[Advances in haustoria function of plants obligate parasite-A review].

Haustoria, one of the fundamental characteristics of obligate parasite, is a micro-branch produced by biotrophic fungi and oomycetes, which is composed of haustorial body, extrahaustorial matrix and extrahaustorial membrane. It is an abnormal structure that can invade the host cell interaction with the plant. Haustoria is not only the key factor of biotrophic fungi carrying on the living specimen nutrition way but also represents significant roles in the nutrition biosynthesis and inhibiting the defense reaction of host. The deeper understanding of haustoria will favor us acquaint obligate parasite enormously, so that we can control the corresponding diseases better. This paper summarized the function on nutrition and pathogenicity of haustoria, and the problems and the research trend in this area were discussed.
