Implication

Observational study reveals uniform arbuscular mycorrhizal fungal communities across three native Brazilian tree species, indicating low host specificity at the genus level.

Key Points

To characterize and compare the genus-level arbuscular mycorrhizal fungal (AMF) communities, spore densities, and root colonization associated with three ecologically and economically important Cerrado tree species.
Collected 63 rhizospheric soil samples from buriti (Mauritia flexuosa), Cerrado cashew (Anacardium othonianum), and pequi (Caryocar brasiliense) in Goiás, Brazil.
Measured spore density per 50 mL of soil, percentage of root mycorrhizal colonization, and the incidence of nine distinct AMF genera.
Evaluated fungal diversity and composition using parametric and nonparametric tests, PERMANOVA, ANOSIM, PERMDISP, and indicator species analyses.
Mean spore densities were 180.9, 153.3, and 148.0 spores per 50 mL of soil for Cerrado cashew, pequi, and buriti, respectively, with no statistically significant differences in spore density or root colonization among hosts.
AMF community composition at the genus level did not significantly differ among tree species, with Glomus and Acaulospora predominating across all hosts and a significant co-occurrence observed between Sclerocystis and Ambispora.
