Diversity and co-occurrence patterns of soil bacterial and fungal communities in two morels

Abstract This study investigates the influence of different morels growth on soil properties, microbial communities, and cultivation outcomes. Through comprehensive analysis, we found that M. sextelata and M. septimelata significantly affect soil physical and chemical properties, including pH and effective content of carbon (C), nitrogen (N), and potassium (K). While both species exhibit similar effects on soil nutrient enhancement, M. sextelata displays superior pH reduction and disease resistance. Microbial community analysis revealed significant differences between M. sextelataand M. septimelata, with M. sextelatashowing a higher abundance of certain bacterial taxa, indicating resilience to environmental stress. Co-occurrence network analysis demonstrates the complexity of microbial interactions, with M. sextelata exhibiting a more intricate network. Moreover, soil phosphorus levels play a crucial role in shaping fungal community structure. Understanding these intricate relationships is vital for effective morel cultivation and ecosystem management strategies.
