Rhizosphere fungal generalists drive plant metabolic adaptability via regulating soil micronutrient availability.

ABSTRACT: The ecological characteristics of fungal generalists (FG) and specialists (FS) in rhizosphere, as well as their impact on soil micronutrient dynamics and plant metabolic adaptability are largely unknown. Through large-scale sampling of Panax notoginseng (with saponins as the primary specialized metabolite) and ecological analysis, we demonstrated that, compared to FS, the assembly of rhizosphere FG is more strongly governed by deterministic processes and that they play more crucial roles in maintaining network stability. Further, Mantel analysis and multiple machine learning models revealed that FG, rather than FS, are significant contributors to soil micronutrient availability, particularly for iron and zinc. This was substantiated by culture-based approaches, where we confirmed the zinc-
