Carotenoid cleavage oxygenases (CCOs) play crucial roles in plant growth and development, as well as in the response to phytohormonal, biotic and abiotic stresses. However, comprehensive and systematic research on the CCO gene family has not yet been conducted in Saccharum. In this study, 47 SsCCO and 14 ShCCO genes were identified and characterized in Saccharum spontaneum and Saccharum spp. R570 cultivar, respectively. The SsCCOs consisted of 38 SsCCDs and 9 SsNCEDs, while ShCCOs contained 11 ShCCDs and 3 ShNCEDs. The SsCCO family could be divided into 7 groups, while ShCCO family into 5 groups. The genes/proteins contained similar compositions within the same group, and the evolutionary mechanisms differed between S. spontaneum and R570. Gene Ontology annotation implied that CCOs were involved in many physiological and biochemical processes. Additionally, 41 SsCCOs were regulated by 19 miRNA families, and 8 ShCCOs by 9 miRNA families. Cis-regulatory elements analysis suggested that CCO genes functioned in the process of growth and development or under the phytohormonal, biotic and abiotic stresses. qRT-PCR analysis indicated that nine CCO genes from different groups exhibited similar expression patterns under abscisic acid treatment, while more divergent profiles were observed in response to Sporisorium scitamineum and cold stresses. Herein, comparative genomics analysis of the CCO gene family between S. spontaneum and R570 was conducted to investigate its evolution and functions. This is the first report on the CCO gene family in S. spontaneum and R570, thus providing valuable information and facilitating further investigation into its function in the future
