Iris dichotoma Pall., renowned for its high ornamental value, is frequently cultivated in flowerbeds and courtyards, endowing garden landscapes with unique allure. Dark-hued flowers are widely regarded as more aesthetically appealing. This study utilized the petals of two distinct Pall. phenotypes research materials to investigate underlying mechanism flower color formation. The purple-flowered was designated Group P, white-flowered one W. A comprehensive integrative analysis transcriptome metabolome petal types carried out. Metabolomic revealed that contents several anthocyanin derivatives, including delphinidin, petunidin, malvidin, peonidin, procyanidin, were significantly higher purple compared white petals, delphinidin exhibiting highest content. transcriptomic detected 6731 differentially expressed genes (DEGs) between types. Specifically, 3596 showed expression levels while 3135 exhibited lower petals. Ten phenylalanine ammonia-lyase (PAL) genes, chalcone synthase (CHS) anthocyanidin reductase (ANR) gene, 4-coumarate-CoA ligase (4CL) dihydroflavonol 4-reductase (DFR) flavanone 3′-hydroxylase (F3′H) flavonol (FLS) gene identified; they all had displaying than uncovers potential formation anthocyanins types, thereby furnishing a theoretical foundation floral breeding endeavors.
