Integrated metabolome and transcriptome landscape of four rapeseed petal colors provides a candidate gene-metabolite roadmap for flower color breeding

Rapeseed ( Brassica napus L.) petals exhibit diverse colors with specific phenotypes and excellent ornamental value. However, the mechanisms underlying their coloration remain poorly understood. Here we performed an integrative metabolomic and transcriptomic of white, yellow, dark purple, and dark red rapeseed petals to systematically dissect the color-specific pigments and their associated regula…
