Dashed arrow implies intermediate enzymes and products. The enzymes in red were targeted by CRISPR-Cas9 RNP mutagenesis. The grey or light grey-colored pigments were removed in the LCYE or ZEP knockout mutants, respectively. The bold arrow indicates that lycopene flux is concentrated in the dzlBack to article page
