中文摘要	为探究半干旱区锦鸡儿属植物根际土壤真菌群落多样性及其与生态因子的互作机制,本研究以不同生境下的中间锦鸡儿和小叶锦鸡儿为对象,采用高通量测序技术分析了2种锦鸡儿根际土壤真菌多样性和群落结构组成及其驱动因素。结果表明:2种锦鸡儿根际土壤真菌隶属于7门20纲43目66科78属。优势真菌门为子囊菌(37.7%)、担子菌(13.7%)和接合菌(4.3%)。在属水平上,青霉菌、地丝霉菌和被孢霉菌为优势属,且土壤中存在根内球囊霉菌和球囊霉菌。小叶锦鸡儿根际土壤真菌群落的Chao1、ACE和Simpson多样性指数显著高于中间锦鸡儿,且2种植物的根际土壤真菌群落结构差异显著。冗余分析结果表明,土壤有机碳、全氮、电导率、速效钾、海拔、全磷和干旱指数是影响土壤真菌多样性的主要生态因子。研究结果丰富了锦鸡儿属植物根际土壤微生物群落多样与生态因子的关系,可为深入理解半干旱区荒漠植物的生态适应机制提供参考。
英文摘要	To investigate fungal community diversity in rhizosphere soil of Caragana species,and their relationships with ecological factors in the semi-arid regions of China,we collected soil samples from Caragana liouana and C.microphylla in different habitats.By using Illumina MiSeq highthroughput sequencing technology,we analyzed fungal diversity,community composition,and the driving factors.Results showed that 7 phyla,20 classes,43 orders,66 families,and 78 genera were recorded from the rhizosphere soil.The dominant phyla in all sample sites were Ascomycota(37.7%),Basidiomycota(13.7%),and Zygomycota(4.3%).At the genus level,Penicillium,Geomyces,and Mortierella were dominant,and Rhizophagus and Glomus were also found in rhizosphere soil.The fungal Chao1 index,ACE index,and Simpson index of C.microphylla were significantly higher than those of C.liouana.There was significant difference between the two species in the composition of fungal communities.Results of redundancy analysis showed that soil organic carbon,total nitrogen,electrical conductivity,available potassium,altitude,total phosphorus and aridity index exhibited significant impacts on soil fungal diversity.Overall,those results enhanced our understanding of the relationships between rhizospheric microbial community diversity of Caragana species and ecological factors,and provided important information on the adaptive mechanisms of desert plants in semi-arid regions.
