| Abstract |
- The underlying processes of plant-microbe
associations particularly their interactions with their mycorrhizal
fungal partners have been extensively studied. However, considerably
less is known about the consequences of tree-tree interactions on
rooting zone soil microbiota when tree species of different mycorrhizal
type (myco-type) grow together as mono and mixed myco-type mixtures
along a tree diversity gradient.
- Using the MyDiv tree diversity experiment, where
arbuscular mycorrhizal (AM) and ectomycorrhizal (EcM) trees and their
mixtures were planted in monocultures, two-species and four-species
mixture plots, we investigated the interplay of target tree myco-type,
myco-type mixture, tree diversity and rooting zone compartment (target
tree dominated and its interaction zones with neighbour trees) on the
rooting zone soil mycobiota employing meta-barcoding of the ITS2 rDNA
fragment of the fungal internal transcribed spacer (ITS).
- Our results revealed significant individual and
interaction effects of tree myco-type, myco-type mixture and tree
diversity but not rooting zone compartment on the fungal taxonomic and
functional alpha and beta diversity. This implies intermingling of roots
of target and neighbouring tree species there by reducing the target
tree species effect in its rooting zone. As tree diversity increases, we
found convergence of the fungal community in general, where the fungal
community dissimilarity varies depending on the co-existing tree species
myco-type and tree species diversity. Furthermore, the fungal community
composition in the two and four species mixtures were consistently
influenced by soil pH, whereas in the mixed multi-species stands basal
respiration, N, PO4−, NO3−
were found to be equally important unlike in AM and EcM multi-species
stands. Comparative analysis of the fungal taxa specialisation between
mono and mixed myco-type multi-species stands revealed that the mixed
myco-type plots shared 23.5% (AM) and 19.7% (EcM) of the generalist
fungal communities However, the percentage of specialised fungal
community in mixed myco-type plots (13.2%) was significantly higher as
compared to EcM (9.5%), and significantly lower (9%) as compared to AM
(11.7%) plots, resulting in myco-type and myco-type mixture specific
fungal communities and functional guild patterns
- Our results provide novel insights on the
significance of tree species and its co-existing trees preferred
mycorrhizal association in shaping the target tree rooting zone soil
mycobiome along a tree diversity gradient. Furthermore, it highlights
the significance of generalist and specialist fungal communities in mono
and mixed myco-type stands in modulating tree-tree interaction, tree
species co-existence and regulating soil properties and ecosystem
functions.
