In this study, we employed comparative genomics and gene ontology theory, and used genome database of Glycine max and its legume model plants Medicago truncatula, Lotus Japonicus, Glycine max to identify 11 candidate genes, ELF3/ELF4, CCR2, CRB, LWD1/LWD2, FIO1, LUX, ZIK4, LIP1, SFR6, ARR3/ARR4 and TEJ, related to circadian clock regulation pathway. We analyzed the functions and evolutionary trends of these candidate clock-related genes by building molecular evolution trees, protein conserved domain and sequence alignment of orthologs genes. The research showed that there are varying degrees of differentiation in the clock-control pathway between Arabidopsis thaliana and legume species, the differentiation between Lotus japonicas, Medicago truncatula and Arabidopsis in clock regulatory networks is greater than between Glycine max and Arabidopsis, this may due to more genomic evolutional events such as duplication and reorganization happened in Glycine max.
