title: Molecular mechanisms of circadian rhythm in Lotus japonicus and Arabidopsis thaliana are sufficiently compatible to regulate heterologous core clock genes robustly.
abstract: Recent intensive studies of the model plant Arabidopsis thaliana have revealed the molecular mechanisms underlying circadian rhythms in detail. Results of phylogenetic analyses indicated that some of core clock genes are widely conserved throughout the plant kingdom. For another model plant the legume Lotus japonicus, we have reported that it has a set of putative clock genes highly homologous to A. thaliana. Taking advantage of the L. japonicus hairy root transformation system, in this study we characterized the promoter activity of A. thaliana core clock genes CCA1 and PRR5 in heterologous L. japonicus cells and found that the molecular mechanism of circadian rhythm in L. japonicus is compatible with that of A. thaliana.
