Advance and Prospect of Mycorrhizal Physic nut

Physic nut (Jatropha curcas Linn., Euphorbiaceae) is one of the hottest biomass energy plants studied by scientists. This paper first reviewed the symbiosis relationship between physic nut and arbuscular mycorrhizal fungi. The researches have showed that diversity of arbuscular mycorrhizal fungi (AMF) exists around the rhizosphere of physic nut. The AMF hyphae colonize root tips of physic nut to develop arbuscular mycorrhizae. The contribution of mycorrhizal symbiosis relationship improves the nutritional absorption, promotes the growth and development of seedlings, and enhances the stress tolerance capacity of physic nut. This paper also displays a prospect for mycorrhizal physic nut research in the future, such as mycorrhizal system, the molecular mechanism for stress resistance and gene engineering. As an important resource of biomass energy, mycorrhizal physic nut has a huge exploitation potential and practical value.
