Data for: Implications of plant N/P stoichiometry influenced by arbuscular mycorrhizal fungi for stability of plant species and community in response to nutrient limitation
<p>Arbuscular mycorrhizal fungi (AMF) influence plant nitrogen/phosphorus (N/P) by modifying plant N and P uptake, which further affects plant stoichiometric N/P homeostasis. Plant species and community stoichiometric N/P homeostasis can impact plant species and community stability, respectively, in response to variations of soil N and P availabilities. We investigated interspecific plant interactions via AMF in regard to plant and soil microbial N/P stoichiometry across different soil N and P availabilities induced by N and P addition (0 mg N kg<sup>-1</sup>, 25 mg N kg<sup>-1</sup>, 50 mg N kg<sup>-1</sup>, 30 mg P kg<sup>-1</sup>, and 100 mg P kg<sup>-1</sup>). We selected one dominant (<em>Bothriochloa ischaemum</em>; C4 grass) and one subordinate (<em>Lespedeza davurica</em>; legume) species in a natural grassland climax community. We examined how AMF influences stoichiometric N/P homeostasis in monoculture and mixed culture systems, and the resulting consequences for temporal stability of plant species and community in response to variations in soil N and P availability.</p> <p>The AMF mitigated the P limitation of soil microbial communities and decreased the degree of stoichiometric N/P homeostasis of host plants in monoculture. Through their resource-scavenging and soil organic matter mineralisation functions, AMF enhances plant 'luxury consumption', promoting species stability in monoculture in response to soil N and P availability variations. Compared with plants in monoculture, the interaction between <em>B. ischaemum</em> and <em>L. davurica</em> via AMF increased shoot N/P under soil N-poor conditions, leading to an enhanced degree of stoichiometric N/P homeostasis in both plant species, especially the legume.</p> <p>Our results suggest that interspecific plant interaction between C4 grass and legume mediated by AMF confers an advantage in complementarity in plant N acquisition under N-poor conditions, leading to increased stability of plant communities and better maintenance of subordinate species (legume) in response to soil N deficiency.</p>
Contrasting mycorrhizal growth responses in native and invasive woody species are associated with distinct root trait syndromes
<ol> <li>Invasive plant species often express resource-acquisitive leaf traits that support rapid growth, but associated fine root traits and the role of microbial mutualists in invader whole-plant functioning remains poorly understood.</li> <li>We performed an experiment of 12 phylogenetically-grouped native and non-native, invasive woody species, grown with or without a common inoculum of arbuscular mycorrhizal fungi (AMF) across two nutrient levels. We measured 10 fine root traits associated with nutrient uptake and suitability of AMF colonization.</li> <li>The presence of AMF increased the growth rate of all species, but native species were significantly more dependent on AMF than invaders. Further, invaders expressed a distinct syndrome of first-order root traits, including longer, thinner roots of high specific root length, greater branching intensity, and lower tissue density, which are traits associated with rapid nutrient uptake and low AMF association. This syndrome was independent of phylogeny, AMF inoculation, and soil fertility.</li> <li>An acquisitive fine root trait syndrome for invaders supports high photosynthetic and growth rates, linking above- and below-ground functioning. The occurrence of this syndrome across phylogenetic groups indicates that lineages of woody invaders typically associated with arbuscular mycorrhizas may be generally less dependent on AMF than native species.</li> </ol>
