Three symbionts involved in interspecific plant - soil feedback epichloid endophytes and mycorrhizal fungi affect the performance of rhizobia-legume symbiosis
Aims Plants interact by modifying soil conditions in plant - soil feedback processes. Foliar endophytes of grasses exert multiple effects on host rhizosphere with potential consequences on plant-soil feedback. Here, we hypothesize that the grass - endophyte symbiosis impairs soil symbiotic potential...

| 520 | |a Aims Plants interact by modifying soil conditions in plant - soil feedback processes. Foliar endophytes of grasses exert multiple effects on host rhizosphere with potential consequences on plant-soil feedback. Here, we hypothesize that the grass - endophyte symbiosis impairs soil symbiotic potential, and in turn influences legume performance and nitrogen acquisition. Methods Soil was conditioned in pots, growing Lolium multiflorum with or without the fungal endophyte Epichloëand with or without arbuscular mycorrhizal fungi (AMF). Then, Trifolium repens grew in all types of conditioned soils with high or low rhizobia availability. Results Endophyte soil conditioning reducedAMFspores number and rhizobial nodules (menos 27 % and −38 %, respectively). Seedling survival was lower in endophyte conditioned soil and higher in mycorrhizal soils (menos 27 % and más 24 %, respectively). Highrhizobia - availability allowed greater growth and nitrogen acquisition, independent of soil conditioning. Low rhizobia-availability allowed both effects only in endophyte - conditioned soil. Conclusion Endophyte - induced changes in soil (i) hindered symbiotic potential by reducing AMF spore availability or rhizobia nodulation, (ii) impaired legume survival irrespective of belowground symbionts presence, but (iii) mimicked rhizobia effects, enhancing growth and nitrogen fixation in poorly nodulated plants. Our results show that shoot and root symbionts can be interactively involved in interspecific plant-soil feedback. | ||
