(A) Displays the distribution of OsCCO genes on rice chromosomes, where potential gene duplications are indicated by lines connecting genes on different chromosomes. Panel (B) shows the chromosomal distribution and intrachromosomal linkages of CCO genes between rice-Arabidopsis and rice-Tomato. Red lines represent duplicate CCO gene pairs, while gray lines represent synteny blocks in the rice genome. The chromosome number is indicated at the top of each chromosome, highlighting that segmental duplication of genes is more prevalent than tandem duplication within the OsCCO gene family. This analysis provides insights into the evolutionary history and genomic organization of OsCCO genes.
