A synteny analysis was conducted on CCO genes in cucumber (Cucumis sativus) using two plant species as references: Arabidopsis thaliana (A) and C. maxima (B). Red and green lines were used to emphasize the syntenic relationships between pairs of CCO genes. These hues can be used to clearly depict the degree of similarity between genetic regions. C Shows the location of CsCCO genes on cucumber chromosomes; lines joining genes on separate chromosomes suggest possible gene duplications
