摘要：为研究海拔高度对刺梨根际土壤真菌与细菌多样性的影响,从而为分离根际促生菌提供参考,采用高通量测序技术分析了不同海拔[1550 m(B1)、1650 m(B2)、1750 m(B3)、1850 m(B4)、2050 m(B5)]刺梨根际土壤真菌与细菌种群组成以及其潜在功能。结果表明,不同海拔刺梨根际土壤真菌与细菌物种数不同,B2样本的真菌与细菌物种数相对较多,B3样本真菌与细菌物种数相对较少。海拔高度对刺梨根际土壤真菌与细菌的分布具有重要影响,镰孢霉属(Unclassified_g__Fusarium)相对丰度随海拔高度增加表现出先降低、再升高、再降低的趋势,鞘氨醇单胞菌(Uncultured_Sphingomonadaceae_bacterium_g__Sphingomonas)则表现出先降低、再升高的趋势。此外,刺梨根际土壤真菌与细菌具有多种功能,根际真菌功能的分布随海拔不同而不同。综上,海拔高度影响刺梨根际土壤真菌与细菌组成与多样性。
The effects of altitude on the diversity of fungi and bacteria in rhizosphere soil of Rosa roxburghii Tratt were studied,which would provide reference for isolating plant growth?promoting rhizobacteria.The composition and potential functions of fungi and bacteria in rhizosphere soil from different altitudes[1550 m(B1),1650 m(B2),1750 m(B3),1850 m(B4)and 2050 m(B5)]were analyzed by high?throughput sequencing technology.The results showed that the number of fungi and bacteria species in rhizosphere soil of R.roxburghii from different altitudes was different.The number of fungi and bacteria species in B2 was the highest,while that in B3 was the least.Altitude influenced the distribution of fungi and bacteria.Unclassified_g__Fusarium showed a trend of first decreasing,then increasing,and then decreasing with increasing altitude,while uncultured_Sphingomonadaceae_bacterium_g__Sphingomonas showed a trend of first decreasing and then increasing.In addition,the fungi and bacteria resources in the rhizosphere of R.roxburghii had multiple functions,and the distribution of fungal functions in the rhizosphere varied with altitude.Therefore,altitude affects the composition and diversity of fungi and bacteria in rhizosphere soil of R.roxburghii.
