Descripción
Fungal communities play a crucial role in the bioremediation of metal-contaminated soils due to their diverse metal-resistance mechanisms and their functional plant-fungi interactions. In this study, we evaluated the hypothesis that increasing soil lead (Pb) concentrations drive changes in the rhizospheric fungal communities of two native plant species growing in contaminated soil. Taxonomic and functional diversity were assessed by amplicon sequencing of the ITS1 region, followed by functional guild prediction. High fungal diversity was detected across all soil sites, with the phylum Ascomycota emerging as dominant. PERMANOVA and db-RDA analysis revealed that soil Pb contributes to variation in fungal community composition; however, its impact varies depending on the plant species and the specific environmental conditions of each site. The communities included saprotrophic, pathotrophic, and symbiotrophic fungi. The prevalence of metal-tolerant saprotrophs (e.g., Trechispora, Neptunomyces, and Mortierella), alongside widespread occurrence of symbiotrophic endophytes such as Cadophora, highlights their key ecological roles and their plant-associated responses under Pb stress. By integrating taxonomic and functional perspectives of native vegetation, this study identifies ecologically relevant fungal groups that could be harnessed for future bioremediation strategies in long-term contaminated ecosystems.
