title: Classification of the genes involved in the two-component system of the moss Physcomitrella patens.
abstract: Physcomitrella patens, belonging to bryopsida, is a basal lineage of land plants. To gain insight into the diversification of the two-component system (TCS), which is widely conserved from prokaryotes to eukaryotes, we compiled TCS-associated genes by employing P. patens genome databases. The moss has a set of His-kinases (HKs), including homologs of the cytokinin- and ethylene-receptors in seed plants. In addition, it has a number of coding-sequences specifying unique HKs. We found evidence that a putative cytokinin-receptor HK in P. patans serves as a sensor for this hormone, and that the HK activity of a putative ethylene-receptor homolog is regulated by ethylene, as observed for Arabidopsis thaliana.
