Several root parasitic plants are among the most devastating agriculture weeds. Haustorium is the specific organ connecting parasitic plants and hosts, and it is the bridge of signal and material communication between parasitic plants and host. Haustorium-inducing factors plays important roles in the process of haustorium development. This paper reviewed the development process of haustorium in parasitic plants, the types of haustorium-inducing factors, signal transduction and gene regulation, and how parasitic plants avoid host defense. This
review is expected to provide a reference for further revealing the molecular mechanism of host recognition signal substances in parasitic plants.
