| 英文简介 | Hedysarum scoparium,which is constructive speices in quicksand environment and endemic species in Asian desert, mainly distribut in desert area of northwest China,and is increasingly paid attention for its differentiation of ecogeographical pattern,growth characteristics and scientific value.The symbiotic relationships between desert plant and soil fungi served as a starting point of this project.Soil and roots samples were collected along with the natural distribution of Hedysarum scoparium for three consecutive years,according to the different ecological sites,host plants and sampling plots.AM and DSE fungi were collected and cultured,and fungal species were classificated and identificated in terms of morphology,micro-morphology,histochemistry,molecular techniques and geographical variation and variation of traits analyzing.The community composition and species diversity of AM and DSE fungi,and interaction with host plants and soil environment. Afterward,the succession dynamics of AM and DSE fungi and formation mechanism of mycorrhizal symbiosis with host plant ecogeographical differentiation were clarified,and the resources of AM and DSE fungi were excavated.In summary,this project is to reveal the symbiotic mechanism of host plant and soil fungi,and ecological strategy adaptable to the extreme desert environments,and provide the basis for mycorrhizal biotechnology for the resource protection and vegetation restoration of Hedysarum scoparium. |
