Fig. 6From: Map-based cloning and characterization of BoCCD4, a gene responsible for white/yellow petal color in B. oleraceaSequence alignment of the BoCCD4 amino acid sequence and four functionally characterized CCD4s from Arabidopsis thaliana, Osmanthus fragrans, Chrysanthemum x morifolium, Prunus persica. Green asterisks indicate the four highly conserved histidine residues as an iron-ligating cofactor; red asterisks indicate the conserved glutamates or aspartate for fixing the iron-ligating histidine residuesBack to article page
