The Brazilian Cerrado represents an important hotspot of biodiversity but how different Cerrado physiognomies shape the arbuscular mycorrhizal (AM) community remain poorly understood. We hypothesize that differences in plants and soil properties found across the Cerrado physiognomies would influence the AM community. Thus, soil samples were collected from different physiognomies of Cerrado as follows: Campo graminoide (CG), Cerrado stricto sensu (CSS), and Cerradão (CD). AM community was assessed by 18S rRNA gene sequencing. Glomus was the most abundant genera found in all physiognomies. AM richness and diversity did not change across Cerrado physiognomies. Redundancy analysis clustered physiognomies in different groups, in which CG was the most discriminated, mainly by soil pH and temperature. This study showed that a better understanding of the AM community in the Cerrado biome can help to outline strategies for soil and plant conservation more efficiently, ensuring the sustainability of this system and nutrient dynamics.

巴西的塞拉多（Cerrado）代表着生物多样性的重要热点，但是人们对不同的塞拉多（Cerrado）生理学如何塑造丛枝菌根（AM）群落的了解仍然很少。我们假设，在整个塞拉多（Cerrado）地貌上发现的植物和土壤特性的差异会影响AM群落。因此，从Cerrado的不同地貌收集土壤样品如下：Campo graminoide（CG），Cerrado stricto sensu（CSS）和Cerradão（CD）。通过18S rRNA基因测序评估AM社区。格洛姆斯是所有生理学中最丰富的属。AM的丰富性和多样性在Cerrado的各种生理学中均未改变。冗余度分析将不同类别的生理学聚在一起，其中CG的区别最大，主要是通过土壤的pH和温度来进行的。这项研究表明，对Cerrado生物群落中AM群落的更好理解可以帮助更有效地概述土壤和植物保护策略，从而确保该系统的可持续性和养分动态。
