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.
