower color is animportant phenotypiccharacteristic of ornamental plants，which isof great significance inenhancing theircommercialvalue.Anthocyaninsarethemainsubstances forthepetal pigmentationofornamentalplants， andtheanthocyaninbiosynthesis ismainlyregulatedbytheinternal structural genesand transcription factorsof plants，in addition totheinfluenceof environment.Inrecent years，withthedevelopmentof research technology，thewidespreadapplicationof transcriptomics，metabolomics，and proteomics hasprovidednewmethodsand means for the studyof anthocyaninsynthesismechanism.Basedontheresearchresultsofanthocyaninbiosynthesisregulationinornamentalplantsathome andabroad，wereviewedthestructureofnthocyanins，biosyntheticpathways，keystructuralgenes，transcriptionfactors and the applicationofomics，and elaborated the regulatory mechanismof genes related to anthocyanin biosynthesis.The aim is toprovidetheoreticalreferenceforthemolecularimprovementofflowercolorandthebreedingof novelvarietiesofonamental plants.
