Abstract:
Physcomitrella patens has four homologs of the pseudo-response regulator involved in the circadian clock mechanism in seed plants. To gain insight into their function, Arabidopsis transgenic lines misexpressing PpPRR2 were constructed. Phenotypic analysis of the transformants with reference to clock-related gene expression and photoperiodic responses revealed that heterologous expression of the moss PpPRR2 gene modifies the intrinsic mechanism underlying the circadian clock in Arabidopsis, suggesting that PpPRR2 serves as a clock component in P. patens.
