Species-dependent partitioning of C and N stable isotopes between arbuscular mycorrhizal fungi and their C3 and C4 hosts

Popis výsledku v původním jazyce

In experiments with nine phylogenetically dispersed AMF strains inoculated on leek (C3 plant) and sorghum (C4) in pot cultures, we measured the 13C/12C and 15N/14N ratios in shoots, roots, AMF spores as well as carbon isotope signature of the C16:1?5 fatty acid (FA), which is diagnostic for AMF. We found no evidence that isotopic partitioning between the partners drives 13C and 15N abundances in plant?AMF symbiosis. Mycorrhizal roots displayed relatively high ?13C typical for heterotrophic organs, and not a mix between AMF and plant signatures. Plant and AMF isotopic abundances hardly correlated with other parameters related to plant development, mineral nutrition or root mycorrhizal colonisation, and these correlations were never consistent between sorghum and leek. Thus, isotopic abundances in plant?AMF symbiosis were rather constrained by each AMF/plant interaction.
