Sequence Variations in MYB (v-myb Myeloblastosis Viral Oncogene Homolog) Genes Impair Anthocyanin Biosynthesis and Contribute to Yellow Flower Phenotype in Rehmannia glutinosa.

Abstract excerpt

The corolla of Rehmannia glutinosa typically exhibits a stable reddish-purple color, but a naturally occurring yellow-flowered variant has recently been identified. To clarify the molecular basis of flower color variant, metabolomics, transcriptomics, and variant analyses were integrated. Metabolomic profiling revealed that the yellow phenotype was associated with lower anthocyanin levels and higher carotenoid...
