Abstract

In this study, 9 kinds of genes related to photoperiod-mediated circadian clock were analyzed by bioinformatics methods in order to identify the genes related to photoperiod that regulate circadian clock in legume, which were Phytochrome, Cryptochrome, LKP1/FKFI/LKP2, PIF3/PIF4/PIF5, SRR1, CO/COL1/COL2, TIC, XCT and FHY3. The results showed that different degrees of differentiation occurred in the 3 species of Arabidopsis thaliana and the legumes. Using Arabidopsis thaliana as a reference, the differentiation degree of Lotus japonicus and Medicago truncatula genes related to photoperiod-mediated circadian regulation network was higher than that of Glycine max, which might be due to the sizes of Lotus japonicus and Medicago truncatula genome is far less than that of Glycine max.
