大叶胡枝子(Lespedeza davidii)为一种豆科灌木,具有较强耐受重金属胁迫及固氮能力,也是矿区一种重要修复植物.丛枝菌根真菌(Arbuscular mycorrhizal fungi,AMF)是一类植物共生真菌,它在矿区与植物共生可促进植物生长、提高植物的抗逆性;但其种类、分布及其影响机制尚不够清楚.以大叶胡枝子灌丛土壤AMF群落为研究对象,采集矿区与非矿区大叶胡枝子冠下及其相邻空旷地土壤进行内部转录间隔区(ITS)测序,分析土壤理化性质,揭示不同样地土壤AMF群落的多样性及其影响因素.研究结果表明:(1)土壤样本共得到 2961 个可操作分类单元(OTU),其中属于AMF的OTU为 66 个;Silva数据库比对发现AMF有 7 目 10 科 1...

Lespedeza davidii is a shrub belonging to Fabaceae,which is also an important phytoremediation candidant plant in mining areas because of its strong tolerance to heavy metal stress and the ability of nitrogen-fixation.Arbuscular mycorrhizal fungi(AMF)is a kind of symbiotic fungi for plants,and its symbiosis with plants in the mining area can promote the plant growth and improve the plant resistance to stress.However,its species composition,distributions and influencing factors are still unclear.The AMF community of L.davidii scrub soil was sele...
