Functional insights into microbial community dynamics and resilience in mycorrhizal associated constructed wetlands under pesticide stress
Original language description
Arbuscular mycorrhizal fungi (AMF) are critical mutualistic symbionts in most terrestrial ecosystems, where they facilitate nutrient acquisition, enhance plant resilience to environmental stressors, and shape the surrounding microbiome. However, its contributions (especially for microorganisms) to constructed wetlands (CWs) under pesticide stress remain poorly understood. This study investigated the effects of AMF on microbial community composition, diversity, metabolic pathways, and functional genes by metagenomics in CWs exposed to pesticides stress. Using comparative analyses of AMF-colonized and non-colonized CWs, we found that AMF enhanced overall microbial diversity, as evidenced by increases of 2.22 % (Chao1) and 2.83 % (observed species). Under fungicide stress, nitrogen-cycling microorganisms (e.g., Nitrososphaerota and Mucoromycota) increased in relative abundance, while carbon cycle-related microorganisms (e.g., Pseudomonadota and Bacteroidota) generally declined. AMF colonization improved microbial resilience, demonstrated by a 312 % rise in Rhizophagus abundance and significant increases in phosphorus-cycling microorganisms (e.g., Bradyrhizobium and Mesorhizobium). Functional gene analysis further revealed that AMF helped mitigate fungicide-induced reductions in genes related to nitrogen and carbon cycling, lowering the average decline rates to 4.02 % and 1.44 %, respectively, compared to higher rates in non-AMF treatments. In summary, these findings highlight the crucial role of AMF in enhancing pesticide stress resilience, maintaining microbial community stability, and improving the bioremediation capacity of CWs.
