Integrative analysis of transcriptome and metabolome profiling reveal coloration molecular mechanisms in four rapeseed petals with different color

Abstract Background The colorful rapeseed petals have specific phenotype and excellent ornamental value. However, the coloration mechanism of rapeseed petals are poorly understood. In this study, the integrative metabolome and transcriptome analysis of white, yellow, dark purple, and dark red rapeseed petals were analyzed to elucidate the mechanisms regulating petal pigmentation. Results The metab…
