摘要： The present invention provides a novel receptor kinase and the gene thereof which can be used for activating plant defense systems against several pathogens such as fungi. The receptor kinase CHRK1 of this present invention has an extracellular domain similar to a chitinase, and whose gene expression is stimulated by infection of TMV. In addition, the receptor kinase CHRK1 contains a chitin-binding activity as well as a kinase activity so that it binds to chitin of fungal cell wall as a chitin receptor, stimulates a kinase domain, and thus effectively activates versatile plant defense systems. Therefore, the receptor kinase CHRK1 of this present invention can be used for developing plants having high resistance to fungi.
