However, it is yet unknown whether these trait axes affect the  assembly of soilborne fungi. We expect saprotrophic fungi to link to the  conservation axis of root traits, whereas pathogenic and arbuscular  mycorrhizal fungi link to the collaboration axis, but in opposite  directions, as arbuscular mycorrhizal fungi might provide pathogen  protection.<\/li><li>To test these hypotheses, we sequenced rhizosphere  fungal communities and measured root traits in monocultures of 25  grassland plant species, differing in age. Within the fungal guilds, we  evaluated fungal species richness, relative abundance and community  composition.<\/li><li>Contrary to our hypotheses, fungal diversity and  relative abundance were not strongly related to the root trait axes.  However, saprotrophic fungal community composition was affected by the  conservation gradient and pathogenic community composition by the  collaboration gradient. The rhizosphere AMF community composition did  not change along the collaboration gradient, even though the root trait  axis was in line with the root mycorrhizal colonization rate.<\/li><li>Overall, our results indicate that in the long term, the root trait axes are linked with fungal community composition.<\/li><\/ul>\n\n\n\n<figure class=\"wp-block-image size-large justify\"><img loading=\"lazy\" width=\"648\" height=\"496\" src=\"\/wp-content\/uploads\/image-221.png\" alt=\"\" class=\"wp-image-4450\" srcset=\"\/wp-content\/uploads\/image-221.png 648w, \/wp-content\/uploads\/image-221-300x230.png 300w\" sizes=\"(max-width: 648px) 100vw, 648px\" \/><figcaption>Fig. 1 Hypothesized changes in fungal guild relative abundance along the<br> root economics space (RES).
