Transcriptomic and metabolomic analyses of three Dendranthema morifolium “Boju” varieties with different flower colors

Transcriptomic and metabolomic analyses indicated that the types and contents of anthocyanins varied across the "Boju" varieties, resulting in varying flower color. The key differential metabolites were primarily enriched in the isoflavonoid and flavonoid biosynthesis pathways. The DEGs in the different comparison groups exhibited varying enrichment in different pathways, but the enriched pathways were the same across the varieties.
